Look out, below. A massive sinkhole in Guangzhou, China, swallowed up buildings and knocked out power to thousands of residents.

According to Shanghaiist, the sinkhole is about 3,230 square feet and plenty deep. A video shows a crowd milling about the sinkhole before it expanded, causing a building to crumble as if it were detonated.

Neighboring buildings were evacuated and streets were blocked by police. “Gas could be smelt from over 30 metres away, and deafening noises could be heard as the land continued to crack and sink,” the Shanghaiist reports.
