2026-10-20 19:53:59 UTC (2 hours ago) · approx. 5:53 AM UTC+10 local
On October 20, 2026 at 19:53 UTC, a magnitude 4.7 shallow crustal earthquake struck near Kuril Islands, at a depth of 28.7 km and coordinates 46.2196°, 152.9149°. This earthquake was detected by 80 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.
