2010年河津MS 4.8地震前后单台波速比变化特征分析
Temporal variation of vP/vS at single seismic station before and after Hejin MS 4.8 earthquake in the year 2010
摘要
Abstract
Based on the seismic phase report of Shanxi Province from January 2001 to October 2014, the variation of wave velocity ratio before and after Hejin MS 4.8 earthquake in the year 2010 is analyzed by using Wadati method of single station and multi-earthquake in this paper. And four stations,those with relatively continuous seismic phase data,were selected. The results showed that the middle wave velocity ratio displayed anomaly for two or three years at Linfen Seismic Station and Anze Seismic Station,which are situated in the northern side of Hejin MS 4.8 earthquake’s epicenter. At the same time,the different azimuthal partition result indicated that, the wave velocity ratio curve,which represented southwest of Linfen Seismic Station and south of Xixian Seismic Station,showed short period anomaly before Hejin MS 4.8 earthquake. The abnormity had obvious relationship with scope of earthquake pregnancy,the better ray the station accepted,the more obvious anomaly was showed.关键词
