2026-09-01 04:50:45 UTC (10 hours ago) · approx. 11:50 PM UTC-5 local
On September 1, 2026 at 04:50 UTC, a magnitude 3.6 shallow crustal earthquake struck 4 km WSW of Caldera, Panama, at a depth of 10.0 km and coordinates 8.6353°, -82.4204°.
Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
