On May 16, 2026 at 15:17 UTC, a magnitude 5.7 shallow crustal earthquake struck 33 km NE of Auki, Solomon Islands, at a depth of 23.4 km and coordinates -8.5526°, 160.9161°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.7 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 175 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 500, placing it among routine seismic activity. The nearest populated place is Auki (population 7,882).

Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 km — a useful intuition for the size of the slip patch on the fault.
