1997 Jiashi earthquakes


The Jiashi earthquakes were a series of earthquakes from 1997 to 2003, with several earthquakes larger than 6 occurring between January and April, 1997. Two strong earthquakes with magnitudes 6.4 and 6.3 occurred on January 21, 1997, at 09:47 and 09:48 local time, respectively, in Jiashi County of Xinjiang Autonomous Region, NW China. The earthquakes occurred on a major strike-slip fault beneath the Tarim Basin. The fault has no surface expression and prior to the earthquake was not known about. At least 12 people were killed and 40 injured in the earthquakes of January 21. Another earthquake on March 1, 1997, at 14:04 local time with magnitude 6.0 killed another person. On April 6, 6, 11, 16, other four earthquakes with magnitudes 6.3, 6.4, 6.6, 6.3 killed 8 people. Several predictions were made in this earthquake series. Some of the predictions were not fulfilled, while some preceded the predicted earthquake from 2.5 hours to 4 days. The April 11 earthquake occurred 30 minutes after a prediction was made.
