On July 9, 2025 at 18:39 UTC, a magnitude 4.9 shallow crustal earthquake struck 77 km W of Turpan, China, at a depth of 10.0 km and coordinates 43.0295°, 88.2292°. This earthquake was detected by 111 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
