2021-05-19 07:16:13 UTC (2021-05-19) · approx. 5:16 PM UTC+10 local
On May 19, 2021 at 07:16 UTC, a magnitude 4.9 shallow crustal earthquake struck East of the Volcano Islands, at a depth of 10.0 km and coordinates 24.0662°, 145.0417°.
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.
