2024-04-06 17:25:40 UTC (2024-04-06) · approx. 11:25 AM UTC-6 local
On April 6, 2024 at 17:25 UTC, a magnitude 4.3 shallow crustal earthquake struck 12 km W of Guápiles, Costa Rica, at a depth of 10.0 km and coordinates 10.2007°, -83.8935°.
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.
