2025-03-06 15:31:56 UTC (2025-03-06) · approx. 1:31 AM UTC+10 local
On March 6, 2025 at 15:31 UTC, a magnitude 4.7 intermediate depth earthquake struck northwest of the Kuril Islands, at a depth of 292.7 km and coordinates 48.2685°, 150.6034°. This earthquake was detected by 91 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
