摘要
东南沿海地震带可被划分为 4条次级的NE向地震活动带 ,分别为滨海、汕头 -惠来、河源 -阳江和吴川 -四会等地震带。分析了这些地震带上MS≥ 4 3/ 4级地震的迁移方向和速率 ,发现地震沿带的主体NE方向作定向或往返迁移 ,但各带迁移路线和速率各异 ,这可能与断裂活动的均匀性、差异性和构造应力作用方式有关。
The South-East China coastal seismic zone may be divided into four seismic belts in strike of NE such as Binghai,Shantou Huilai,Heyan Yangjing and Wuchuan Sihui.Based on the analysis of the migration direction and rate of earthquake with M S≥4 3/ 4 in those belts,it is found out that the migration direction of earthquakes along the belts is fixed or go there and back in strike of NE,but the migration path and rate in each belt are different.It is possibly related to the uniformity of the faults activity and the active pattern of tectonic stress.
