Felt by 1 person across nearby locations.
On March 24, 2021 at 13:27 UTC, a magnitude 4.5 shallow crustal earthquake struck near southeast central Pacific Ocean, at a depth of 10.0 km and coordinates -17.8252°, -77.0409°.
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.
