2019年8月22日在黑龙江绥滨发生9次小震活动,地震活动分布的时间与空间相对集中。利用调制地震、震源机制解及视应力等方法,分析此次小震序列活动特征,并结合黑龙江省以往震例,进行震后趋势分析,初步判定,黑龙江绥滨地区后续发生中强地震的可能性较小。
Nine small earthquakes occurred in Suibin, Heilongjiang Province on August 22, 2019. The small earthquakes are relatively concentrated in time and space. The seismic activity of the small earthquake sequence is analyzed using the methods of modulated earthquake analysis, focal mechanism solution, and apparent stress analysis, and the post-earthquake trend analysis is carried out using previous earthquakes in Heilongjiang Province. A preliminary conclusion is that the possibility of the occurrence of a moderate earthquake in Suibin, Heilongjiang Province is low.
