47 people were killed, 109 injured. 7430 were homeless and extensive damage occurred in the Limon-Pandora area. Intensity X was observed in some areas of liquefaction within the epicentral areas. Damage included landslides blocking roads. 28 people were killed, 454 injured and an additional 2400 homeless and 866 buildings destroyed in the Guabito-Almirante-Bocas del Toro area. Slight damage throughout Central America from Colombia to El Salvador. Maximum uplift was about 1.4 meters near Limon and sandblows and liquefaction caused subsidence of soils in the Bocas del Toro area. Ground cracks were also observed. A 2- meter tsunami started with a recession of the sea of 500 m from the shoreline. During the wave recession people went to the beach to catch trapped fish.

At Winters, CA. Although the total energy expended was probably less, the intensity was as great as that on April 19. The shock was most severe at Winters, about 12 miles north of Vacaville. Many buildings which withstood the previous shock were leveled to the ground.  On Main Street, not a building was left which could be occupied. The buildings were constructed mostly of brick or stone. At Esparto every brick chimney was toppled. Damage was reported from Vacaville, to Fresno and as far east as Reno NV.

 

 4 21 22 32 25 1918  33.750 -117.000   0 6.8   So. California

 

At Riverside County, San Jacinto and Hemet suffered heavy damage. Only one new concrete and one frame building were left standing in the business district of San Jacinto. The buildings wrecked were of brick or artificial stone and old. Well constructed buildings were not heavily damaged. Property loss in the two places was estimated at $200,000. The shock occurred on Sunday afternoon, as loss of life was minimized. Numerous cracks were found in the road between the two towns. Concrete irrigation canals were broken in a number of places.

 

Damage also occurred at Redlands, Riverside and San Bernardino, and as far away as Los Angeles. Roads in the epicentral area were closed to traffic by slides, and one automobile was swept off the road by a slid. Great clouds of dust arose from the mountains and water flow and spring changes were commonplace. Sand and mud craters were formed. In the region of the San Jacinto Fault southeast of Hemet the dry earth surface was broken up as though be a plow.

The Great San Francisco earthquake of 1906 was felt over  1 million square km. 700 were killed and many more were injured. The zone of damage extended from Eureka to Salinas.

 

Although the earthquake did some damage to buildings in general, by far the worst damage occurred, as in 1868 to construction on made land and along the bay shore. The fire that followed the earthquake caused most of the destruction. As in other great earthquakes, the water system was destroyed and the fire raged for 3 days before a favorable change of wind and concentration of efforts along parks and wide street confined it. Dynamiting of structures did not appear to be very successful. The Fire Chief had been killed by a fallen wall at th time of the earthquake. The problems of caring for the dispossessed and re-establishing city life and services was great, about half a million people temporarily left the city.

 

The concentration of shaking was quite complicated. The highest values were aligned along the San Andreas, but areas of higher intensity along the Berkeley Hills and in the San Joaquin Valley near Los Banos suggest movement on other faults as well. Sympathetic movement probably took place along the Hayward, and faults in the San Joaquin valley.   Dextral strike slip movement took place on the San Andreas fault from  San Juan Bautista to at least Punta Arenas. Another fault trace was found to extend to Petrolia. The largest displacement was in Marin County on the Point Reyes Peninsula where displacement of up to  7 meters were observed in soft alluvium and up to 5 meters on solid ground.

 

Vertical displacements of up to half a meter were noted in many places. These tended to be small and disappear with the passage of time. Similar effects have been noted in other large earthquakes (notably in Chile in 1835 and 1960).

 

Aftershocks continued for more than a year. A far-field aftershock on the same day as the San Francisco quake but in Brawley was felt over all of the Imperial Valley and into San Diego.

 

As a result of the California earthquake of 1906, the Seismological Society of America was formed and the elastic rebound theory of earthquakes was enunciated by Ried (1910). If it were not for this earthquake the true nature of the San Andreas Fault might not yet be recognized.

Dynamiting of structures did not appear to be very successful. The Fire Chief had been killed by a fallen wall at th time of the earthquake. The problems of caring for the dispossessed and re-establishing city life and services was great, about half a million people temporarily left the city.

 

The concentration of shaking was quite complicated. The highest values were aligned along the San Andreas, but areas of higher intensity along the Berkeley Hills and in the San Joaquin Valley near Los Banos suggest movement on other faults as well. Sympathetic movement probably took place along the Hayward, and faults in the San Joaquin valley.   Dextral strike slip movement took place on the San Andreas fault from  San Juan Bautista to at least Punta Arenas. Another fault trace was found to extend to Petrolia. The largest displacement was in Marin County on the Point Reyes Peninsula where displacement of up to  7 meters were observed in soft alluvium and up to 5 meters on solid ground.

