On February 23, 2024 at 01:51 UTC, a magnitude 6.3 shallow crustal earthquake struck near southern East Pacific Rise, at a depth of 10.0 km and coordinates -35.0892°, -110.7745°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 98 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 611, making it a moderate-impact event.

Physical scale: An earthquake of magnitude 6.3 releases seismic energy equivalent to roughly 43 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 13 km — a useful intuition for the size of the slip patch on the fault.
