UPDATED Feb. 6, 2016, at 7:40 a.m. ET with new information about victims.
At least 13 people were killed and hundreds injured after a 6.4-magnitude earthquake struck southern Taiwan early Saturday morning, toppling buildings, knocking out power and plunging thousands into darkness. More than 100 people were unaccounted for, local media reported.
The victims include a 10-day-old baby and 40-year-old man, who were pulled from the 17-story Wei Guan Golden Dragon apartment building, the Associated Press reported. More than 240 people were rescued from the rubble of two collapsed high rises.

In live broadcasts on local TV, rescuers could be seen shining spotlights into the windows of one of the collapsed buildings in the city of Tainan, and scaling the highest floors of another. One person was seen scrambling out of the wreckage as a firefighter looked on.

China's state newspaper People's Daily tweeted that "many people are said trapped in debris shouting for help."

Video posted to YouTube showed similar scenes -- firefighters being raised into open windows as spotlights illuminated the damage.
Facebook's Safety Check feature has since been activated for Kaohsiung City, Taiwan.
The China Post, a local newspaper, said at least four separate aftershocks were registered in the area, and the local government had set up an emergency response center. "Onlookers are urged not to block access to emergency crews moving into the area," it said.
Photos shared on Twitter showed big buildings with floors crumpled into one another, or leaning precariously into the street.
The earthquake disrupted 69 power lines, which knocked out the power to more than 121,000 households, said Taiwan Power. 400,000 households also had their water supplies cut off.

Survivors of the earthquake, in social media posts spotted by Reportedly, described an "extremely terrible experience" that was "fucking scary," with tremors that shook one resident of the region "like a bush in the wind."
"The whole building was going crazy," one man wrote.
