M4.5 Earthquake north of Severnaya Zemlya — October 27, 2022
2022-10-27 20:52:16 UTC (2022-10-27) · approx. 4:52 AM UTC+8 local
On October 27, 2022 at 20:52 UTC, a magnitude 4.5 shallow crustal earthquake struck north of Severnaya Zemlya, at a depth of 10.0 km and coordinates 82.8050°, 116.9637°. This earthquake was detected by 65 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
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.
