On October 8, 2024 at 19:22 UTC, a magnitude 4.6 shallow crustal earthquake struck 98 km SSW of Kirakira, Solomon Islands, at a depth of 10.0 km and coordinates -11.3042°, 161.6581°. This earthquake was detected by 43 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
