M4.7 Earthquake southeast of Easter Island — December 25, 2023
2023-12-25 06:50:58 UTC (2023-12-25) · approx. 11:50 PM UTC-7 local
On December 25, 2023 at 06:50 UTC, a magnitude 4.7 shallow crustal earthquake struck southeast of Easter Island, at a depth of 10.0 km and coordinates -36.2680°, -100.0219°. This earthquake was detected by 88 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
