M4.6 Earthquake East of the Volcano Islands — November 10, 2021
2021-11-10 16:31:52 UTC (2021-11-10) · approx. 2:31 AM UTC+10 local
On November 10, 2021 at 16:31 UTC, a magnitude 4.6 shallow crustal earthquake struck East of the Volcano Islands, at a depth of 10.0 km and coordinates 25.5718°, 145.0492°.
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.
