Outline
On January 7, 2025, an earthquake of MS6.8 occurred in Dingri, Xizang, which produced a surface deformation zone about 35 km long. By means of high-resolution image interpretation, field geological survey and aerial photogrammetry of unmanned aerial vehicle, it is found that the northern part of the surface deformation zone of the Dingri earthquake is mainly a normal fault seismic fracture zone with vertical coseismic dislocation of 2 m to 3 m, and secondary rupture development of the nature of the strike-slip is also visible. However, the southern part of the deformation zone presents complex deformation characteristics, including both tensile deformation and extrusion deformation. Among them, the tensile deformation is mainly located on the west side of the linear fault scarp of the SN-trending Dengmocuo fault, and the deformation zone with the same strike as the fault may be a seismic surface fracture zone with structural significance. while the extrusion deformation zone is mainly distributed at the eastern boundary of lake-eroded shoal, located on the west side of the tensile deformation zone, with different directions. It is speculated that under a westward thrusting force, the surface frozen layer, as a rigid slider, slipped along the underlying saturated aquifer, cracked into multiple blocks, slipped westward and collided with each other, forming a multi-directional extrusion deformation zone.
