2023-05-11 12:03:17 UTC (2023-05-11) · approx. 11:03 PM UTC+11 local
On May 11, 2023 at 12:03 UTC, a magnitude 5.0 shallow crustal earthquake struck 102 km SSE of Ust’-Kamchatsk Staryy, Russia, at a depth of 22.5 km and coordinates 55.3610°, 163.0409°. This earthquake was detected by 127 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
