M4.6 Earthquake north of the New Siberian Islands — September 29, 2024
2024-09-29 05:18:45 UTC (2024-09-29) · approx. 2:18 PM UTC+9 local
On September 29, 2024 at 05:18 UTC, a magnitude 4.6 shallow crustal earthquake struck north of the New Siberian Islands, at a depth of 10.0 km and coordinates 79.9937°, 137.0957°. This earthquake was detected by 74 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
