南北地震带南北段地震迁移现象
Discussion on earthquake migration phenomenon of northern and southern zone in north-south seismic belt
摘要
Abstract
The migration phenomenon of the earthquakes(M≥5. 0) happened at the southern zone and the earthquakes (M≥4. 5) happened at the northern in north-south seismic belt since 1990 is analyzed. The results show that the moderate-earthquakes have echo phenomenon of northern and southern zone in north-south seismic. This kind of echo phenomenon also presents certain laws. The earthquakes symmetricly distributed about latitude 30°N as a baseline at the southern and northern zone. In this article, further discussion about earthquake type and seismogenic law is presented. Through the contrastive analysis of the focal mechanism, it is found that the northern and southern earthquake type is not consistent, which maybe related with the different geological structure and the force.关键词
