On October 10, 2020 at 13:14 UTC, a magnitude 5.9 shallow crustal earthquake struck in the Easter Island region, at a depth of 10.0 km and coordinates -28.5892°, -112.3535°. 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 5.9 releases seismic energy equivalent to roughly 11 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 7.1 km — a useful intuition for the size of the slip patch on the fault.
