Abstract

Abstract

On January 7^th, 2025, an M_s 6.8 earthquake occurred in Dingri County, Xizang Autonomous Region, triggering coseismic geological hazards and causing deformation of some existing geological hazards. In order to deeply analyze their development trend and potential risks, based on primary data obtained from on-site emergency investigation and comprehensive studies of regional geological data, this paper studies the development and distribution characteristics as well as disaster prevention and reduction countermeasures of the geological disasters in the earthquake area. The results show that 868 geological disaster sites, including landslides, debris flows, collapses and ground cracks, were identified before the earthquake, and this number increased by 91 after the earthquake. The scales of the disasters were mainly small and medium; 107 geological disaster sites were significantly or slightly changed due to the earthquake. It is believed that, although the earthquake did not cause a large number of coseismic geological hazards, it will still have a certain impact on the stability of high mountains, glaciers, glacial lakes, etc. It is necessary to further carry out detailed investigation and evaluation in the earthquake area, and to pay attention to the research and evaluation of the genetic mechanism of sand liquefaction in the valley area, as well as to investigate the potential risks that may be posed to regional towns and engineering constructions. The research results of this paper can provide a scientific reference for the determination of key areas and objects of geological disaster investigation and post-disaster reconstruction planning in the Dingri County earthquake area.
