粤桂琼交界地区地震趋势综合分析

Synthetical analysis on earthquake tendency in the juncture area of Guangdong,Guangxi and Hainan

应用地震活动、台站前兆观测、流动重力、海平面变化和统计分析等多种方法 ,综合分析了粤桂琼交界地区近期的地震活动趋势 ,认为近 3年内或稍长一些时间 ,该区发生 6级以上地震的可能性很小 ,但有可能发生 5级左右地震。

In this paper, by using the methods of the seismicity,precursor observation, mobile gravity, sea level change,statistical analysis and so on, the recent earthquake tendency in the juncture area of Guangdong, Guangxi and Hainan is analyzed synthetically. It is considered that the probability of a earthquake with M≥6 0 occurred here is lower in three years or same as longer, but there is possibility of earthquake occurred with M≥5 0 or so.
