Parts of a main street have collapsed in a city in southern Japan, creating a huge sinkhole and cutting off power, water and gas supplies to parts of the city.

Authorities said no injuries were reported from Tuesday's pre-sunrise collapse in downtown Fukuoka, which created a massive sinkhole in the middle of the business district.

Officials said the cause of the collapse in the city's Hakata district is under investigation, but linked it to ongoing subway construction nearby. A smaller sinkhole occurred in Fukuoka in 2014 at another location of the subway construction.

The massive cave-in, more than half an Olympic-size pool, appeared near the city's busy Hakata station, with muddy underground water flowing into the hole.

The incident prompted the evacuation of some residents in nearby buildings.
