2024-07-21 09:26:25 UTC (2024-07-21) · approx. 7:26 PM UTC+10 local
On July 21, 2024 at 09:26 UTC, a magnitude 4.6 shallow crustal earthquake struck 200 km NE of Kuril’sk, Russia, at a depth of 10.0 km and coordinates 46.4027°, 149.8387°. This earthquake was detected by 78 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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.
