M4.4 Earthquake in the Easter Island region — July 19, 2022
2022-07-19 23:17:44 UTC (2022-07-19) · approx. 3:17 PM UTC-8 local
On July 19, 2022 at 23:17 UTC, a magnitude 4.4 shallow crustal earthquake struck in the Easter Island region, at a depth of 10.0 km and coordinates -22.4863°, -113.8956°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
