绥化台地电阻率异常与震兆特征
|
摘要
以绥化地震台地电阻率8年的地震观测资料为参考依据,研究了台站周边300km范围内的5级以上地震和200km的4级以上地震,对地电阻率资料异常形态与地震关系进行了探讨。结果显示,其异常形态表现为多年趋势下降变化异常、年变的消失、震荡异常、台阶等,其正常年变形态为正弦波形的变化,异常与地震对应关系良好。
Based on the 8 years observation data of ground resistivity,ML>5 earthquakes 300km and ML>4 earthquakes 200km away from Suihua Seismic Station have been studied.The relationship between anomalous modality of ground resistivity data and earthquake is discussed.The results indicate that the anomalous modalities are represented as decreasing trend for years,annual variation disappearance,oscillation anomaly and step changes.The normal modality is represented as the sine-wave variation.It has a good corresponding relation between anomaly and earthquake.
