There are several types of sinkholes, also known as dolines, caused by different processes, according to the British Geological Survey.
Sinkholes mainly occur in what is known as ‘karst terrain’; areas of land where soluble bedrock (such as limestone or gypsum) can be dissolved by water.
Collapse sinkholes are common in parts of South Wales where sandstone rocks overlie cavernous limestone, according to the British Geological Survey.
SES Water said one of its water main pipes had burst in Godstone High Street.
Surrey Police said on Tuesday that Godstone High Street was closed between Oxted Road and Bletchingley Road following reports of a sinkhole on Monday night.
