Magnitude 7.7 Earthquake Strikes Southwestern Panama, Prompting Evacuations and Temporary Airport Closure

A magnitude 7.7 earthquake struck southwestern Panama at 12:56 local time, with the epicenter located approximately 14 kilometers southwest of Pitalosa Arriba, a remote village at the southern tip of the country, at a depth of 10 kilometers, according to the U.S. Geological Survey. The USGS initially reported the magnitude as 8.0, revised it to 7.6, and later settled on 7.7, while the Geosciences Institute of the University of Panama estimated it at 7.2.

The tremors were felt in Panama City, roughly 200 kilometers from the epicenter, where buildings shook and residents evacuated into the streets. The shaking was also felt in neighboring Colombia. Authorities temporarily closed Tocumen International Airport for safety inspections and suspended operations on Metro Lines 1 and 2. The Ministry of Education suspended afternoon classes, while the Panama Canal continued to operate normally.

Local outlet La Prensa reported approximately 30 aftershocks in the hour following the main quake, including one of magnitude 6.4; the USGS confirmed aftershocks of magnitudes 5.8 and 5.6. A National Civil Protection official said damage was concentrated in the central provinces of Veraguas, Herrera, and Los Santos, with the Santiago Cathedral and city hall buildings in Veraguas sustaining partial damage. Power disruptions were reported across six provinces, and no damage had been reported in Panama City as of the time of reporting. The USGS issued a tsunami warning for coastal areas of Panama, Colombia, Costa Rica, Ecuador, Peru, Nicaragua, Guatemala, El Salvador, and Mexico, cautioning that tsunamis could occur within three hours of the quake.

Major seismic events near a national gateway airport typically trigger a precautionary closure for runway, taxiway and terminal inspections before normal operations resume, independent of whether the facility itself sustains damage. Tocumen's temporary shutdown alongside the suspension of Panama City's two metro lines reflects that standard sequence, where transport infrastructure is checked before being cleared rather than kept running on the assumption of no damage.

The Panama Canal's continued normal operation during the closures is itself informative: it shows that lock and waterway systems can run through an event that still halts air and rail traffic nearby, reflecting differences in how each system's safety checks are triggered and cleared.

The next signals to watch are whether Tocumen's inspections clear quickly enough to avoid extended flight delays or diversions, whether the tsunami warning for the listed coastal areas is lifted within the three-hour window the USGS cited, and whether the aftershock sequence — already including a magnitude 6.4 event — produces further infrastructure assessments in Veraguas, Herrera and Los Santos.
