利用静态、动态应力降比值判断东北地震震后趋势
Using the static and dynamic stress drop ratio to judge the trend of the aftershock in Northeast China
摘要
Abstract
After finishing the statistics analysis of spectrum characteristics for moderately strong earthquakes in Heilongjiang Province,it comes to the value of stress drop. UsingY value,the ratio of the static stress drop and dynamic stress drop,the article discuss the aftershock trend judgment. The ratio of the static stress drop and dynamic stress drop is between 0.3 and 0.6 since 2005 in Heilongjiang Province,which is larger than normal. The earthquake type gives priority with the isolated earthquake.关键词
