摘要
Abstract
We analysis the anomaly curve of YRY-4 borehole strain observation in Dunhua Seismic Station on September 10, 2010. Eliminating the possibility to been caused by the abnormal interference,it is comfirmed that the anomaly is the true reflection of tectonic activity in Dunhua area. The analysis suggests that this anomaly is the true reflection of the squeeze of Pacific plate and Eurasian plate during the seismogenic process in the 9. 0 earthquake near east coast of Japan on 13 : 46:21, March 3,2011.关键词
