M4.5 Earthquake in the Owen Fracture Zone region — February 14, 2021
2021-02-14 23:14:38 UTC (2021-02-14) · approx. 3:14 AM UTC+4 local
On February 14, 2021 at 23:14 UTC, a magnitude 4.5 shallow crustal earthquake struck in the Owen Fracture Zone region, at a depth of 10.0 km and coordinates 13.1158°, 57.5934°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
