A massive sinkhole in Guangzhou, China, swallowed up buildings and knocked out power to thousands of residents this week, and it was all caught on video.
According to reports, the sinkhole is about 3,230 square feet in diameter and very deep. It caused buildings to implode as if they were being detonated.
Neighboring structures 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.
Sinkholes are, unfortunately, nothing new, and some are human-induced.
In Beijing, massive bomb shelters, "constructed amid fears of an impending nuclear attack during the height of Chinese-Soviet tensions," may be a factor.
Sinkholes have often been correlated to land-use practices, especially from groundwater pumping and from construction and development practices.
They can also occur in areas where the rock beneath the surface can be easily dissolved by groundwater, or due to other natural forces below.
