February 27, after six days and nights of heavy thunder in the county of Guangyuan, Sichuan, formed massive failure lots. Formed pit has dimensions of 20 meters in diameter.
According to residents of adjacent villages, failure began to form in September . All six days the process was accompanied by "rattling" sound.
Homes nearby residents are somewhat removed from the funnel and it will not cause much harm. But still there is a risk of collapse in the event of rain, as the edges of the hole cracks.
