2025-08-14 16:22:34 UTC (2025-08-14) · approx. 3:22 AM UTC+11 local
Felt by 1 person across nearby locations. Maximum shaking intensity MMI 5.1 (strong).
On August 14, 2025 at 16:22 UTC, a magnitude 6.3 shallow crustal earthquake struck 115 km SSE of Lata, Solomon Islands, at a depth of 45.0 km and coordinates -11.6933°, 166.2048°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 5.1 (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 102 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 611, making it a moderate-impact event. The nearest populated place is Lata (population 553).
Physical scale: An earthquake of magnitude 6.3 releases seismic energy equivalent to roughly 43 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 13 km — a useful intuition for the size of the slip patch on the fault.
