On January 12, 2024 at 23:30 UTC, a magnitude 4.6 intermediate depth earthquake struck 142 km SE of Lata, Solomon Islands, at a depth of 97.4 km and coordinates -11.7672°, 166.5714°. This earthquake was detected by 30 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
