粤闽赣交界地区地震活动若干特征及其地震大形势分析

Characteristics of the seismicity and analysis of earthquake situation in the border area of Guangdong,Fujian and Jiangxi

运用地震地质、地震活动时空分布、地震能量及其量值空间扫描、地震条带、小震频次、数理统计、地震迁移等方法 ,研究了粤闽赣交界地区地震活动特征 ,并作了地震趋势分析 ,认为研究区第四活动幕已临结束 ,近十年内发生 6级以上地震可能性很小 ,发生

In this paper,based on the methods of the seismogeology,space-time distribution of seismicity, earthquake energy,the space scanning for earthquake energy value, seismicity belt, the small earthquake frequency, mathematical statistics, earthquake migration and so on, we studied the characteristics of the seismicity in the border area of Guangdong, Fujian and Jiangxi, and analyzed the general earthquake situation. We considered that the forth seismic active screen of the researched region is over, and the probability of an earthquake with M≥6 0 is small in the coming ten years, the probability of an earthquake with M S≥5 0 is small too.
