Video: Japan repairs 15-meter deep sinkhole in two days
A minute-long timelapse video shows two days of repair work on a sinkhole which developed in a road in Japan's Fukuoka city. The 30-meter-wide and 15-meter deep sinkhole had swallowed a section of the four-lane street. The sinkhole was created due to faulty excavation on an underground train tunnel which caused chunks of earth to collapse.
