2022-08-14 08:20:00 UTC (2022-08-14) · approx. 2:20 PM UTC+6 local
Felt by 1 person across nearby locations. Maximum shaking intensity MMI 7.4 (severe).
On August 14, 2022 at 08:20 UTC, a magnitude 5.7 shallow crustal earthquake struck 194 km NNE of Nagqu, China, at a depth of 5.0 km and coordinates 33.1157°, 92.7977°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 7.4 (severe). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 191 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 650, making it a moderate-impact event. The nearest populated place is Segong (population 0).
Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 km — a useful intuition for the size of the slip patch on the fault.
