On April 3, 2023 at 21:46 UTC, a magnitude 5.1 intermediate depth earthquake struck 70 km SW of Atocha, Bolivia, at a depth of 217.6 km and coordinates -21.3813°, -66.7051°. This earthquake was detected by 204 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
