2025-11-21 07:12:38 UTC (2025-11-21) · approx. 11:12 AM UTC+4 local
On November 21, 2025 at 07:12 UTC, a magnitude 4.7 shallow crustal earthquake struck near Carlsberg Ridge, at a depth of 10.0 km and coordinates 10.6718°, 57.2026°. This earthquake was detected by 45 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
