2024-04-19 20:59:39 UTC (2024-04-19) · approx. 6:59 AM UTC+10 local
On April 19, 2024 at 20:59 UTC, a magnitude 4.8 shallow crustal earthquake struck 85 km S of Shikotan, Russia, at a depth of 45.8 km and coordinates 43.0408°, 146.5580°. This earthquake was detected by 105 seismic stations with excellent 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.
