A powerful 7. 6 magnitude earthquake struck off Panama's southern coast Friday, shaking the country's capital as officials investigated a potential tsunami threat.
The U. S. Geological Survey initially measured the earthquake at magnitude 8. 0 before lowering its estimate to 7. 6. The quake struck at 1: 56 p. m. ET, approximately 6 miles beneath the surface, near Pitaloza Arriba, Panama.
