Mexico City ? A strong earthquake swayed tall buildings from Acapulco to Mexico City early Friday, jolting people awake and sending many fleeing to spend the rest of the night outside.

The country escaped the magnitude-6 quake with no deaths or widespread destruction, but several apartment buildings in Mexico City were evacuated and inspected for possible structural damage.

The quake knocked out power to 20 percent of the capital’s center, provoking scattered water and gas leaks and sending fissures through building facades, said national Civil Protection Director Laura Gurza.
