MEXICO CITY - A powerful earthquake is shaking Mexico's capital city, causing people to flee swaying buildings and knocking out lights to part of the city.
The U.S. Geological Survey said the earthquake had a magnitude of 8.2 and its epicenter was 165 kilometers (102 miles) west of Tapachula in southern Chiapas state. It had a depth of 35 kilometers.
The death toll in the massive earthquake in Mexico has risen to at least five people, including two children in Tabasco state.
Tabasco Gov. Arturo Nunez said that one of the children died when a wall collapsed, and the other was a baby who died in a children's hospital that lost electricity, cutting off the supply to the infant's ventilator.
The other three deaths were in Chiapas state, in San Cristobal de las Casas.
The U.S. Tsunami Warning System said the earthquake was a potential tsunami threat to several Central American countries, including the Pacific coastlines of Guatemala, Honduras, Mexico, El Salvador and Costa Rica. It said the threat was still being evaluated for Hawaii, Guam and other Pacific islands.
Even in distant Mexico City the quake was felt so strongly that frightened residents gathered in the streets in the dark, fearing buildings would collapse.
