Giant Fukuoka sinkhole shows signs of movement after quick repair
First there was a giant sinkhole, suddenly it was gone. Then, a few days after it was filled, it looked like the giant sinkhole could be making a quick return.
The giant Fukuoka sinkhole first appeared on November 8.
Not only did the sinkhole completely block off the street in central Fukuoka, it also crashed banking systems and caused power outages in the area.
Officials had to urgently repair the road, as sewerage spewed into the hole and threatened to seep onto the street. Remarkably, it was repaired in a few days.
Early on Saturday morning, however, only six days after the hole was filled, the road started to sink again.
Fukuoka mayor Soichiro Takashima issued an apology after it was revealed that some sinking was expected. City officials had not told the public that the land would begin to compress, causing slight movement.
"If you have a little bit of anxiety, you'll have to stop and make sure that you're safe," Takashima said.
"I am sorry to have troubled you," he wrote on Facebook.
The road sunk by up to 7cm, The Japan Times reported.
Police closed the road at 1.45am local time on Saturday, and reopened it four hours later, the paper said.
The sinkhole spanned five lanes across and was 15 metres deep.
It took 7000 cubic meters of dirt, sand and debris to fill the hole.
