【摘要】 采用地磁短周期日变之低点位移方法和加卸载响应比法,分析了广东东源县2012~2013年间三次MS4.0~4.8级地震的震磁响应,发现震前震中周边台站均存在有不同程度的低点位移异常和加卸载响应比异常情况。更多还原

【Abstract】 By utilizing low displacement method and LURR method of the earth short cycle diurnal variation,the paper analyzes the seismomagnetic of 3 MS4.0 ~4.8 earthquakes during 2012 to 2013 in Dongyuan of Guangdong province, The results show that there existed different levels of low-value displacement anomalies and unload response ratio anomalies before the earthquake epicenter surrounding stations.更多还原
