A magnitude 7.7 earthquake struck Panama on Friday, with shaking reportedly felt across the country after a major tremor was recorded near Pitaloza Arriba, according to USGS.
The USGS initially reported a magnitude 8.0 earthquake near Pitaloza Arriba, Panama, but later lowered it to 7.7. The quake struck at a depth of about 33 kilometers (20 miles) around 12:56 p.m. local time Friday.
Panama’s University of Panama Geosciences Institute reported a magnitude of 7.6 for the same earthquake, with a depth of about 4 kilometers (2.5 miles). The institute located the epicenter about 39 kilometers (24 miles) northwest of Tonosí.
