2026-02-07 01:21:55 UTC (2026-02-07) · approx. 4:21 AM UTC+3 local
On February 7, 2026 at 01:21 UTC, a magnitude 4.9 shallow crustal earthquake struck in the Prince Edward Islands region, at a depth of 10.0 km and coordinates -42.8924°, 42.2726°. This earthquake was detected by 21 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
