2021-12-19 16:11:47 UTC (2021-12-19) · approx. 3:11 AM UTC+11 local
On December 19, 2021 at 16:11 UTC, a magnitude 4.6 shallow crustal earthquake struck near Solomon Islands, at a depth of 5.0 km and coordinates -11.4901°, 162.7061°.
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.
