On January 26, 2026 at 06:56 UTC, a magnitude 5.5 shallow crustal earthquake struck 9 km SE of Dianga, China, at a depth of 10.0 km and coordinates 34.0108°, 103.2909°. The earthquake was reported felt by 2 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.8 (very strong). The USGS PAGER system issued a yellow alert level for this event, indicating local impact possible. This earthquake was detected by 215 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 651, making it a moderate-impact event. The nearest populated place is Dianga (population 0).

Physical scale: An earthquake of magnitude 5.5 releases seismic energy equivalent to roughly 3 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.8 km — a useful intuition for the size of the slip patch on the fault.
