A 6.6 magnitude earthquake struck Panama Friday afternoon, following a 7.7 magnitude earthquake and multiple aftershocks, including one measured at 5.5, the USGS said. The quakes collapsed buildings near the epicenter and prompted evacuations across the country. The initial 7.7 quake struck at 1:56 p.m. ET, about 6 miles deep near Pitaloza Arriba, shaking Panama City and San José, Costa Rica. Tsunami warnings issued for Panama, Ecuador and other countries were later canceled.