 

Vertical displacements of up to half a meter were noted in many places. These tended to be small and disappear with the passage of time. Similar effects have been noted in other large earthquakes (notably in Chile in 1835 and 1960).

 

Aftershocks continued for more than a year. A far-field aftershock on the same day as the San Francisco quake but in Brawley was felt over all of the Imperial Valley and into San Diego.

 

As a result of the California earthquake of 1906, the Seismological Society of America was formed and the elastic rebound theory of earthquakes was enunciated by Ried (1910). If it were not for this earthquake the true nature of the San Andreas Fault might not yet be recognized.

Qir completely destroyed. 5054 were killed and thousands injured. The damaged region extended over 1,000 sq. km. It was felt widely in southern Iran.

 

More than 20 villages were reduced to rubble and over 30,000 were left homeless. Gaping cracks and considerable ground failure accompanied this shallow earthquake. There was also a report of a volcano near Ghir which was shaken into eruption. The tremor was felt over 500 square miles. Hardest hit were farming villages where mudbrick construction is especially vulnerable to earthquake damage. In Ghir more than a third of the total population was missing and presumed dead. Not a wall stood there. Aftershocks continued for days adding to damage and misery. Most of the victims trapped in the crumbling houses were women and children.

 

Among the horror there were a few miracles. Some persons were buried up to 36 hours before being rescued alive.

A strong earthquake shock the whole of Luzon and Northern Visayas. Damage was done to schools in Manila. Buildings in Central Manila suffered slight damage. Manila International Airport suffered cracked walls and broken Windows. 14 were killed and hundreds injured. The deaths all resulted from the mainshock. Dozens of injuries, however resulted from the most sever aftershock on April 12. Considerable damage occurred to buildings on Alluvial ground in Manila. Severe damage was done to roads and bridges in the epicentral areas. Estimated cost to injured coconut trees - $2 million. The earthquake was characterized by "short rapid jerks, zigzags rather than arches". This quake radiated from the point of the fault-line that runs along the Philippine Pacific coast. People at the shore towns "saw the sea pushed back, saw the water tripped off like a carpet from the shoreline and folded up into the horizon. But the next moment the folded sea unrolled and came rushing back as a wall of water, sort of tide, a mile-wide torrent that flowed and crashed past the shoreline, engulfing trees, boats, huts and beach". Roads split was two feet, water fountained from the deep chasms created, bridges collapsed.

The correct date is probably April 16 (Gregorian) wile April 5 is the Julian date. Intensities of this event were as high as IX in the islands of Antigua, Monserrat, St. Kitts and Nevis.

 

At Antigua, stone houses suffered much, most houses were shaking down or were so split and cracked that they had to be leveled. A spit at Redonda called Rockadunda was split and turned into the sea. Landslides occurred on Nevis Peak. The sea withdrew about 500 feet from Charlestown before returning after two minutes in a tidal wave. The earth opened up to 9 feet in some places and buried solid timber sugar mills. This is one of the two largest earthquakes recorded in this region of the West Indies.

The earthquake that struck the Dharamshala-Kangra area in Himachal Pradesh

on April 4th, 1905 is among the deadliest earthquakes in the history of India. According to the provincial government of Punjab, 19,727 people were killed at Sialkot. Many of the fatalities were from Dharamshala, Kangra and neigbhouring towns and villages. Felt from Afghanistan to Bengal.

 

All the buildings were destroyed at Kangra including numerous churches and temples.

 

One major difficulty in this event was that most government officials were killed and there was no one to supervise the rescue and cleanup efforts. Most of the deaths were due to the ground shaking. Landslides, liquifaction and other earthquake effects caused extensive damage throughout the region.

This was the strongest earthquake ever recorded in Hawaii. Nearly every wooden house at Keiawa, Penaluu, Ninole and beyond was  knocked off it's foundation or tumbled over (recall that the Unimak tsunami hit Ninole on this day in history April 1, 1946). It shock down  alomost every wall in Hilo and caused landslides beyond Hilo. Fissures opened and brooks became muddy. In one place a fissure opened about two feet and then closed, the two sides were then several inches from coincidence. At Kealakekua strong trees were bent backward and forward like reeds in a storm. At Kohala, it was reported that the force of the shock stopped all sugar mill engines, even the large 75-horsepower engine which was running at the time with  a full head of steam. Ground waves estimated at 1-2 feet from trough to crest were observed at Kohala. Rumbling sounds were heard and clocks were stopped at Honolulu.

 

A tsunami struck the Kau-Puna coast, adding to the devastation. It was  reported that the wave rolled in over the tops of the coconut trees, a height of at least 60 feet.  Most houses were swept out to sea and a number of persons were drowned. At Hilo the tsunami was 10 feet.

