Research on Regional Deformation Anomalies before the Wen'an Ms5.1 Earthquake
摘要
Abstract
Using the rigid-linear elastic model to fit 2001 2004 GPS regional velocity field and strain rate field,we obtain 1 3 years precursory anomalies before the July 4th,2006 Wen'an MS5.1 earthquake.The results show that the earthquake occurred in the anomaly area and the edge gradient transition zone of the high abnormal body.关键词
