 8 19  5 33 30 1961  36.017  136.767  17 7.3   No. Honshu, Japan

 

This earthquake known as the Kita Mino earthquake occurred in an area known for destructive earthquakes. The epicenter was located in the Haku-San National Park. 9 killed and 36 injured most from falling rocks. The earthquake was  followed by many aftershocks. An unusual distribution of first motions for this earthquake does not follow the normal pattern and the nature of this shock is questionable. It is very likely that this is a classic example of a large shock triggered by a seismic wave from another strong earthquake. The timing between the Peru event and the succeeding Honshu quake is 23 min. 40 sec. The distance between these events is 144 degrees. A core reflection from Peru (PKS or SKP) would have arrived at the Honshu epicenter within  10-15 seconds of the initiation of the rupture in Japan. It seems likely that this phase initiated the deadly earthquake in Honshu.

Known as the great Valparaiso Earthquake. This was the first fully  documented Chilean quake from the modern point of view. The epicenter was near Valparaiso and maximum intensity IX-X extended to the north for several hundred km in which area considerable damage occurred (from Papudo and eastward to Tiltil and Melipilla. Santiago felt the quake with intensity VIII. Two ships offshore were damaged by the seaquake (shaking at sea from an earthquake). On the S.S. Thuringa gangway plates were thrown in the air and damage and leaking from the hull was found. A 50-ton crane fell over and narrowly missed the docked ship. On the S.S. Varda it was feared the ship would break in two and lifeboats were released. Pipes broke and water flooded the engine room but the anchor was not lost. The lower part of Valparaiso was largely destroyed probably due to its location on landfill. A fire followed and destroyed much of the city built on hillsides. A tsunami followed with maximum amplitude of 2-3 feet. A tsunami in Japan was probably the result of the Andreanof Islands earthquake which occurred half an hour earlier. Coastal uplift occurred up to abou 1 meter especially at Valparaiso but the uplift was not permanent and later subsided. Felt throughout much of South America from off the eastern Seaboard (aboard a ship off the Atlantic coast of Patagonia) to Buenos Aires, the Juan Fernandez Islands and Peru.

Aftershock of strong and damaging earthquake in Mindanao on Aug. 16 which left up to 6000 dead and 90,000 homeless. Additional damage was reported but was mixed with the damage from Aug. 16. Following is a summary of that event.

 

This earthquake in Mindanao, Philippines occurred about 1000 km south of Manila. The quake killed more than 1,200 leaving thousands homeless. Many government and private buildings and bridges collapsed or suffered extensive damage. The province of Lanao del Sur was the hardest hit. More than 175 were killed in Balabagan town. In Paraadian City 30 were killed and more than 100 families left homeless. At Davao nearly 1000 were reported killed in collapsed houses and buildings. Damage was also extensive at Cotabato City. Notre Dame University was extensively damaged. The quake was followed by a strong tsunami with maximum amplitude up to 15 feet at Lanao del Sur. This tsunami and swept many out to sea while destroying wharves and housing. Liquefaction was common and subsidence caused a market in Lebak to  sink half a foot. Ground water changes were common.

This was one of the most widely investigated earthquakes in South America. Damage occurred throughout southern Peru and northern Chile from Guayaquil  on the north to Valparaiso on the south. About 150 were killed in Moquequa alone and 3000 in the region of Arequipa but the total number of deaths ranged from several hundred to an estimated 40,000. Many of the dead were killed by the tsunami while seeking protection from the earthquake at sea walls. Arequipa, Moquegua, Mollendo, Ilo and Arica and other villages and towns in the area were largely destroyed. A tsunami was generated which was observed throughout the Pacific Ocean and did damage in New Zealand, Australia, Samoa, Hawaii, California and Japan.  At Isla,Peru the sea withdrew suddenly and after a delay of 20 minutes in Arica the first wave reach with maximum height up to 17 meters. This tsunami destroyed what was left of Arica. The third or fourth wave was the highest and was described as a wall of water up to 45 feet high. This wave carried several ships as much as three miles inland where they lay for more than

50 years afterwards. A series of foreshocks preceded the earthquake. Cracks formed near Arica which were 5-8 cm wide and issued flows of mud, water and asphyxiating gasses. The air was charged with electricity such that sparks were observed when fingers were run through dry hair. Earthquake lights were observed throughout the Andes as moving balls of light. Waves could be seen passing over the surface of the earth.

