Three houses had to be evacuated amid fears they could collapse after a huge 25 ft wide sinkhole opened up in a street.
Police cleared the properties on Magdalen's Close in Ripon, North Yorkshire, at 5.40pm after receiving reports the huge sinkhole had appeared.
Officers carried out house-to-house checks in the area to warn people close to the affected properties.
Police, fire crews and the ambulance service remained at the scene with utility services' engineers and structural engineers who were assisting with the incident.
A North Yorkshire police spokesman said: "The affected property and two houses nearby have been evacuated and a cordon has been put in place to protect members of the public. At this stage no injuries have been reported."
North Yorkshire fire and rescue service said that a fire engine and a heavy rescue unit from Ripon were at the scene, where cracks had appeared in the ground, damaging to a building.
A spokeswoman said: "There are no occupiers in the property and a dog has been successfully rescued. Residents from adjacent properties have been evacuated as a precaution.
"The crews have cordoned off the area and are awaiting the arrival of specialist engineers."
The spokeswoman said the sinkhole was about 25 feet wide.
The British Geological Survey has said that the most susceptible area in the UK for sinkholes is the Permian gypsum deposits of north-east England, particularly around Ripon.
It says large sinkholes have developed around Ripon, some of which have affected property and infrastructure. This is because gypsum is far more soluble than limestone, and thus dissolves more rapidly.
