2024-08-04 17:00:20 UTC (2024-08-04) · approx. 3:00 AM UTC+10 local
On August 4, 2024 at 17:00 UTC, a magnitude 4.5 shallow crustal earthquake struck 166 km ESE of Kuril’sk, Russia, at a depth of 42.1 km and coordinates 44.6175°, 149.8049°. This earthquake was detected by 46 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 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.
