2024-11-09 20:58:58 UTC (2024-11-09) · approx. 4:58 AM UTC+8 local
On November 9, 2024 at 20:58 UTC, a magnitude 4.2 shallow crustal earthquake struck east of Severnaya Zemlya, at a depth of 10.0 km and coordinates 80.6685°, 121.7897°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
