2025-07-18 06:28:08 UTC (2025-07-18) · approx. 10:28 AM UTC+4 local
On July 18, 2025 at 06:28 UTC, a magnitude 5.3 shallow crustal earthquake struck near Carlsberg Ridge, at a depth of 10.0 km and coordinates 8.4441°, 58.5586°. This earthquake was detected by 59 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
