2023-08-19 19:40:44 UTC (2023-08-19) · approx. 12:40 AM UTC+5 local
On August 19, 2023 at 19:40 UTC, a magnitude 4.2 intermediate depth earthquake struck near Tajikistan, at a depth of 90.6 km and coordinates 37.2579°, 72.6948°.
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.
