RIO DE JANEIRO — A strong aftershock struck Chile on Sunday, a day after a destructive 8.8-magnitude earthquake left hundreds of people dead and a long swath of the country in smoky rubble.

The death toll was expected to rise, particularly around Concepción, Chile's second-largest metropolitan area, which is roughly 70 miles from the quake's center. The aftershock was reported around 8:30 local time Sunday morning from the capital of Santiago, where it shook buildings, according to Reuters.

More than 1.5 million people have displaced by the quake, according to local news services that quoted the director of Chile's emergency management office. In Concepción, which appeared to be especially hard hit, the mayor said Sunday morning that 100 people were trapped under the rubble of a building that had collapsed, according to Reuters.

Elsewhere in Concepción, cars lay mangled and upended on streets littered with telephone wires and power cables. A new 14-story apartment building fell, while an older, biochemical lab at the University of Concepción caught fire.
