On February 18, 2025 at 20:40 UTC, a magnitude 4.3 shallow crustal earthquake struck 10 km W of Santa Cruz, Costa Rica, at a depth of 32.2 km and coordinates 10.2469°, -85.6806°. This earthquake was detected by 48 seismic stations with moderate location accuracy and was assigned a USGS significance rating of 292, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
