2024-04-09 09:56:43 UTC (2024-04-09) · approx. 7:56 PM UTC+10 local
On April 9, 2024 at 09:56 UTC, a magnitude 4.8 shallow crustal earthquake struck 133 km SE of Kuril’sk, Russia, at a depth of 55.4 km and coordinates 44.3489°, 149.0268°. This earthquake was detected by 84 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
