M4.1 Earthquake in the Afghanistan-Tajikistan-Pakistan region — August 4, 2023
2023-08-04 20:58:36 UTC (2023-08-04) · approx. 1:58 AM UTC+5 local
On August 4, 2023 at 20:58 UTC, a magnitude 4.1 intermediate depth earthquake struck in the Afghanistan-Tajikistan-Pakistan region, at a depth of 243.3 km and coordinates 36.7125°, 71.0798°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
