M5.1 Earthquake 155 km E of Shikotan, Russia — February 28, 2022
2022-02-28 22:04:30 UTC (2022-02-28) · approx. 8:04 AM UTC+10 local
On February 28, 2022 at 22:04 UTC, a magnitude 5.1 shallow crustal earthquake struck 155 km E of Shikotan, Russia, at a depth of 10.0 km and coordinates 43.9146°, 148.6452°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
