M4.6 Earthquake near Carlsberg Ridge — November 23, 2022
2022-11-23 23:25:13 UTC (2022-11-23) · approx. 3:25 AM UTC+4 local
On November 23, 2022 at 23:25 UTC, a magnitude 4.6 shallow crustal earthquake struck near Carlsberg Ridge, at a depth of 10.0 km and coordinates 1.0877°, 67.2781°. This earthquake was detected by 23 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
