On October 8, 2024 at 00:35 UTC, a magnitude 5.7 shallow crustal earthquake struck southeast of Easter Island, at a depth of 10.0 km and coordinates -36.2933°, -99.1831°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 161 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 500, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.7 releases seismic energy equivalent to roughly 5 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 5.2 km — a useful intuition for the size of the slip patch on the fault.
