On April 19, 2022 at 00:20 UTC, a magnitude 5.3 shallow crustal earthquake struck near Santa Cruz Islands, at a depth of 47.5 km and coordinates -10.9376°, 166.0064°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
