Emergency services are on the scene of what is believed to be a gas explosion in Gorleston.
A house in Fredrick Road has been damaged and two people have been taken to hospital with burns.
Norfolk Fire and Rescue Service has asked people to avoid the area following the suspected gas explosion, which happened just after 11.35am today.
A man in his 50s and a woman in her 40s both suffered minor burns and have been taken to the James Paget University Hospital for treatment.
The explosion has blown out an entire wall of a detached property, leaving the ground and first floors exposed.
One half of the road has been cordoned off and firefighters, National Grid staff, police officers and other emergency vehicles remain on the scene.
Bricks, rubble and piping have been strewn across a parking area beside the house, spilling onto the pavement. A BMW car parked next to the house remains in place, damaged where bricks and dust rained down on it.
Fredrick Road is a narrow residential street of red brick houses between Church Road and the A143 Beccles Road.
Two fire crews from Great Yarmouth and a crew from Gorleston, as well as the Urban Search and Rescue Team from Dereham, were called to the normally quiet area just after 11.35am.
A spokesman for Norfolk police said local residents on the road were being advised to stay in their houses while the scene was made safe.
The East of England Ambulance Service said it was called at 11.35am, sending two ambulance crews, an ambulance officer and the Hazardous Area Response Team to help.
There are not believed to be any other casualties.
The gas board and UK Power Networks have isolated the gas and electrical supply to the property, and fire crews are working to making the building and surrounding area safe.