 

On April 7 a powerful volcanic eruption began starting in the fissure formed at the time of the earthquake.

This earthquake has been recalculated and was apparently much larger than originally believed. It occurred south of Unimak Island, Alaska. Minor damage occurred to Navy buildings a short distance inland from Scotch Cap Lighthouse on the southwest coast of the island. A few minutes after the earthquake a tsunami destroyed the lighthouse and took lives of the five attendants. Effects clearly indicated that the wave reached a height of 90  to 100 feet. Minor wave damage in the Aleutians occurred at Dutch Harbor and at Ikatan Island. Many aftershocks were felt, principally on Ikatan Island. Aftershocks were also reported from Chignik, Cold Bay, Sanak Island  and the Shumagin Islands. The great distance between the instrumental epicenter and the aftershock locations suggests they may not have originated at the point of the mainshock.

 

The tsunami effects were disastrous in the Hawaiian Island (called the Laupahoehoe Tragedy of 1946). 173 lives were lost and damage was estimated at $25 million. A major portion of the damage occurred at Hilo. The wave was also noted in the Society and Marquesas Islands and at many points on the Pacific shores of North and South America.

The earthquake extended from Lima to Callao. Felt at Arequipa but not at Arica. A very violent earthquake lasted 40 seconds, with many aftershocks. Great damage was done, Scarcely a house in  Lima or Callao remained uninjured and walls of 6 and even 9 feet thick were thrown down. The cloud of dust which arose from the ruined buildings of Lima was seen at Callao before the shock itself was felt there. At Surras streams of water burst forth from the earth. At Truxillo and elsewhere in the northern part of the district shake, the most extraordinary and violent rain followed, lasting four days and produced most disastrous inundations. On board the ship 'Volant' the shock is said to have been felt before it was perceived on shore, while the accounts from other  vessels agree in saying the earthquake was first felt on land.

 

An interesting phenomena, which might have also been observed in the Izmit Turkey quake of 1999 related to a ship at sea. Some of the phenomena observed on board the ship in the harbor of Callao were remarkable. On board the 'Volant' about half past seven, a noise like distant thunder was heard, and then came a shock, compared to jolting over a rough road in a poorly constructed cart or to the vessel striking upon rocks of sandbanks (a seaquake). The water which was 25 fathoms deep, hissed and boiled as if red hot iron had been thrown into it, and the surface was covered with bubbles of gas of a sulfurous odor and quantities of dead fish. The sea had been quite clear, but was now disturbed and muddy. The ship swung to the extent of 14 inches on either side. On weighing anchor, the chain cable on one of the anchors was found to be half melted in a considerable part of its length, the links being  drawn out and also lengthways. The chain of the second anchor was quite uninjured as were those of all other ships in the bay. Note the similarity to the story of the fishermen in the sea of Marmara - melted nets, fried fish, bubbling sea. Could this be a case of sonoluminescence?

 3 28  3 36 14 1964  61.040 -147.730  33 9.3   Central Alaska

 

This has been called the largest earthquake ever recorded in the U.S. or Canada at Mw 9.3. It was felt over approximately 700,000 square miles of Alaska, the Yukon and British Colombia, Canada. This was one of the most violent every recorded and vertical displacements were found over and area of 200,000 square miles.  On the southeast end of Montague Island vertical  displacement was up to 50 feet.

 

While uplift was great so was subsidence. The zone of subsidence covered and area of about 110,000 square miles and included the western portions of Prince William Sound and nearly all of Kodiak Island.

 

The earthquake generated many tsunamis either directly or through landsliding. These devastated towns along the Gulf of Alaska and in Hawaii and California.

 

The low population of the area and the time of occurrence when schools and businesses were closed or uncrowded and low tides conspired to keep the death at about 131. The greatest damage occurred in Anchorage 80 miles from the epicenter where there were rock and mud-slides, slumping, water spouts, liquefaction and sand boils.

 

There were thousands of felt aftershocks in the months to come and total cost was estimated at $400 to $500 million.

 

 3 28 10  8 43 1964  43.000 -101.600  16 5.0   Wyoming/Dakotas

 

A foreshock occurred on March 27. Furniture vibrated and moved at Van Tassell. Also felt in Nebraska and South Dakota.

 

This event was felt over a large area of Nebraska, South Dakota, and border areas of Montana and Wyoming. It was the most widely felt shock since that of November 15, 1877 and was the first to center in Nebraska since March 1, 1935. At Alliance, part of a  Chimney cap fell on one residence. A highway about 10 miles south of Merriam sustained about 75 cracks and steep banks reportedly fell into the Niobrara River. Plaster fell, walls cracked and several dishes broke. Slight damage was also obtained in Martin and Deadwood, So. Dakota. The logical conclusion is that this event and the others in the western U.S. on this and the previous date were in some way related to the great Alaska earthquake.

