摘要
将山西临汾中心地震台在四川汶川8.0级地震前地倾斜形变观测的原始记录图、日均值图、矢量图中存在的地震扰动、同震阶跃等异常形态进行分析。以发现震前的中长期异常,总结规律,提高地震预测水平。
In order to find mid-long term anomalies before earthquakes,summarize the rules and enhance earthquake prediction level,the anomalous shape,such as earthquake disturbance and coseismic steps in original record,daily mean value and vector curves of ground tile observation at Linfen Central Seismological Station before Wenchuan,Sichuan M8.0 earthquake are analyzed in this paper.
