On October 13, 2022 at 17:30 UTC, a magnitude 4.9 shallow crustal earthquake struck 200 km ESE of Kirakira, Solomon Islands, at a depth of 10.0 km and coordinates -11.4075°, 163.4824°. This earthquake was detected by 53 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.

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.
