地电阻率趋势异常与应力场的相关性分析
Correlation analysis between the trend anomaly of the earth resistivity and the stress field
摘要
Abstract
A total of 26 ground resistivity stations with significant annual variation periods were selected and calculated by multiple linear regression.It is concluded that the influence of temperature on the annual period of ground resistivity is the largest among the meteorological factors of most stations,followed by groundwater,temperature,and rainfall.By using the Fourier method to eliminate the influence of the annual cycle,and then by removing some data that still have a linear relationship with rainfall,the obtained abnormal changes of ground resistivity can be well correlated with the changes of the stress field.Among them,the abnormal synchronization information between near stations and the abnormal changes of multiple stations in a wide area are related to the changes of the stress field(or earthquake situation).The local anomaly changes can reflect the moderate seismic anomaly signals in the area,while the wide anomaly changes are related to the subduction activities on the northwest margin of the eastern Pacific plate,so they are related to the occurrence of Japanese earthquakes.关键词
