Characteristics of Tectonic Environment of Tangshan M_S5.1 Earthquake on July 12, 2020

After the M_S5.1 Tangshan Guye Tashanying earthquake occurred on July 12, 2020, Hebei Earthquake Agency organized a team to go to the earthquake site to carry out intensity and damage investigation. This paper makes a comprehensive analysis of the seismotectonic environment, focal mechanism solution of the M_S5.1 earthquake, intensity and damage, seismicity level in the old Tangshan earthquake area, and the creep anomaly before the earthquake. The specific suggestions for short-term and impending prediction of moderate strong earthquakes in Tangshan old earthquake area are given.
