A powerful 7.4 magnitude earthquake struck western Colombia on Monday, killing at least 111 people, damaging hundreds of buildings and leaving many trapped under debris while their loved ones and rescue workers searched through rubble. Besides Cali, the quake ravaged cities across western Colombia, including Pereira, Quibdo and Manizales, and was felt in neighboring Ecuador and Panama. The epicenter was in San Jose del Palmar, a community of about 4,800 people in the Choco region about 250 miles west of Bogota, the U.S. Geological Survey said. The Pacific, particularly the Choco region, is one of Colombia's poorest, nestled in dense jungle. Pereira Mayor Mauricio Salazar told a local radio station there were at least 15 collapsed buildings where people were feared trapped.
