M4.2 Earthquake in the Afghanistan-Tajikistan-Pakistan region — March 23, 2021
2021-03-23 19:36:10 UTC (2021-03-23) · approx. 12:36 AM UTC+5 local
On March 23, 2021 at 19:36 UTC, a magnitude 4.2 intermediate depth earthquake struck in the Afghanistan-Tajikistan-Pakistan region, at a depth of 168.1 km and coordinates 36.7210°, 71.5277°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
