M4.6 Earthquake near Greenland Sea — May 14, 2023
2023-05-14 17:57:22 UTC (2023-05-14) · approx. 5:57 PM UTC+0 local
On May 14, 2023 at 17:57 UTC, a magnitude 4.6 shallow crustal earthquake struck near Greenland Sea, at a depth of 10.0 km and coordinates 75.3774°, 7.3661°. This earthquake was detected by 96 seismic stations with excellent 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.