In the Ridgedale area of the sparsely populated Pocatello Valley, this earthquake shifted several ranch houses on their  foundations and toppled many chimneys. At Malad City, 20 km northeast of this epicenter about 40 percent of Chimneys  were toppled. Total property damage was estimated at $1 million.  Ground fractures were contained in a zone about 0.6 km long by 5 cm wide. The shock triggered many snow avalanches northeast of the valley. The largest earthquake ever located in this region.

A great earthquake and tsunami hit the City of Merida de Caracaybo. The shock hit Caracas and the surrounding countryside, particularly in the high mountains of Merida and as far as Cartegena in the Andes.

 

The shock was felt on ships in the port of La Guayra as if they had been on the rocks. Huge waves were reported to overcome sea walls.

 

The earthquake had been accompanied by a noise louder than thunder. Caracas was utterly ruined in this terrible earthquake. The earth at that place appeared like the surface of a boiling  liquid. At Valencia an immense torrent of water burst forth and Lake Maracaibo was lowered. Large masses of rock were detached and hurled down from the mountains. The sky was clear and the night calm and beautiful. Not a drop of rain had fallen in the previous 5 months.

 

The shocks were more violent in the gneiss and mica-shist of the mountains than in the plains. There were very slight  in the valleys. The towns that were ruined were said to be "thrown down" like houses of cards. The shocks of the 27th  were accompanied by very loud and prolonged noises. On the 5th of April the ground was in a state of undulation for several hours. On April 24 the first eruption of St. Vincent commenced. The noise from it was heard at Caracas and the country about April 30.

This is the Owen's Valley earthquake, one of the largest ever recorded in California.  The great earthquake was felt as far as Arizona and Utah. At Lone Pine 27 people were killed out of a population of 250. Fifty-two of fifty-nine houses in the town were destroyed as  were most of the houses between Owens Lake and Bishop. Death and injury were mainly due to collapse of adobe buildings. Severe damage occurred as far away as Visalia and Grass Valley. Rock falls were widespread. The air was filled with dust until noon. Falling boulders gave off sparks which ignited many fires. One of the more interesting tales has to do with a government mule team at Camp Cay that was thrown to the ground by shocks, what thery were doing at that hour in that season (2:00 in the morning) is indeed puzzling as Richter (1958, p 501) comments. (This location was about 200 miles from the epicenter).

 

The geologic effects of this quake were marvelous and some may be seen to this day. A series of fault traces showing both horizontal and vertical displacements together with lurches and assorted fractures were noted from near Little Lake to as far north as Bishop. The block  of land on which Owens Lake is situated tilted down 0.5 meters to the NW as evidenced by the height of water at that point compared to water on the NE edge. A notable tsunami occurred, the water first retreated and then rushed up some 60 meters beyond the usual shoreline. North of Lone Pine the Owens River was shifted to the west. Sloshing of the water left fish stranded on the river banks. The river ceased to flow at Lone Pine for several hours following the mainshock, this was probably caused by a landslide dam although Whitney (1872) attributed it to the water being drawn off by the many fractures.

 

There appears to have been a horizontal displacement of about 5 meters and about 7 meters vertical maximum. Houses on the east side of the fault fell to the north. Scarps were seen throughout the region.

There were 25 reported killed in an earthquake near Conception, Chile on this date in 1751. A large tsunami was generated which did damage locally. There is one report this event occurred in March, however most authorities believe this earthquake actually occurred in May with the word Mayo mistranslated to March in English translation. This is a common problem in historical seismicity studies and leads to the appearance of many double events in the literature.

Considerable amount of minor damage was done at Boulder City, consisting of cracked plaster and broken dishes. Several rockslides onto roads  occurred in the Boulder City area. This was one of many earthquakes associated with the filling of Lake Powell. Large reservoirs often induce seismicity as they are filled because of loading and seepage of water into surrounding earthquake-prone areas.

This event was felt  over 7500 square miles of eastern California and western Nevada. The only report of damage was a crack in a patio near the epicenter, however many were frightened or awakened by this early morning earthquake. A similar earthquake had occurred on March 22 1953 in the Markleeville, CA region. This event also frightened many. Houses creaked and  objects were moved. A very loud rumbling sound preceded and accompanied the earthquake.

