On July 14, 2023 at 20:47 UTC, a magnitude 4.3 shallow crustal earthquake struck near northern East Pacific Rise, at a depth of 10.0 km and coordinates 10.2511°, -103.8838°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
