On September 5, 2022 at 04:52 UTC, a magnitude 6.6 shallow crustal earthquake struck 44 km SE of Kangding, China, at a depth of 12.0 km and coordinates 29.6786°, 102.2360°. The earthquake was reported felt by 56 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 8.0 (violent). The USGS PAGER system issued a orange alert level for this event, indicating regional impact possible. This earthquake was detected by 141 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 1051, making it one of the most significant global earthquakes in recent days. The nearest populated place is Luqiao (population 0).

Physical scale: An earthquake of magnitude 6.6 releases seismic energy equivalent to roughly 120 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 22 km — a useful intuition for the size of the slip patch on the fault.