The most disastrous earthquake in the recorded history of Spain occurred on June 21, 1829. This event was felt in province of Murcia, Spain, but was slightly felt to Madrid. The valley of Segura seems to have been the center of the disturbance for the shocks were most violent there. The earthquake was preceded by a slight shock at noon but about 6 hours later the mainshock came accompanied by loud underground noises. The earthquake lasted at least a minute at very severe levels.  The damage done was enormous in very many towns and villages of Murcia, and in Guradamar, La Mata and Torrevieja in Valencia. Some places were totally ruined and the destruction of churches, houses and loss of life were terribel. The precursory noise like thunder was heard at Torrevieja for more than three-quarters of  an hour. It generally resembled cannon explosion and sometimes  increased gradually and then ceased. It was not heard thereafter until the following September. At Daja Naeva and Daja Vieja fissures opened in the earth, and small holes appeared from some of which large quantities of dey sand and form others of sand and  water were thrown out. In Estremadura, the waster of a lake suddenly disappeared. On the right bank of the Segura, it was remarked, the shocks were more numerous and lasted longer than  on the left bank. The course of the river changed and now enters the sea at  different place than it had before the  earthquake.

This event was felt over approximately 40,000 square miles of southern California and portions of southwestern Nevada and western Arizona. There were many aftershocks. In many areas groceries, vases, and small objects were knocked from shelves. In some areas glass was broken. At Coachella many were frightened. Pendulum clocks stopped and many objects fell from shelves. Near panic was reported at the local prison as the jailhouse rocked (could this be the origin of the song "Jailhouse rock" which was written about the same time?). The earthquake occurred at 01:54 a.m. Police report that bedroom lights snapped on throughout the county after the quake. At Oasis, north of Coachella a concrete surface irrigation pipe broke. At Palm Springs a water pipe broke to a hotel, and several swimming pools were cracked. A parked truck started rolling and caused an unmanned collision. San Bernardino suffered a temporary power blackout as two lines swung together.

The only earthquake known to have caused loss of life on this date occurred in Luzon, Philippines in 1973. This earthquake had it's maximum intensity at Hondagua, Lopez, Calauag and Guiyangan, Quezon Province. It was felt over an area of 157,000 sq. km. At the height of the earthquake, people panicked. They had to hold on to stable objects to maintain their balance. There were reports of  changes in the flow of springs and wells. Sand and mud were ejected from fissures in soft ground. A reinforced concrete highway bridge collapsed. Within the epicentral area the inhabitants heard rumbling sounds coming from different directions during the occurrence of the  mainshock and during he larger aftershocks. Those closest to the fault-line either fell down or were thrown up for a few feet due to the initial vertical jolt of the earthquake. Four-footed animals such as buffalo and cows were likewise knocked down. Piles of coconut trunks lying five meters away from the fault-line in the Sintones District were thrown southwestward, pinning down and killing a man who was lying down nearby during the time of the main shock. An employee of the Philippine National Railways in Hondagua,Lopez, who was sitting with a clear view of the rails reported the dislodgment in a wavy form of the rails from the ground. Some people reportedly saw the ground heave up and down in a dizzying wave-like manner. A tsunami at the western end of the sea wall in Calauag was observed to go beyond the shore by 20 meters. This was due to a rise in the sea level of about 1.3 meters. Similar effects were also noted elsewhere. The worst hit town was Quezon where 98 houses were totally destroyed and 270 others partially collapsed. 70% of the schools were destroyed. There were observations of mud boils, liquefactions and landsliding

 throughout the region. Cracks up to half a meter wide formed in some areas.  The prime product of the area is coconut palms. Most palms within 1 km of the fault on both sides died as water to the roots was cut off by the earthquake. The downturn in the production of coconuts caused  major economic difficulty for the area throughout the next year as the earthquake occurred when the coconuts were young and were shaken off the trees.

In 1860, an event estimated a Mw 7.0 occurred near Carson City, in western Nevada. This earthquake was felt over a considerable area of Nevada and portion so of north and Central California. The MMI intensity in the epicentral area is unknown as the quake occurred in an unsettled region . It was very violent at Carson City where merchandise was thrown from shelves. Rock and landslides were reported from Pyramid Lake and Carson City. The quake was felt as far as Yreka, CA and to Utah in the east.

The other event of note for today occurred in 1946 (March 15) in the Walker Pass/Coso Junction region of California. This earthquake caused moderate damage at Onyx SW of the epicenters. Damage to brick buildings, chimneys, walls and plaster occurred. Concrete was broken up. Dishes broke, windows cracked and books and pictures fell. Cracks formed in the ground and in the Los Angeles Aqueduct  where boulders fell blocking the line near San Canyon. There were landslides in many of the local canyons. Pipes were broken as far away a Bakersfield. This Ms 6.4 earthquake was felt as far away as Calaveras County in the north to San Diego in the South and from San Luis Obispo to Death Valley (an area of about 65,000 square miles).  The earthquake was preceded by a foreshock, felt by many but described as slight. It was followed by a strong series of

aftershocks.

