M5.9 Earthquake northwest of the Kuril Islands — April 13, 2025
2025-04-13 09:13:32 UTC (2025-04-13) · approx. 7:13 PM UTC+10 local
On April 13, 2025 at 09:13 UTC, a magnitude 5.9 deep-focus earthquake struck northwest of the Kuril Islands, at a depth of 369.0 km and coordinates 48.7331°, 149.7932°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 197 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 536, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.9 releases seismic energy equivalent to roughly 11 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 7.1 km — a useful intuition for the size of the slip patch on the fault.
