On November 23, 2022 at 20:36 UTC, a magnitude 4.9 shallow crustal earthquake struck 20 km SE of Malango, Solomon Islands, at a depth of 24.8 km and coordinates -9.8047°, 159.8642°. This earthquake was detected by 48 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.
