Tokyo: On Sunday ( Feb 2 ), five homes in the immediate vicinity of a massive, ever-widening sinkhole were urged to evacuate, with reportedly no rescue efforts.
A 74-year-old vehicle drivers was sucked into on Tuesday by the hollow, which has since grown 40 meters across, about the length of an Olympic swimming pool.
The growing gap could be the consequence of rusted sewer pipes, according to regional government.
Five homes in the Yashio, in the Saitama place, were asked to take shelter on Sunday, according to a local government official who spoke to AFP.
He added that this is in addition to other residents who live within a 50-meter circle of the chamber and who are also being persuaded to leave.
Chinese rescuers finished constructing a 30 m hill to transport heavy equipment and approach the truck driver on Saturday.
However, a significant number of sewage water was discovered beneath the slope, which, combined with rain, caused the evacuation vision to be halted on Sunday, according to public broadcaster NHK.
With the walls of the opening- around 15m full, according to NHK- eroding, save workers are unable to be inside it for longer.
Initial size of the hole was around 5 m, but it was later increased to a larger opening during the recovery mission on Tuesday night when the larger opening was combined with a larger opening.
To avoid leaking effluent from preventing the operation, around 1.2 million residents living near have been asked to cut back on rain and cleaning.
