M4.5 Earthquake north of Severnaya Zemlya — July 17, 2022
2022-07-17 18:02:13 UTC (2022-07-17) · approx. 12:02 AM UTC+6 local
On July 17, 2022 at 18:02 UTC, a magnitude 4.5 shallow crustal earthquake struck north of Severnaya Zemlya, at a depth of 10.0 km and coordinates 84.9733°, 94.9946°. This earthquake was detected by 36 seismic stations with good 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.
