2025-08-12 23:06:21 UTC (2025-08-12) · approx. 3:06 AM UTC+4 local
On August 12, 2025 at 23:06 UTC, a magnitude 4.2 shallow crustal earthquake struck near Carlsberg Ridge, at a depth of 10.0 km and coordinates 2.9435°, 65.1877°.
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.
