2025-04-06 22:44:50 UTC (2025-04-06) · approx. 3:44 AM UTC+5 local
On April 6, 2025 at 22:44 UTC, a magnitude 3.8 shallow crustal earthquake struck 40 km ESE of Rasht, Tajikistan, at a depth of 10.0 km and coordinates 38.8750°, 70.7950°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
