M5.0 Earthquake near Kuril Islands — October 20, 2025
2025-10-20 22:30:30 UTC (2025-10-20) · approx. 8:30 AM UTC+10 local
On October 20, 2025 at 22:30 UTC, a magnitude 5.0 shallow crustal earthquake struck near Kuril Islands, at a depth of 10.0 km and coordinates 46.2204°, 153.1124°. This earthquake was detected by 62 seismic stations with good location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
