摘要
利用MapSIS软件[1]编制地震震中分布图、M-t图、频度图、活动性参数扫描,台湾强震与赣南及邻区、闽粤沿海地区中强地震对应统计对赣南及邻区地震活动特征进行了分析,认为该区域中强地震的发生需经历微震或有感地震活动增强过程,且中强地震发生具有与台湾地区、巴士系断裂带强震同步活动的特征,未来1～3年具备发生5级左右地震的条件,发生6级以上地震的可能性不大.
The paper uses MapSIS to draw up software for earthquake epicenter distribution map, M-t map, frequency diagram and activity parameter scanning, and the corresponding statistics of strong earthquakes in Taiwan and moderately strong earthquakes in Fujian and Guangdong coastal area are used to analyze the earthquake activity characteristics of Gannan and nearby area. This area can experience moderately strong earthquake after the micro seismic or sensible seismicity, meanwhile the characteristics of the earthquake are similar to that happened in fault zone of the Bashi lines and Taiwan Region. The condition of earthquake occurrence with level 5 in 1 to 3 years is equipped, and there is no large possibility for the earthquake above magnitude 6.
