2023-05-22 13:36:12 UTC (2023-05-22) · approx. 12:36 AM UTC+11 local
On May 22, 2023 at 13:36 UTC, a magnitude 5.2 shallow crustal earthquake struck 157 km ENE of Gizo, Solomon Islands, at a depth of 10.0 km and coordinates -7.6524°, 158.1943°. This earthquake was detected by 102 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
