On August 11, 2023 at 21:45 UTC, a magnitude 4.5 intermediate depth earthquake struck 19 km NNW of Güiria, Venezuela, at a depth of 85.9 km and coordinates 10.7463°, -62.3385°. This earthquake was detected by 35 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
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.
