Variation of apparent stress of Qianguo strong earthquake swarm in 2013
摘要
Abstract
Seismic data of small to moderate earthquakes recorded by Jilin Seismic Network and its neighborhood from September 10th to December 24th,2013 are selected. On the basis of the assumption that source displacement spectra accords with Brune model,apparent stress values of 33 earthquakes(2.0≤MS≤4.9) before and after MS 5.8 have been calculated. The result shows that the apparent stress before MS 5.8 earthquake had an obviously increasing process. Then it declined when reaching maximum value. MS 5.8 earthquake occurred during the apparent stress was coming down. After MS 5.8 earthquake,the apparent stress was at a low level.关键词
