Japan Sinkhole Time Lapse
27 August 2018
A busy stretch of road in the Japanese city of Fukuoka has been reopened just days after the sudden emergence of a giant sinkhole which threatened to topple nearby buildings.
In a typical demonstration of Japanese workmanship and efficiency, workers toiled around the clocks and had practically filled in the section of road in just two days, according to local media.
Reconstructing the road was no easy feat — the massive cave-in spanned more than half an Olympic-size pool near the city's busy Hakata station, with muddy underground water flowing into the hole.
Fukuoka mayor Soichiro Takashima, released a statement apologising for the "great trouble" the sinkhole had caused and expressed his gratitude to workers for their efforts completing the restoration work "promptly with safety first".
"From now on I will do my utmost to investigate the cause and compensate for the damage," the statement said.
The cause of the collapse in the city's Hakata district had been linked to ongoing subway construction nearby.
About a week after the repair was concluded, workers monitoring the area noticed the road sank by about 7cm (2.7in) the following Saturday over a 30-sq-m (322 sq-ft) area and was temporarily closed.
Construction officials said the latest subsidence was "within expectations" and it happened because "special soil" used to repair the sinkhole may have compressed soil underneath it as it hardened. The road closed for a few hours that same day, on Saturday.
No one was hurt in either incident.
