US Geological Survey lowers initial estimate to magnitude 7.6
Times now ↗Colombian geological service reports shallow quake felt across cities
Infobae ↗Earthquake shaking is felt in Panama City
Notícias ao Minuto ↗Initial report places offshore Panama earthquake at magnitude eight
Times of India ↗How it started
A powerful earthquake struck off Panama's southern coast on Friday, October 9, prompting a tsunami warning. Times of India initially reported the quake as magnitude 8.
The shaking reached Panama City, according to Notícias ao Minuto. The immediate concern extended beyond the earthquake itself to the possibility of tsunami waves along Pacific coasts.
How it unfolded
On October 9, Infobae reported a magnitude 7.9 earthquake shortly after 12:56 p.m. Citing the Colombian Geological Service, it described the quake as shallow and said it was felt in several Colombian cities.
Times now reported that the US Geological Survey lowered its initial magnitude estimate from 8.0 to 7.6. It placed the earthquake near Pitaloza Arriba in southern Panama. That account describes a revised estimate, not a separate second earthquake.
Other October 9 reports gave different figures. India Today reported magnitude 7.6 and possible tsunami waves along the Pacific coast, while ABCNews.com reported magnitude 7.7. A report published at 18:24 GMT by RT en Español - Noticias put the magnitude at 7.2.
The threat notices covered a much wider area than Panama. According to ABCNews.com, the US Tsunami Warning System identified potential tsunami threats for Costa Rica, El Salvador, Peru, Mexico, Guatemala, Panama, Nicaragua, Colombia and Ecuador.
Where it stands
The available reports agree that a strong earthquake struck Panama and prompted tsunami alerts, but they do not agree on its magnitude. The clearest explanation for at least part of that difference is the downward revision reported by Times now.
The coverage describes potential tsunami threats, not confirmed wave arrivals. It does not provide verified casualty figures, a damage assessment or confirmation that the alerts have been lifted.
What to watch
The key pending information is whether tsunami waves are recorded along the coasts covered by the threat notices, and whether those notices are maintained, revised or withdrawn. The nine-country list reported by ABCNews.com establishes the scope of the potential threat, not confirmed impacts in each country.
Further seismic updates could also clarify the magnitude. Reports on damage and casualties remain another major gap in the available coverage.
