An investigation is underway after a 12m deep hole opened up in a Cornish car park last weekend.
It is believed that the hole close to properties in St Ives was triggered by the collapse of capping over an historic mine shaft.
Cornwall Search and Rescue was called in following the collapse on Saturday evening and initial investigations suggested that the 1m wide hole could reach up to 3m across.
The area affected remains fenced off while the stability of the ground is verified.
Local mine investigator Stuart Dann said that the mine shaft capping had failed and “the bedrock has coned out underneath” the car park to form “a quite exciting hole”.
