Analysis on the small earthquake cluster in Helingeer with apparent stress method
摘要
Abstract
Acccording to the earthquake cluster, which appeared in Helingeer, Inner Mongolia autonomous region on October 29, 2015, the earthquakes of ML 2.0 occurred in Helingeer area during March 2010 to December 2015 are studied. Using the inversion of digital seismic waveform data for source parameters of the time frame, adopting the nearby Brune mode, the spatial and temporal variations of stress in the region are rendered. The results show: ① Apparent stress value is relatively low in the studying area; ② The temporal variation of apparent stress in region of small earthquakes occurred frequently has no obvious relationship with earthquake occurrence;③ There is an asynchronous variation rule between the temporal distributions of apparent stress and magnitude of small earthquake cluster in Helingeer.关键词
