M4.5 Earthquake near southern East Pacific Rise — February 28, 2022
2022-02-28 22:14:17 UTC (2022-02-28) · approx. 2:14 PM UTC-8 local
On February 28, 2022 at 22:14 UTC, a magnitude 4.5 shallow crustal earthquake struck near southern East Pacific Rise, at a depth of 10.0 km and coordinates -17.7947°, -116.1424°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
