A source told The Sun: “A sinkhole has opened up outside Dianne Buswell‘s house near Brighton.

“All the local residents are absolutely horrified and worry it’ll keep expanding and swallow up their homes.”

Sinkholes are depressions or holes in the ground caused by the collapse of a surface layer.

They occur when water dissolves soluble rocks, such as limestone, gypsum, or chalk, creating underground voids.
