On September 17, 2023 at 11:53 UTC, a magnitude 4.9 intermediate depth earthquake struck 64 km WNW of Kirakira, Solomon Islands, at a depth of 88.6 km and coordinates -10.1917°, 161.3950°. This earthquake was detected by 92 seismic stations with good location accuracy and was assigned a USGS significance rating of 370, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