The event caused great destruction, but loss of life was minimal. The following report from Davao City Mindanao is from: Series on Seismology, Volume IV, Philippines, by Lolita Garcia et al,  June 1985, Southeast Asia Association of Seismology and Earthquake Engineering.  " ... very violent earthquake from SE-NW, which lasted from four to five minutes. Before the first movement there were subterranean noises from the SE which lasted two minutes. Pendulum clocks were stopped and bottles and other objects fell from the shelves in the houses, bells rang, and fissures were opened up, from which water and fine sand came. The debris fell to the SE. Several walls in the church and convent were thrown down, while in the town, the palm  thatch houses rocked a good deal and many of them remained out of plumb; crockery was broken in all of them. 'This earthquakes is a sever one; from the beginning I observed some of the oscillations and movements of the church and convent to be so large that it was a marvel that they were not brought to the ground. Not being able to remain upright, I knelt down but even so I could not keep still, so I lay down on the ground till the vibrations ceased, which  appeared to me to be about two minutes. The earthquake seemed to  be entirely oscillatory, without vertical shocks, which was the reason so little damage was done.' (Rev. R. Poruga, S.J., Davao)" A slight tsunami was generated in lakes and rivers. The earthquake was not so notable for it's damage but for it's duration. Most buildings are built to withstand horizontal forces and did not come down when the motion was mostly horizontal. It is vertical motion combined with horizontal that usually levels buildings.

The Hindu Kush earthquake on this day was a Mw 7.8 and occurred on March 14, 1965. Because of the great depth of this event (about  219 km) little damage was done on the surface. This is quite typical of many large earthquakes in Hindu Kush. The event on  March 3, 2002 was atypical in that it did considerable damage and was said to have killed more than 100.

The only other deadly earthquake on this date occurred in  Mexico in 1979. This Mw 7.6 killed 5 and caused severe damage throughout the Guerrero state. Slight damage was also suffered at Acapulco and Guadalajara, Monterrey and Puebla. This Mexican earthquake was followed slightly more than a day later by a swarm of earthquakes in the Lander's region of southern California in the Homestead region. These earthquakes started with a Ml 4.9 and built to a maximum size of Ml 5.7. A strong aftershock sequence lasted for more then two days. The distance between the Mexican and the subsequent So. California event is approximately 19 degrees, a distance where some believe Far-field triggering is prominent. Were the events in So. California triggered by the Mexican earthquake the day before - anybody's guess.

The largest recorded earthquake to hit Utah since settlement occurred there in the 19th Century occurred on March 12, 1934 (Ms 6.6). The earthquake occurred in a sparsely populated area and killed only two people.  Property damage was limited to cracked walls and downed chimneys throughout the Kosmos/Lake Bonneville areas of Utah.  Rock slides were observed just north of Monument Rock and near Snowville, Utah. Several other minor rockslides were also observed.  A number of ground cracks were developed in the epicentral area. Most of the cracks were in salt flats or poorly consolidated gravels. None were continuous for long distances. Four distinct fractures about 1 km apart developed across a road about 5 km north of Kosmo, UT. The vertical displacement along the fractures ranged from about 7.5 to 25.5 cm. Precise leveling surveys showed subsidence in some areas up to nearly  a half meter. There was no horizontal displacement. In some areas the cracks stayed open for up to a foot and a half. One graben was noted north of Kosmo about 60 feet across with the displacement of 8 inches on the west side and 5 inches on the east side. This suggested nearly vertical motion was involved with the sinking of blocks within graben-like structures. Hansel Valley is very similar to other such grabens in Nevada and Utah being of the basin and range type. It trends north and south and has very steep slopes. No fractures were noted in bedrock, however, so what was observed may be surface expressions in unconsolidated material. Numerous springs developed in the epicentral area as a result of the earthquake. All apparently rose along well-defined  fractures and most formed in salt-flats. All the water flowing from the springs had a strong salty taste, this would be expected as it flowed through salt beds. Considerable water also flowed from fractures at Monument rock, especially from two holes in salt flats northeast of there one of which had diameter of 3 meters and depth of 11 meters.  In addition to the springs, water flowed from an old well, but within days had ceased. It appeared as if the water was forced from the ground under considerable pressure. Water in some wells was observed to rise up to 12 feet. Oil seeps were also observed 10 miles south of Promontory rock. In the epicentral area the ground motion was described as "bumping". A farmer near Kosmo stated that movements in his pasture resembled waves on water - an observation often made in large earthquakes. Many reported sounds of a roaring, rumbling thunderous nature like the passing of a train and these sounds were heard as far away as Salt Lake City nearly 70 km away.  The area had shown seismic activity for some years prior to this earthquake.

