A big sinkhole appeared without warning at around 12 am Wednesday on a road in Xiang’an District, Xiamen, but no one was injured, reports Strait News. The sinkhole on Zengwu Road near Meidi Yadeng Neighborhood is at least 2 metres deep and 1 metre in diameter, fortunately, no one was walking on the section when the accident happened, according to Xiang’an officials. Crews have shut down the road and worked through the night to clean the rubble in the hole. An underground pipe, which was crushed by heavy-duty vehicles several years ago and failed to be repaired, was considered to have caused the road to cave-in. Ms Huang, who lives around the site, hoped an overall check for groundsill in the area will be launched to prevent things like this from happening again.
