2024-10-31 20:51:59 UTC (2024-10-31) · approx. 6:51 AM UTC+10 local
On October 31, 2024 at 20:51 UTC, a magnitude 4.9 shallow crustal earthquake struck 170 km SSE of Kuril’sk, Russia, at a depth of 10.0 km and coordinates 43.9367°, 149.0369°. This earthquake was detected by 87 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
