On September 6, 2026 at 10:32 UTC, a magnitude 5.5 shallow crustal earthquake struck near southern East Pacific Rise, at a depth of 10.0 km and coordinates -24.4815°, -115.7103°. This earthquake was detected by 79 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 465, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.5 releases seismic energy equivalent to roughly 3 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.8 km — a useful intuition for the size of the slip patch on the fault.