Since this is an unusual event, especially since it is so large for an area with normally subdued seismicity, it is suspect. The Significant earthquake catalog identifies the source as a Rothe paper from 1938 in which he stated the earthquake killed 4 and inflicted heavy damage in the Chamonix Valley in France. This event, however is not listed in the French earthquake catalog: Les tremblements de terre en France by J.Vogt. No reference can be found to it in other contemporary catalogs either, suggesting it was a local event and the Magnitude 8 assigned to it was really an MMI VIII report.

The event occurred on March 10, local time, but time is usually referred in earthquake catalogs to UT. The following discussion is partially from  "Earthquake Investigations in the Western  U.S., 1931-1964" by Karl V. Steinbrugge and Vincent R. Bush, Publication 41-2, U.S. Dept. of  Commerce, CGS.  This earthquake (Ms 6.3) was the first strong event this century in southern California during the 20th Century and "marks a major  turning point in the field of earthquake-resistive design and construction for much of California. Earthquake bracing provisions up to that time were not containeded in any of the metropolitan Los Angeles building ordinances, including that of Long Beach. There had been controversy regarding the potential earthquake hazard to the Los Angeles area. One book, authored by a prominent geologist and published in 1928, stated: 'The accumulative weight of data substantiates beyond a doubt any deduction that Los Angeles is in no danger of a great earthquake disaster.' The 1933 Long Beach disaster brought the debate to a close. The earthquake had a Richter magnitude of 6.3. The instrumental epicenter, not far from Huntington Beach was about 10 miles  southeast of Long Beach in the Pacific Ocean. Property damage was estimated to be from $40 to over $50 million." It was not a huge quake from seismological considerations, however the MMI was IC and occurring in a populated area made it significant from an engineering standpoint.  Until the San Fernando, Northridge and Loma Prieta earthquakes, the shock was second only in destruction to the San Francisco earthquake of 1906. Estimated loss of life was 120, higher than in any other U.S. earthquake other than the 1906 San Francisco event. Most of the loss of life was suffered by people being hit by falling debris from building cornices and parapets as they tried to leave shaking buildings. The duration of severe shaking was only about 20 seconds.

Most schools in the area were built of masonry with exterior brick covering hollow clay tile. Roofs and supported floors were wood. The destruction of this type of construction was the most spectacular. Fortunately, the earthquake occurred after school hours and a catastrophic situation was averted. However, the destruction was so extensive that the California legislature passed the "Field Law" on Apr. 10, 1933 requiring all new public schools to be highly earthquake resistant. Structures built under this law have performed  excellently in subsequent shocks.  Fortunately there was no major fire following the quake, but the fire department did suffer severe damage to all its fire stations and fire-alarm systems. The water mains had numerous breaks, most occurring in sand, silt or fill. Water in reservoirs fell dangerously low but never gave out. Ten gas fires were reported during the night of March 10-11, but none resulted in major losses.

One of the most noteworthy earthquake in the U.S. on March 10 occurred as a Mw 6.5 in the Parkfield, California region. Houses were damaged severely along the San Andreas fault zone in Monterey and San Luis Obispo Counties. Chimneys fell at Parkfield and in southern Cholame Valley. One house was jolted from foundations and another was twisted into two parts. A water tank was knowed down on a ranch  and oil pipelines broke  between Shandon and Antelope, CA.  There were 3 breaks in the Producers Transportation Line, one close to a 1934 bread in a nearby oil pipeline.  A ground crack 15-30 cm wide and about 800 m long was observed in Cholame Valley but smaller cracks formed throughout the San Andreas fault zone.  This was the earliest Parkfield shock for which seismograms exist. A comparison of the Berkeley recordings implied that the 1922 epicenter was located 6 km NW of the 1934 epicenter. Later studies suggested that the magnitude of this quake was identical to that of June 8, 1934.