 7 28  8 40 10 1957  17.110  -99.100   0 7.7   Oaxaca, Mexico

 

This earthquake was highly destructive in Guerrero and in Mexico City. It was felt over an area of up to 30,000 sq. km. with the most affected area in San Marcos. But damage also occurred  in Jaltipan, Coatzacoalcos, Acayucan and in the area  of the Isthmus of Tehuantepec. 57 were reported killed (46 in Mexico City) and more than 400 injured with thousands left homeless. At San Marcos and Chilpancingo 90-95% of the houses were destroyed. A small tsunamis was generated and  recorded in the Aculpulco Bay area.  This was the strongest earthquake to hit Mexico City since June 7, 1911. Damages were estimated up to $11 million (U.S. Dollars). In Mexico City about 40 large buildings collapsed. While the epicenter was more than 300 km away, this  is typical damage in Mexico City due to the situation of Mexico City in an alluvial valley which amplifies accelerations up to five times normal.

 

 7 28 10 45 35 1976  39.664  118.401  26 7.4   So. China

 

This was a strong aftershock of the Tangshan earthquake of July 27, 1976.  That was one of the most deadly earthquakes ever recorded. Known as the Tangshan earthquake up to 655,000 were reported killed, many interred in mass graves. Nearly 800,000 were reported injured in the earthquake and an  additional 500,000 left homeless. Estimated costs were $5 billion U.S. Dollars. The official tolls are much lower (242,000) so the exact toll will probably never be known. Virtually the entire city of Tangshan was destroyed but was damaging throughout northeastern China including at Beijing.. This is the greatest death toll in an earthquake in the past four centuries and the second greatest ever recorded.

Known and the Kernan earthquake, this event occurred in Southwestern Iran and did extensive damage in the Kernan area including the death of 1500. At least 1000 were also injured and 50,000 left homeless when the many villages around the Kernan area were completely destroyed. The Kernan area was hit by strong foreshock on June 11, 1981 when an M 6.7 killed 3,000 people and injured many more.

Nearly 800,000 were reported injured in the earthquake and an  additional 500,000 left homeless. Estimated costs were $5 billion U.S. Dollars. The official tolls are much lower (242,000) so the exact toll will probably never be known. Virtually the entire city of Tangshan was destroyed but the earthquake was damaging throughout northeastern China including at Beijing. This is the greatest death toll in an earthquake in the past four centuries and the second greatest ever recorded. Tangshan has now been completely rebuilt and is home to steel and mining industries today. At the time Mao Tse-tung became gravely ill and died two months later. Many see the earthquake as an omen for his death and the end of an era. There has been controversy whether a warning from local scientists was taken seriously prior to this earthquake. At Qianlong County 70 km from Tangshan there were few fatalities even though thousands of buildings were flattened. Officials had heeded warnings from local  seismologists and ordered people to work and sleep outside minimizing casualties when the earthquake struck.

Severe damage occurred at Modurnu and Adapazari, Turkey with maximum intensity up to X. This earthquake was felt over an area of 500,000 sq. km.   More than 170 (official toll was 173) were killed, 107 severely injured, 76 more were slightly injured. more than 4000 homes were destroyed or  uninhabitable an additional 5000 were damage. The damage was greatest near Adapazari. The event occurred on the westward extension of the same fault which caused the earthquakes in Bolu in 1944 and in Abant in 1957. Ground cracks and displacement were visible for more than 70 km reaching up to 1.4 meters horizontal displacement and up to 1.3 meters vertical throw. Damage near the fault was less than that at some distance from the fault. This is a common observation in many large earthquakes. Another common observation is that the wood frame houses held up well compared with those made from Concrete. A strong aftershock sequence followed. Many effects were similar to those seen in the Izmit earthquake of August, 1999.

