2024-10-28 22:26:04 UTC (2024-10-28) · approx. 9:26 AM UTC+11 local
On October 28, 2024 at 22:26 UTC, a magnitude 4.5 shallow crustal earthquake struck 140 km SE of Gizo, Solomon Islands, at a depth of 10.0 km and coordinates -8.8379°, 157.8872°. This earthquake was detected by 18 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
