2025-04-30 18:19:15 UTC (2025-04-30) · approx. 10:19 PM UTC+4 local
On April 30, 2025 at 18:19 UTC, a magnitude 4.3 shallow crustal earthquake struck near Carlsberg Ridge, at a depth of 10.0 km and coordinates 10.5107°, 56.9341°.
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.
