2020-10-22 01:57:53 UTC (2020-10-22) · approx. 12:57 PM UTC+11 local
On October 22, 2020 at 01:57 UTC, a magnitude 4.8 shallow crustal earthquake struck 113 km W of Kirakira, Solomon Islands, at a depth of 10.0 km and coordinates -10.4902°, 160.8885°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
