A huge 20m-wide sinkhole has appeared outside a family home in Leshan, in south-west China's Sichuan Province.
According to 58-year-old Zhang Fengrong, the hole opened up overnight. Fengrong said he and several relatives had tried to measure the depth of the pit using a rope attached to a heavy iron, but after they used up the 40m-long rope the iron still hadn't hit ground. "It used to be land for vegetables, but in a blink the land disappeared along with several fruit trees," added Fengrong's son Zhang Shiyin.
