This geological phenomenon called “sinkhole” (literally sink hole) or “sinkholes” appeared in the center of Ruijin (southeast China) yesterday. The giant hole with an area of 30 square meters was formed in the side of the road, also engulfing a portion of the sidewalk.
It is caused by the dissolution of limestone under the surface by rain and then the bursting of pipes or gas pipes.
The hole suddenly opened when the weight to bear on the surface becomes too heavy. The video below shows the opening of the hole and the sinking car and a tree.
