On May 26, 2023 at 13:42 UTC, a magnitude 4.9 intermediate depth earthquake struck in the Oruro-Potosi border region, Bolivia, at a depth of 256.6 km and coordinates -18.7307°, -66.9167°. This earthquake was detected by 60 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
