On December 2, 2022 at 15:44 UTC, a magnitude 4.6 shallow crustal earthquake struck 23 km SSE of Muisne, Ecuador, at a depth of 47.2 km and coordinates 0.4178°, -79.9285°. This earthquake was detected by 39 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
