M4.7 Earthquake near Carlsberg Ridge — May 18, 2023
2023-05-18 00:18:59 UTC (2023-05-18) · approx. 4:18 AM UTC+4 local
On May 18, 2023 at 00:18 UTC, a magnitude 4.7 shallow crustal earthquake struck near Carlsberg Ridge, at a depth of 10.0 km and coordinates 9.5438°, 57.8414°. This earthquake was detected by 101 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.
