M5.1 Earthquake east of the Kuril Islands — August 15, 2025
2025-08-15 15:50:17 UTC (2025-08-15) · approx. 1:50 AM UTC+10 local
On August 15, 2025 at 15:50 UTC, a magnitude 5.1 shallow crustal earthquake struck east of the Kuril Islands, at a depth of 10.0 km and coordinates 45.6571°, 153.9083°. This earthquake was detected by 101 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