This earthquake was highly destructive in the Lima, Peru area. Lima was mostly destroyed and teh towers of the cathedral collapsed. The event was preceded by ominous rumbles which caused the residents to run from their homes saving most, but between 14 and 22 were killed by falling homes. Damage was also recorded in Callao, Chancau, Ica and Cusco.  A tsunami was generated. The sea came in fourteen fathoms (26 meters) high immediately after the shock and inundated the country for two leagues (10 km) from the shore. The tsunami was also observed in Tokura, Japan where it reached a height of 1-2 meters.

This earthquake was destructive in the Gulf of Izmit near the same epicenter as the earthquake of August 1999 which killed nearly 20,000. The most severe damage was in the areas of Istanbul, Adapazari and Katirli where  83 were killed. An addition 990 were killed in the Sapanca area including 276 killed by falling buildings and other construction. Three dams providing water to Istanbul were badly damaged. Mud volcanoes were observed on the  Sakarya river. Most surrounding villages were totally destroyed and liquefaction was common along with landslides in the epicentral area. A tsunami was generated which had maximum height of 1.5 meters.

The New Catalog of Strong Earthquakes in the U.S.S.R. (1982) says that in an instant all the buildings in Khaft were destroyed. There were great landslides and the dust caused the entire area to grow dark. Trees were tossed to the ground. A car on the road had passengers flung from the vehicle. Nearly all construction was destroyed in the epicentral region for about 70 km along the fault that ruptured. Maximum intensity of IX to X was reached in the mountains. An avalanche along the Yasman River had a length of about 20 km and a width of over 1 km. The number killed was probably in the thousands although no official totals were published at the time.

 

 7 10  6 15 51 1958  58.600 -137.100   0 7.9   Southeast Alaska

 

One of the strongest shocks in Alaska during the 20th Century. The only settled region was that of Yakutat and effects there were relatively minor. Three were killed on Khantaak Island. One of the largest tsunamis ever recorded was caused by a massive rockslide that hit Lituya Bay causing water to surge up the sides of the bay up to 1800 feet. A gravity wave then swept out to sea killing at least two. At Yakutat cabins, bridges, docks and oil lines were damaged and a water tower fell.  In the mountains trees were uprooted, and large landslides occurred. In the coastal plain sand blows and fissures were observed. Underwater cable breaks were common.

Thought to be the greatest earthquake recorded in Chile by some writers. Santiago was nearly completely destroyed. Concepcion was completely destroyed by a tsunami. The mainshock was followed by a series of foreshocks which began about 4 hours before the mainshock and did little damage but caused residents to spend the rest of the night outdoors. As a result only two persons were killed in Santiago by the earthquake. The ensuing tsunami caused destruction of homes even on hillsides which destroying the entire lower city of Valparaiso. Some destruction from the tsunami was located  as far away as Japan where damage occurred to rice fields in Ojika peninsula.

 7  1  7 50 55 1941  34.367 -119.583   0 5.9   So. California

 

Earthquake in Santa Barbara and Carpinteria with total damage up to about $100,000. Much of this was to drug- and liquor store inventory and to  plate glass. Slide covered the railroad east of Santa Barbara on Rt. 101. Telephone service was out. Most stores in Santa Barbara suffered interior damage in this late night earthquake. Sidewalks, cornices and plaster broke and water mains were common. The Santa Barbara area has a very interesting history of earthquakes over the past century. During the period 1900-2004 six earthquakes of M>5.0 were located in the Santa Barbara area (34-34.5N 119.5-120W). Of these the four that occurred in the first 75 years of the century all occurred between June 29 and July 5 (June 29, 1925 (M 6.3); June 29, 1926 (M 5.5); July 1, 1941 (M 6.0); June 29, 1968 (M:5.1); July 5, 1968 (M:5.7). The only such event not occurring in this time frame in the Santa Barbara area in the past century occurred on August 13, 1978 with M 5.4. Several factors may influence this pattern, but in determining local risk, this type of data is vital.
