A video showing the ground of an Aberdeen park wobbling like a liquid has been posted online.
A dog walker uploaded the video after coming across the unusual phenomenon in the city’s Hazlehead Park.
The cause of the wobbly ground is currently unknown, however experts have speculated on what it could be.
Professor John Howell, a Geoscientist at the University of Aberdeen said: “My guess would be it is water under the turf. If there is water leaking underground the pressure builds up and the turf layer can become detached from the soil below.
“Because the turf is matted together it forms an impervious layer and behaves like a water-bed.
“This phenomena is rare but when it occurs its normally occurs in parks, golf courses or lawns, where the turf is not so well bound to the underlying soil. Interesting thing is that since there hasn’t been much rainfall recently, this would suggest a burst pipe somewhere just below.”
Members of the public have been urged to stay clear of it for their own safety.
