The epicenter of 2022 Honghe MS5.0 earthquake is located near the southern section of Red River fault zone, which consists of two nearly parallel faults: the Bolumu-Maocaoping fault and the Nanhun-Nabing fault. The Nanhun-Nabing fault is an active fault in the late Pleistocene, and significant water system dislocation deformation exists in the earthquake area. The field investigation after earthquake shows that a 1.2 km long surface rupture appeared on the ridge between Nanhun river and Nanchu river, and its distribution characteristics are consistent with the linear topography of Nanhun-Nabing fault. The deformation properties exhibited by the surface rupture in this area are consistent with the motion characteristics of earthquake rupture. Combined with the focal mechanism solution, it is believed that the Nanhun-Nabing fault is the seismogenic structure of Honghe MS5.0 earthquake.
