Residents of two homes were forced to flee after their gardens fell into a disused mine.
The pair of bungalows were left uninhabitable when a massive 2m (6.4ft) hole opened up in the gardens.
The homes are in Redruth in Cornwall - an area where there are many disused mines mainly from the tin and copper mining industry.
Properties on the street were said to have lost electricity following the mine collapse on Sunday.
A spokesperson for Cornwall Council told the BBC residents "made their own arrangements to leave their homes" and were advised to contact insurers and engineers.
