LONDON -- People were evacuated from their homes in St. Albans overnight after a large sinkhole opened up at the end of a driveway.
The hole, which measures 20 metres by 20 metres (65 feet) and is 10 metres (32 feet) deep, has opened up in Fontwell Close, St. Albans, BBC News reported.
There was already a small hole, which was due to be filled in, but it "opened up substantially" in the early hours of the morning. Dozens of homes have been left without water and electricity.
Aerial video shows the extent of it.

Because the sinkhole took out a section of road, many nearby residents couldn't use their cars.
In August, a 40-foot deep hole opened in Manchester on the Mancunian Way -- a busy commuter route in the city.

Sinkholes, which are collapsed or bowl-shaped features, form when there is a void underground, creating a depression in the land where everything around the area drains.
