Registering a surface-wave magnitude of 6.8, the earthquake killed about 150 people and injured roughly 300 more. It caused comprehensive damage within close range of its epicenter. Background China has an extensive history of catastrophic earthquakes that ranges back to 1290. The first verified earthquake took place in Chih-li, killing roughly 100,000 people. The next great earthquake was probably the 1556 Shaanxi earthquake, the most devastating earthquake of all time. Roughly 830,000 were killed by the event. Other earthquakes in 1917, 1918, 1920, 1923, 1925, 1927, 1931, 1932, 1933, 1948, 1950, 1966, 1969, 1970, 1974, 1975, 1976 each killed at least one thousand people. Since 1981, earthquake fatalities have diminished greatly, though have not been stopped. As recently as 2008, an earthquake in Sichuan killed nearly 90,000 people.https://earthquake.usgs.gov/earthquakes/world/historical_country.php#china Historic World Earthquakes – China United States Geological Survey 23 November 2009 22 January 2010 dead https://web.archive.org/web/20100728221758/http://earthquake.usgs.gov/earthquakes/world/historical_country.php 28 July 2010 Characteristics The epicenter was pinpointed to Dawu County in Sichuan. Its official magnitude was 6.8 and its surface wave magnitude reached 6.6.https://earthquake.usgs.gov/earthquakes/eqarchives/significant/sig_1981.php Significant Earthquakes of the World – 1981 United States Geological Survey 5 January 2010 22 December 2010 dead https://web.archive.org/web/20121011191203/http://earthquake.usgs.gov/earthquakes/eqarchives/significant/sig_1981.php 11 October 2012 A moderately well controlled focal mechanism indicates that the earthquake was probably a result of left lateral strike-slip faulting on the Daofu fault. The Daofu fault forms part of the Xianshuihe fault system, which experienced a sequence of four earthquakes greater than 6.0 between 1973 and 1982, with each event triggering the next in the sequence by changing the stress state.Zhang Q.
