In its tectonic summary of the earthquake, the USGS stated, “The January 7, 2025, M7.1 earthquake near Xizang, China, took place due to normal faulting at a shallow depth north of the boundary between the Eurasia and Indian plates.”
The USGS also added, “Focal mechanism solutions suggest that the rupture happened on a roughly north-south striking fault, dipping moderately either to the east or to the west.”
