On November 21, 2025 at 19:47 UTC, a magnitude 4.5 shallow crustal earthquake struck 17 km S of Quepos, Costa Rica, at a depth of 45.0 km and coordinates 9.2728°, -84.1423°. This earthquake was detected by 79 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.
