A powerful earthquake struck off the Pacific coast of Panama on Friday, October 9. It prompted widespread emergency responses and warnings of potential tsunami waves across parts of Latin America. The major tremor disrupted daily activities at midday, forcing mass evacuations of office buildings, schools, and commercial centers across multiple provinces.
According to the University of Panama’s Institute of Geosciences (IGC), the primary earthquake struck at 12:56 p.m. local time. The epicenter was located approximately 39 kilometers northwest of Tonosí, situated in the province of Los Santos, at a shallow depth of just 4 kilometers. The institute formally reviewed and confirmed the seismic event at a magnitude of 7.2.
International monitoring networks also recorded the powerful tremor. The U.S. Geological Survey (USGS) documented the seismic event, estimating its magnitude at 7.6 with a focal depth of 33 kilometers. Due to the high magnitude and shallow depth, intense shaking was felt widely throughout the country. It reached the Tocumen metropolitan area and extended across borders into southern Costa Rica.
Aftershocks and Regional Tsunami Monitoring
Following the primary tremor, monitoring agencies tracked continuous seismic activity in the region. A notable aftershock was registered at 1:22 p.m. local time. Preliminary measurements placed this secondary tremor at a magnitude of 6.0, originating at a depth of 10 kilometers.
Because the seismic focus occurred close to Pacific coastal waters, risk management authorities immediately evaluated potential structural damages and sea-level fluctuations. The System National Civil Protection (Sinaproc) and local rescue teams deployed inspection commissions to verify the stability of essential infrastructure, communication routes, and public utilities in settlements near the epicenter.
Impact on Population Centers and Public Safety
Citizens across a radius exceeding 300 kilometers reported feeling the ground motion. In Panama City, residents and office workers fled high-rise buildings. They gathered in open plazas and streets as a safety precaution. Community monitoring groups noted structural concerns in isolated areas, though a comprehensive damage assessment remains ongoing.
| Parameter | Institute of Geosciences (IGC) | U.S. Geological Survey (USGS) |
|---|---|---|
| Magnitude | 7.2 (Reviewed) | 7.6 |
| Epicenter Location | 39 km NW of Tonosí, Los Santos | Offshore Pacific Coast of Panama |
| Focal Depth | 4 kilometers | 33 kilometers |
| Time of Event | 12:56 p.m. Local Time | 12:56 p.m. Local Time |
The Panamanian Executive and emergency management agencies have urged residents to remain calm. They advised people to avoid compromised and unverified structures and to monitor official updates closely as aftershocks continue to pose secondary risks to coastal and vulnerable communities.
