2020-09-26 22:58:41 UTC (2020-09-26) · approx. 9:58 AM UTC+11 local
On September 26, 2020 at 22:58 UTC, a magnitude 4.5 shallow crustal earthquake struck 227 km SSE of Ust’-Kamchatsk Staryy, Russia, at a depth of 10.0 km and coordinates 54.4138°, 164.1174°.
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.
