Panama Earthquake Triggers Regional Seismic and Tsunami Alerts

Seismic activity off Panama's Pacific coast prompted regional warnings about potential structural damage and tsunami hazards on October 9, 2026, after a powerful earthquake struck west of Tonosí in Los Santos province. The University of Panama's Geosciences Institute initially reported a magnitude of 7.2, while communities across Panama and parts of Costa Rica felt the shaking.

The earthquake occurred at 12:56 p.m. local time, or 17:56 UTC, according to the institute's preliminary information cited by teleSUR. Its epicenter was located approximately 39 kilometers west of Tonosí, in the Pacific Ocean, with an initially reported focal depth of 10 kilometers.

A subsequent bulletin reproduced in the report listed the event as reviewed, retained its magnitude at 7.2, and gave a depth of 4 kilometers. The bulletin also placed the earthquake 39 kilometers northwest of Tonosí, reflecting differences in the reported location and depth details.

The offshore earthquake's magnitude and reported shallow depth prompted concerns about possible damage to infrastructure and changes in sea level that could threaten Pacific coastal areas. Authorities and monitoring organizations issued warnings as they assessed the potential consequences of the seismic event.

Reports of the shaking extended beyond the immediate epicentral region. Residents in parts of Panama City, including Tocumen, experienced the earthquake, while tremors were also reported in border areas of Costa Rica.

Community monitoring network Sismo Detector recorded hundreds of public reports within a radius exceeding 300 kilometers from the epicenter, according to teleSUR. Reports came from locations including Almirante in Panama and Ciudad Cortés in Costa Rica's southern Pacific region.

Emergency response and civil protection teams began field assessments to check buildings, essential services, and transportation routes for possible damage. The report did not provide a confirmed casualty count or a verified assessment of structural losses.

Authorities remained on alert because of the exposure of coastal and island communities across the Central American isthmus to seismic and maritime hazards. Officials urged residents to remain calm, avoid potentially unsafe structures, and monitor official bulletins for possible preventive evacuations in areas facing earthquake-related or tsunami threats.
