An enormous hole in the ground in China is causing increasing concern to local residents - not least because it keeps getting bigger.
The cave-in first appeared in September 2012, when parts of a field suddenly began sinking for six days.
Now residents of the village in Guangyuan in Sichuan province fear the pit will continue to grow until it starts swallowing nearby houses.
The hole currently measures 24.9 metres in diameter.
Local officials fear it will get even larger during the forthcoming rainy season.
It is reported that authorities have given up trying to think of a way to repair the cave-in and are instead advising residents to abandon their homes and move away.
Geological conditions in the area mean the ground is prone to sudden collapse, thanks to weak rock formations and vast systems of underground drains.
