【Pihit】

A monster sinkhole that was repaired in 48 hours in the Japanese city of Fukuoka is Pihitsinking again.

Local police closed part of the road near JR Hakata railway station because a section of it began sinking again. The road has since been re-opened.

An official of the Fukuoka city government said the road had sunk by up to 7 centimetres over an area of 30 square metres.

City officials said some movement had been expected as a special mix of soil and cement used to fill the original sinkhole may have compressed a layer of soil underneath.

Fukuoka mayor Soichiro Takashima posted an apology on his Facebook page for not warning residents about the possibility the ground could move again.

Engineers and workers in Fukuoka were praised for how quickly they repaired the massive sinkhole, which swallowed parts of the main street in the city.

The road was fixed in 48 hours but it reopened on Tuesday, Nov. 15, after local officials declared the stretch safe.

The sinkhole began just 300 meters from the JR Hakata railway station and grew to more than half the size of an Olympic pool (30m). It resulted in power, water and gas supplies being cut in parts of the city. No one was injured.
