2020-12-20 18:45:08 UTC (2020-12-20) · approx. 10:45 PM UTC+4 local
On December 20, 2020 at 18:45 UTC, a magnitude 4.3 shallow crustal earthquake struck 47 km N of Torbat-e J?m, Iran, at a depth of 10.0 km and coordinates 35.6717°, 60.6578°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
