On February 4, 2026 at 11:08 UTC, a magnitude 4.9 shallow crustal earthquake struck in the Galapagos Islands, Ecuador region, at a depth of 9.8 km and coordinates 2.5718°, -95.1898°. This earthquake was detected by 120 seismic stations with good 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.
