On November 22, 2023 at 17:45 UTC, a magnitude 4.7 shallow crustal earthquake struck 108 km E of Macas, Ecuador, at a depth of 12.8 km and coordinates -2.2421°, -77.1393°. This earthquake was detected by 86 seismic stations with excellent 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.
