Core Event: Major Quake Strikes Central Panama
On Friday, October 9, a powerful earthquake struck central Panama. Preliminary data from the Institute of Geosciences of the University of Panama indicated a magnitude 7.0 event at a depth of 10 km, located about 39 km west of Tonosí. The same institute later reported a magnitude 7.2 quake at a depth of 4 km in the same vicinity. The U.S. Geological Survey (USGS) initially listed the tremor as magnitude 8.0, then revised it to roughly 7.6, and finally to 7.7 with an epicenter about 12 km west-southwest of Pitaloza Arriba in Herrera Province, at a depth of 12.6 km.
Conflicting Reports & Gaps
The differing magnitude and depth figures illustrate the evolving nature of seismic assessment. The Institute of Geosciences provided two separate preliminary estimates (7.0 / 10 km and 7.2 / 4 km), while the USGS’s final estimate settled on magnitude 7.7 / 12.6 km. No source has confirmed a single definitive magnitude, and the precise epicenter location varies between “west of Tonosí” and “west-southwest of Pitaloza Arriba.”
Impact and Immediate Response
Structural damage was reported in several provinces, including the San Juan Bautista Cathedral and municipal offices in Penonomé (Coclé), as well as the Santiago Cathedral in Veraguas. The Iguana Mall in Penonomé suffered roof-panel failures. Approximately 13 aftershocks were recorded within hours, one reaching magnitude 6.0 north of Tonosí. The USGS estimated that about 4.6 million people felt moderate to severe shaking.
Tsunami warnings were issued by the USGS and the Pacific Tsunami Warning Center for Pacific coasts of Panama, Colombia, Costa Rica, Ecuador, Peru, Nicaragua, Guatemala, El Salvador, and Mexico. No hazardous waves had been confirmed at the time of reporting.
Transportation disruptions included a temporary suspension of operations at Tocumen International Airport for safety assessments and a halt to Panama Metro lines 1 and 2. The Ministry of Education suspended afternoon classes nationwide, and the University of Panama closed its campuses and administrative offices as a precaution.
Official Statements & Responses
President José Raúl Mulino announced on social media that he had directed Minister of Government Dinoska Montalvo and security agencies to assess the quake’s effects. The Ministry of Education confirmed the nationwide suspension of classes, while the University of Panama cited safety of its community as the reason for halting academic activities.
Data & Statistics
- Reported magnitudes: 7.0 (Institute of Geosciences), 7.2 (Institute of Geosciences), 7.6 (USGS interim), 7.7 (USGS final).
- Depth estimates: 4 km, 10 km, and 12.6 km.
- Aftershocks: ~13 recorded, including one of magnitude 6.0.
- Population feeling shaking: ~4.6 million (USGS).
- No immediate confirmed deaths, injuries, or major damage reported.
The event remains fluid, with magnitude assessments, tsunami alerts, and damage reports subject to ongoing verification.
