On September 2, 2023 at 06:56 UTC, a magnitude 4.9 shallow crustal earthquake struck 66 km SE of Honiara, Solomon Islands, at a depth of 10.0 km and coordinates -9.8570°, 160.3817°. This earthquake was detected by 49 seismic stations with good 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.
