A 7.7 magnitude Costa Rica earthquake struck southern Panama on Friday, with the epicenter 12 km west-southwest of Pitaloza Arriba on the Pacific side of Panama. The U.S. Tsunami Warning System then issued potential tsunami threats for coasts across the region, turning one country’s quake into a wider Pacific concern.
Panama quake and regional alert
The earthquake occurred shortly before 1 p.m. local time and was followed by over a dozen aftershocks. Hazardous tsunami waves were possible in the next few hours along some coasts in Costa Rica, El Salvador, Peru, Mexico, Guatemala, Panama, Nicaragua, Colombia and Ecuador.
That sequence matters for people near the shore because the earthquake itself was in Panama, but the most immediate concern extended to possible tsunami waves along coasts in several other countries. For residents and workers near ports, beaches and low-lying coastal roads, the practical issue is not the shaking alone but whether the warning window holds long enough for water to reach exposed areas.
Costa Rica and other coasts
Costa Rica was one of the places named in the warning area, alongside El Salvador, Peru, Mexico, Guatemala, Panama, Nicaragua, Colombia and Ecuador. All administrative offices and schools suspended operations after the earthquake, a sign that authorities treated the event as an active regional threat rather than a local tremor.
The aftershocks added pressure to that response. Over a dozen new quakes followed the main shock, which can complicate decisions for coastal communities trying to judge whether they can safely return indoors, move uphill, or wait for further guidance from the warning system.
Pitaloza Arriba and the warning window
Pitaloza Arriba gives the quake a precise location, but the warning area stretched far beyond that point. The source describes the story as developing, and the next practical question is whether hazardous tsunami waves materialize during the next few hours or the regional threat passes without coastal impact.
For now, the clearest action is simple: people in the named coastal zones should stay away from exposed shorelines until the warning window closes. The earthquake has already happened; what remains is whether the sea responds in a way that changes the day for Costa Rica and the other Pacific coasts named in the alert.
