The abnormal change of cave volume strain for Minxian - Zhangxian MS 6.6 earthquake
摘要
Abstract
In this paper,the anomalous variation of cave volume strain data at Dangchang Seismic Station is analyzed. The result suggests that the data has recorded the whole process of earthquake deformation. The process is: interseismic deformation,then,preseismic deformation (which include the acceleration period and unstable period),then,coseismic deformation,then, postseismic deformation (which include the post seismic slip and the adjustment),and last, interseismic deformation. The post seismic slip of long duration is extremely rare in our country, so this data is extremely valuable for the study of earthquake gestation process.关键词
