M5.4 Earthquake near Kuril Islands — April 4, 2022
2022-04-04 14:13:34 UTC (2022-04-04) · approx. 12:13 AM UTC+10 local
On April 4, 2022 at 14:13 UTC, a magnitude 5.4 shallow crustal earthquake struck near Kuril Islands, at a depth of 27.6 km and coordinates 47.6461°, 154.1382°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected.
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
