Abstract:Characteristics of water level co-seismic responses and post seismic effects induced by the MW8.1 Nepal earthquake are analyzed, and the adjustment state of stress is calculated using co-seismic water level changes. The results show that the main types of co-seismic response and post seismic effects are oscillation and rise, respectively. The north-south seismic belt is the main area, with more adjustment induced by the MW8.1 Nepal earthquake, related to the co-seismic adjustment of stress. The stresses on the border of Gausu province and Qinghai province, Yunnan, and the borders of Sichuan, Chongqing and Guizhou enhanced obviously. In 2 years after MW8.1 Nepal earthquakes, four earthquakes occurred in the border of Gausu and Qinghai provinces, and in Yunnan. This indicates that the area of the co-seismic enhancement of stress inverted by co-seismic water level might have certain indicative significance to future earthquakes.
