The great Tokyo earthquake. This event caused up to $3 billion (U.S. Dollars) damage. More than 142,000 were killed. A tsunami was generated. This earthquake is usually referred to as the Kwanto earthquake. Up to 38,000 residents of Tokyo were burned to death in an open area where they had congregated following the earthquake for safety. The firestorm which followed the quake destroyed libraries, museums, at collections, archives and scientific data among other irreplaceable structures and items. The earthquake was located in Sagami Bay southwest of Tokyo. At least 15 lines of vertical faults were found with displacement up to 6 feet. Leveling showed uplifts up to 2 meters along the Sagami Bay. The tsunami reached up to 10 meters. Many groundwater effects were observed including pulsating earthquake fountains. More than 128,000 houses were destroyed in the quake and up to 450,000 were burned in the ensuing fire. A hotel built one year earlier with great ability to move (architect: Frank Lloyd Wright) survived with only a few cracks and was used as hospital and first aid station following the earthquake. Building techniques in Tokyo contributed to the firestorm. These included building close to the ground and paper thin walls

The Charleston, South Carolina earthquake. Up to 60 killed $5 million damage but probably much more. Maximum intensity IX. This earthquake was preceded by four days of small foreshocks which began immediately after an M 8.4 in central Greece. That earthquake may have disturbed the groundwater sufficiently to lubricate the fault responsible for the for the Charleston quakes ultimately triggering the strong event. The mainshock started with an audible noise which gradually became louder to a roar. As the roar began all objects began to shake. This shaking accelerated and frightened many. The initial shock caused many to gather in public places and was followed eight minutes later by a second shock. Further aftershocks continued and further damaged buildings. Railroads and telegraphs were damaged although many fled the area. A tsunami was generated which was observed in Jacksonville, Florida and on the Cooper River. Sulfur gas was evident in the Charleston area. Because much of Charleston was built on landfill liquefaction, amplified shaking and sand blows were all very evident. Chimneys of more than 14,000 homes fell. Three-story buildings showed damage to second story and at the top (this same phenomena caused by the wavelength of vertical waves moving upward through the building was observed in the Kobe, Japan quake of 1995). Wooden buildings fared better than stone. Apparently there were two epicenters for this event - one near Woodstock northwest of Charleston and the other due west of Charleston. Fissures were common in the ground and water extruded from cracks in some cases in high jets. Rails were bent. The quake was felt over an area of more than 1300 km - up to about 2 million square miles. Severe damage occurred at Savannah and Columbia, S.C. Some damage occurred at Augusta, Raleigh, N.C. and Wilmington, N.C. Also felt in Boston, MA, Milwaukee, Wis and Cuba. Felt strongly at New York City. An strong unnamed hurricane passed offshore Charleston on August 24, 1886.

Earthquake in the Amuri District of North Canterbury north of Christchurch, New Zealand. This quake ruptured the Hope Fault and caused widespread damage to buildings. Maximum intensity was up to IX. Offsets of between 1.6 and 2.4 meters were observed. The earthquake may have been triggered by the event in the South Kermadec Islands 35 minutes earlier.

12,000-15,000 killed with maximum intensity X at Dasht-e-Biaz, Iran. Known as the Dasht-e Bayaxz earthquake. Disastrous in Khorasan. Many villages were completely destroyed over an area of 4,000 sq. km. 12,000 homes destroyed and more than 70,000 people were left homeless. At Dasht-e Bayaz 3,000 of the 3,500 population were killed most buried under the ruins. Mosques and other public buildings were also destroyed. Two mosques up to 300 years old were destroyed. Adobe houses were almost all completely destroyed however brick buildings held up much better. The main destruction occurred along the fault line which was up to 300 meters in places but damage occurred for tens of km from the fault.

Chimneys fell and oil tanks collapsed in Terrace. Cars were moved about on the road. At Delkatla, the bridge "writhed like a snake" and the ground was cracked. Horses in the epicentral area became restless up to an hour before the quake and could not be controlled. One crack across the Delkatla Slough was 50 feet long and 6 inches across and the bottom could not be located. Trees were felled in the epicentral area. At Prince George alarmed people ran into the steets. The event was felt from Portland, OR to Jaspar, Alberta, Canada. An area of more than 2 million square miles was affected. As the surface waves passed Ottawa more than 3500 km distant astronomers were unable to use telescopes as the shaking was too great. A surveyor in the Arctic reported he could not find his position as the cross hairs in his telescope could not be held steady.

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.

8 17 0 40 0 1906 -33.000 -72.000 60 8.6 Central Chile

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 about 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.

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.

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.

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.

This 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 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.

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 the 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 additional 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.

May relate to an earthquake later confirmed in the Kii, Nankaido area on Sept. 20, 1498. That quake generated waves recorded at Ise, Mikawa and Izu. Milne says the event was felt throughout Japan with intensity VII-X. Iida was unable to confirm this from local records and believes the tsunami attributed to an event on July 8 is the same as that from Sept. 20. There does appear to have been a strong earthquake in Kyoto on July 8 however.

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.

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.

Earthquake at Parkfield, this was the last in the supposed 22-year cycle of earthquakes that was expected by some to recur in 1988, but may have been delayed by the Coalinga earthquakes in 1983. This event was preceded by an M 5.0 foreshock. It reached intensity VII and showed minor surface faulting along the San Andreas Fault zone. About a mile north of Cholame pavement cracked on Highway 466 and the dividing line was offset by 4 inches. Minor damage was done to bridges in the epicentral area. Tombstones overturned in Parkfield and seiche was observed in pools and water tanks.

June 28, 2004 is the 12th Anniversary of the Landers/Big Bear earthquake in Southern California which occurred in 1992. This event is often considered a landmark event in that strong triggering was observed for nearly 1000 km from the epicenter, especially in volcanic regions. This caused many geophysicists to rethink the prevailing paradigm that earthquakes had no effect at distances more than several fault lengths away from the epicenter.

The second strong damaging earthquake to occur in the Baikal region on this date, this event caused subsidence of 5-6 meters in the Namarakit trough. Seismic dislocations cover an area over 30 km with fissures up to 19 meters wide and 4 meters in height. Other structures such as twisted folds, seismic domes, shear fissures etc. were observed. Changes in underground water occurred at high large distances. Local hot springs as far as 180 km from the epicenter increased temperature by about 5 degrees Celsius. Under ground water levels rose about 2 meters in the city of Chitka and flow nearly doubled.

The earthquake occurred in a relatively unpopulated area. At the nearest settlements, about 50 km to the west in Bezymyannyy stoves and chimneys were destroyed. In the city of Bodayho about 250 km from the epicenter cracks and ruin of chimneys and stoves occurred. As far away as 500 km plaster cracked and cracks appeared in buildings (at Chitka).
