2023-03-15 02:32:21 UTC (2023-03-15) · approx. 7:32 AM UTC+5 local
On March 15, 2023 at 02:32 UTC, a magnitude 4.7 shallow crustal earthquake struck 172 km SSW of Aqqan, China, at a depth of 17.0 km and coordinates 34.9914°, 81.3504°. This earthquake was detected by 58 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
