On May 27, 2022 at 18:22 UTC, a magnitude 5.4 shallow crustal earthquake struck near northern East Pacific Rise, at a depth of 10.0 km and coordinates 8.4234°, -102.9821°.0 The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 145 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 449, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.
