摘要
Based on seismic data of the regional seismic network for recent 38 years, this paper mapped the b-value in the border and offshore areas of Guangdong and Fujian Province by the means of spatial scanning, and discussed current activity characteristics for various segments of the Binhai fault zone and Rongjiang-Hanjiang fault system with the method of calculating and analyzing of multiple-seismicity-parameter-value combinations. The results show that: 1) the spatial distribution of b-value displaces significant spatial heterogeneity in the studied areas,the average b-value is 0.98; 2) the Dongshan-Zhangpu segment of the south Binhai fault zone is in the relatively high stress area,and it may be the potential seismic sources for large earthquakes in the near future; and 3) the stress accumulating segment was not arouse in Rongjiang-Hangjiang fault system.
