| Abstract: | Short-term and imminent earthquake anomaly variation appeared in crustal tilt and ground strain data before the MS≥4.0 earthquakes in Shanxi and the MS≥7.0 earthquakes at home and aboard are studied by using the routine analysis methods of yearly variation and vector graph.Time from anomaly starting to earthquake occurring,anomaly lasting time,time from anomaly ending to earthquake occurring and anomaly shape etc.are calculated.Through the first order differential analysis on the daily mean values of crustal tilt and ground strain data of Shanxi.Based on anatomy of typical earthquake events,short-term and imminent earthquake anomaly characteristics of crustal tilt and ground strain before the MS≥4.0 earthquakes in Shanxi(near field) and the MS≥7.0 earthquakes in far field are figured out. |
| Keywords: | Seismostation record characteristic rapid earthquake report |
