2023-04-10 07:05:43 UTC (2023-04-10) · approx. 6:05 PM UTC+11 local
On April 10, 2023 at 07:05 UTC, a magnitude 5.3 shallow crustal earthquake struck 122 km W of Lata, Solomon Islands, at a depth of 10.0 km and coordinates -10.7936°, 164.6839°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 117 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity. The nearest populated place is Lata (population 553).
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
