On June 15, 2020 at 04:09 UTC, a magnitude 5.2 shallow crustal earthquake struck 160 km SSW of Gizo, Solomon Islands, at a depth of 10.0 km and coordinates -9.3650°, 156.1168°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected.
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.
