Abstract

Abstract: Field survey showed and steitistics that the macroscopic epicenter of November 30, 2021 M_S5.8 Shuanghu earthquake is located near Shenyazadi Village. The maximum intensity of the Shuanghu earthquake could reach Ⅶ degree. Its macroscopic epicenter location, maximum intensity range, major aftershock distribution, etc. are controlled by the fault activity. The surface rupture and seismic mechanism are consistent, which consistently indicates that Wuru cuo fault is the seismic structure.This earthquake produced some clear surface ruptures, which is of great significance for further study of the relationship between magnitude and rupture length.

Key words: Qinghai-Tibet Plateau, Wuru cuo, Earthquake intensity, Seismic structure
