M5.8 Earthquake 136 km NNW of Tumxuk, China — December 4, 2025
2025-12-04 07:44:06 UTC (2025-12-04) · approx. 12:44 PM UTC+5 local
Felt by 13 people across nearby locations. Maximum shaking intensity MMI 7.4 (severe).
On December 4, 2025 at 07:44 UTC, a magnitude 5.8 shallow crustal earthquake struck 136 km NNW of Tumxuk, China, at a depth of 9.0 km and coordinates 41.0099°, 78.4441°. The earthquake was reported felt by 13 peopleacross 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 260 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 654, making it a moderate-impact event. The nearest populated place is Akqi (population 0).
Physical scale: An earthquake of magnitude 5.8 releases seismic energy equivalent to roughly 8 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 6.1 km — a useful intuition for the size of the slip patch on the fault.
