Residents in the Bosnian village of Sanica have been left dumbfounded by the appearance of a sinkhole where a pond used to be.
The crater, measuring around 50 metres wide and 30 metres deep, started appearing two weeks ago.
It swallowed up the pond and fish as well as trees next to it. Villagers have dubbed it the “abyss”.
Hazim Hrvatovic, director of the Bosnian geological institute, said it was a geological phenomenon.
“This is absolutely nothing unusual, especially when you know the geological formation here. It is not common, but it happens. In geology this is something that normally happens,” he said.
