On November 25, 2021 at 12:04 UTC, a magnitude 6.1 shallow crustal earthquake struck 77 km E of Lata, Solomon Islands, at a depth of 10.0 km and coordinates -10.7451°, 166.5074°. The earthquake was reported felt by 51 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.8 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. The nearest populated place is Lata (population 553).

Physical scale: An earthquake of magnitude 6.1 releases seismic energy equivalent to roughly 21 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 9.7 km — a useful intuition for the size of the slip patch on the fault.
