唐山4.8级地震前易县地震台地应变异常特征
The abnormal characteristics of the earth train at Yixian Seismic Station before TangshanMS4.8 earthquake
摘要
Abstract
AMS 4.8 earthquake occurred in Tangshan, Hebei Province on May 28, 2012. The earth train observation at Yixian Seismic Station are abnormal, which include the observation of the four component strain, the body strain and the expansion meter. The reliability of these data is verified. The basic situation of abnormal is introduced. The common features of the anomalies are summarized from the abnormal form, the abnormal start and the duration, the abnormal amplitude, the earthquake moment and so on. The analysis shows that the anomaly has the consistency of time and form, and the different observation means of same station at the same time all detect the anomaly, and show that the anomaly has the reliability.关键词
