On April 30, 2021 at 05:18 UTC, a magnitude 4.9 shallow crustal earthquake struck 142 km SSE of Lata, Solomon Islands, at a depth of 66.9 km and coordinates -11.8973°, 166.3287°.
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.
