| Abstract: | 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. |
