M5.3 Earthquake in the Komandorskiye Ostrova, Russia region — January 30, 2021
2021-01-30 08:35:16 UTC (2021-01-30) · approx. 7:35 PM UTC+11 local
On January 30, 2021 at 08:35 UTC, a magnitude 5.3 shallow crustal earthquake struck in the Komandorskiye Ostrova, Russia region, at a depth of 19.2 km and coordinates 54.1649°, 169.2391°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
