新疆钻孔应变对汶川8.0和日本9.0级地震的同震响应特征分析

Characteristics Analysis on Coseismic Response of Borehole Strain in Xinjiang to Wenchuan M_S8.0 Earthquake and Japan M_S9.0 Earthquake

初步分析了新疆钻孔应变台站体应变在汶川8.0级、日本9.0级地震前后的变化特征,结果表明:体应变与远大地震同震响应和震中距关系不大,而与钻孔所处的构造位置、台站岩性等因素有关。

This paper analyses the characteristics of coseismic response of borehole strin in Xinjiang to Wenchuan Ms8.0 earthquake and Japan Ms9.0 earthquake. The result indicates that the coseismic response of borehole strain in Xinjiang does＇t correlate with epicenter distance, but relates to tectonic position and lithology of the borehole.
