| Abstract: | Introduces the basic parameters,focal mechanism solutions,precise positioning and other data of the two earthquakes of Xinjiang Jiashi M S5.4 earthquake on January 18th,2020 and M S6.4 earthquake on January 19th,2020,and we analyzes the types and attenuation of Jiashi M S6.4 earthquake sequence features and various digital seismological data of the aftershock sequence,and compare the sequence with the historical earthquake sequence,and put forward the post-earthquake trend judgment opinions.According to the analysis,the sequence is pre-main-co-type,and the aftershock sequence decays rapidly. |
