S波分裂在皖北地震中的研究应用
S wave splitting in earthquake research and application in Anhui northern area
摘要
Abstract
Using the basic theory and calculation method of S-wave splitting method, the digital waveform data of ML≥2. 0 local earthquakes occurred in a region surround Lixin Zhang village within 25 km, where is representative in northern Anhui region, which recorded by Mengcheng Seismic Station from its officially operating in 1999 to Sep 2010, are processed. The S wave polarization direction and delay time in different time are obtained. The results provide valuable geophysical information for the study on seismic activity and stress activity state in northern Anhui region.关键词
