M4.9 Earthquake near Lomonosov Ridge — September 28, 2024
2024-09-28 15:43:06 UTC (2024-09-28) · approx. 12:43 AM UTC+9 local
On September 28, 2024 at 15:43 UTC, a magnitude 4.9 shallow crustal earthquake struck near Lomonosov Ridge, at a depth of 10.0 km and coordinates 80.1349°, 137.2343°. This earthquake was detected by 186 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
