2023-03-19 23:05:04 UTC (2023-03-19) · approx. 10:05 AM UTC+11 local
On March 19, 2023 at 23:05 UTC, a magnitude 4.8 shallow crustal earthquake struck near Magadanskaya Oblast', Russia, at a depth of 10.0 km and coordinates 63.3837°, 158.2096°. This earthquake was detected by 114 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.
