7 28 6 40 0 1913 -16.600 -73.300 30 7.0 So. Peru/Bolivia

Submarine cables were snapped along the coast about 500 km to the southwest of the epicenter, probably by underwater slides. The earthquake was felt along the coast of Chala and Mollendo.

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 deat toll in an earthquake in the past four centuries and the second greatest ever recorded.

7 28 17 22 25 1981 30.013 57.794 33 7.3 So. Iran

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.

7 27 19 42 55 1976 39.570 117.978 23 8.0 So. China

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.

Felt over an area of about 500 km radius. Little damage occurred near the epicenter because of its remote and uninhabited nature. The following information is from the article by E.H. Bramhall in the Bulletin of Seismological Society of America, Vol. 28 No 2, April 1938 "The Central Alaska Earthquake of July 22, 1937". At Salcha Bluff the highway was blocked by a large landslide. Mud boils and long cracks were observed in this area more than a foot long. Water was well above normal. A two-story log structure was destroyed in the earthquake. Fairbanks also suffered damage. Estimated damage in Fairbanks was $5000 and included damage to bottles, windows and other goods. Infrastructure was undamaged. Felt from Anchorage to Valdez and along the Alaska Railroad.

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.

While not strictly s significant earthquake in the sense required for inclusion in this listing one of the largest earthquakes to ever hit Britain occurred 20 years ago today. This quake hit North Wales hit early on the morning of July 19, 1984 with M 5.4. It was the largest event in the UK in the 20th century and was felt over an area of about 250,000 sq. km (nearly all of the United Kingdom). Much of North and mid Wales was strongly shaken Electricity went out, stone walls fell, animals stampeded and the gables of houses fell. Damage was mitigated by strict building codes in the region. The seismic history of England has been recorded for nearly 2,000 years and a number of damaging events have occurred during in that time.

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 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.

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.

7 8 9 45 0 1730 -33.000 -72.000 0 8.5 Central Chile

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.
