2022-01-02 07:02:13 UTC (2022-01-02) · approx. 2:02 PM UTC+7 local
Felt by 5 people across nearby locations. Maximum shaking intensity MMI 5.6 (strong).
On January 2, 2022 at 07:02 UTC, a magnitude 5.4 shallow crustal earthquake struck 99 km E of Shangri-La, China, at a depth of 35.7 km and coordinates 27.7998°, 100.7176°. The earthquake was reported felt by 5 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 5.6 (strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Daxing (population 0).
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