By far the largest earthquake to occur on March 9 occurred in 1957 in the Central Aleutian Islands. This was part of an 28 to 29-year recurrence interval in great earthquakes (see history note from March 7, 2003). Large or great earthquakes have occurred from the Fox Isl. to the Central Andreanoff Islands in the years 1872, 1901, 1929, 1957, and 1986. The largest of these was the event on March 9 which ruptured the Aleutians arc from the Fox Islands to the western Andreanoffs,  a rupture length of more than 1,000 km from 160W to 180W. After a few preliminary shocks in January and February, two of which were important (Ml 6.4 and 6.5 on Jan 2, 1957). The great earthquake occurred on March 9. Over 600 strong aftershocks were recorded including at least 6 of Ms>=7.  It should be noted that the large number of shocks recorded are not, strictly speaking, aftershocks, for the epicenters are spread over a huge area 200 km wide by about 1,000 km long covering the entire central portion of the Aleutians. Thus energy was not released always at the same point, but sometimes at one, sometimes at another, along  the seismic zone.  The mainshock caused a tsunami which spread across the Pacific and reached the Hawaiian Islands and then northern Japan. Thanks to a warning system set up in the United States to prevent a repetition of tsunami catastrophes like the one on 1 April, 1946, the people of Hawaii living along the coast were evacuated in time. However, there was important material damage, approximately $3 million on Oahu and Kauai.  In Japan the waves were about 10 feet (3 meters) high and  submerged several villages on the island of Hokkaido, though fortunately without loss of life. A forty-foot wall of water smashed into the coastline at Scotch Cap, Fox Islands. At Sand Bay, Alaska a 26-foot wave washed away many buildings and did extensive damage to oil lines. At Adak, 15-foot wide cracks appeared in the road and two bridges were destroyed. At Umnak the earthquake destroyed part of the dock, flipping the piling on the  road like matches. A cement mixer was turned upside down and other equipment scattered about. Mount Vsevidof, on Umnak, dormant for 200 years erupted. Other volcanic activity was reported on the  Alaska Peninsula where Mount Trident was observed sending up smoke and steam.

This earthquake measuring Mw 8.6 killed 31 and injured 572. The number of houses destroyed was 713 while nearly 6,000 were damaged. 28 were and warehouses were destroyed in Kushiro. 3 were killed and 309 houses destroyed at Kiratapu.  1,000 houses were destroyed or damaged at Shiranuka and 400 houses  were destroyed at Hamanka. 4 schools collapsed at Sapporo. The earthquake triggered a 10-foot tsunami and was followed by and aftershock of Ms 7.1 on March 9 which injured 17 more and destroyed 113 additional houses. The tsunami affected areas around the Pacific including Crescent City, CA where there was a 36 cm  tsunami recorded. Due to the efficient warning system in Japan at the time, however, no fatalities were caused by the tsunami. The March 4 earthquake off Hokkaido was appears to have begun a chain reaction of great earthquakes in the Kuril chain. This can happen when a segment ruptures, putting strain on the adjoining segments. The following is a quote from "Earthquakes and the Deep structure of the South Kuril Arc" by  S.A. Fedotov, A.M. Badasarova, I.P Kuzin and R.Z. Tarakanov, 1971

NOAA/Dept of Commerce.  "The earthquake of 4 March 1952 marked the beginning of a series of disastrous Kurile-Kamchatka earthquakes in March and November 1952

[Kamchatka Mw 8.3], November 1958 [Mw 8.2 in the next segment of the Kurile arc to the north - the Etorofu quake], May 1959 [Kamchatka Mw 8.0]; and October 1963 [Mw 8.2 in the next segment of the Kuril Arc north of the Etorofu quake]. These were probably interrelated events of a single high-seismicity period." These were the strongest earthquakes in the southern Kurils since 1843. The area has an average interevent occurrence interval of great shocks of about 140 +/- 40 years. At Mw>=7.5, the interval is around 40+/- 5 years. The largest earthquakes off Hokkaido in  1910 (Ms 7.5) then 42 years later in 1952 (Mw 8.6) and then again 42 years later in 1994 (Mw 8.1).

This event, often referred as the great Sanriki earthquake and tsunami killed more than 3,000 people and caused severe damage throughout the region of the northeast coastline of Honshu. A giant tsunami was  triggered by the earthquake which occurred offshore in the trench. The Bulletin of the Earthquake Research Institute, University of Tokyo published an entire volumne on the earthquake and tsunami (Suppl. Vol. 1, March 1934).  Some interesting observations were also made relating to earthquake and tsunami lights during this event (see above).

This event, often referred as the great Sanriki earthquake and tsunami killed more than 3,000 people and caused severe damage throughout the region of the northeast coastline of Honshu. A giant tsunami was  triggered by the earthquake which occurred offshore in the trench. The Bulletin of the Earthquake Research Institute, University of Tokyo published an entire volume on the earthquake and tsunami (Suppl. Vol. 1, March 1934).  Some interesting observations were also made relating to earthquake and tsunami lights during this event (see above).

One of the largest earthquakes to be recorded in Ohio. Damage occurred in western Ohio near Anna county consisting of fallen chimneys and plaster and cracked walls.  The public school at Anna was  damaged so badly it was declared unsafe. Two churches also sustained damage. Plaster fell in buildings as far away as Indianapolis, IN and Fort Wayne, IN. The shock was felt in Indiana, Kentucky, Michigan, and West Virginia and Ontario, Canada. An aftershock occurred on March 9 which was larger than the March 2 event. This later event further damaged the schoolhouse and churches in Anna, OH.  These events caused some wells to go dry and to increase the flow of water in other wells - water, oil and gas. This shock was felt from Chicago to Toronto and from Missouri to West Virginia (Ms 5.5).
