On April 6, 2025 at 10:36 UTC, a magnitude 5.0 shallow crustal earthquake struck north of Severnaya Zemlya, at a depth of 10.0 km and coordinates 83.5411°, 113.5862°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 172 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.
