2020-09-11 16:47:14 UTC (2020-09-11) · approx. 8:47 PM UTC+4 local
On September 11, 2020 at 16:47 UTC, a magnitude 4.3 shallow crustal earthquake struck near Carlsberg Ridge, at a depth of 10.0 km and coordinates 6.6331°, 60.2551°.
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.
