Thirty metre large Japanese sinkhole disappears in two days

Christchurch construction workers may want to take a leaf out of Japan’s book after a giant sinkhole has been repaired in a week.
The sinkhole which ripped apart a street in the Japanese city Fukuoka on 8 November was 30m wide and 15m deep.
Construction workers moved quickly to have it repaired by 5am Tuesday local time, with the five-lane street reopening in time for rush hour.
Photos of the newly reopened street show no evidence of the sinkhole’s existence.
The city’s mayor Soichiro Takashima has assired the Fukuoka’s residents that the ground is now 30 times stronger than before.
Mr Takashima has released a statement apologising for the "great trouble" for residents and thanking workers for their efforts.
He insisted that an investigation into the incident’s causes would continue. City officials have said it could have been caused by underground construction nearby.
