2025-09-17 14:46:40 UTC (2025-09-17) · approx. 1:46 AM UTC+11 local
On September 17, 2025 at 14:46 UTC, a magnitude 5.0 shallow crustal earthquake struck 206 km E of Petropavlovsk-Kamchatsky, Russia, at a depth of 10.0 km and coordinates 53.0445°, 161.7109°. This earthquake was detected by 142 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.
The epicenter is located in Russia, a region characterized by the Kuril-Kamchatka subduction zone on the northwestern Pacific Ring of Fire. The nearest mapped fault system is the Kuril-Kamchatka Trench. View all earthquakes in Russia.
