91 missing from landslide that buries buildings in China
....
Details are beginning to emerge about the cause of the landslide, which authorities say covered an area of 100,000 square meters (1 million square feet) with up to 6 meters (20 feet) of mud.
The Ministry of Land and Resources said the debris originated with a steep, man-made mountain of dirt, cement chunks and other construction waste that had been piled up against a 100-meter (330-foot) -high hill over the past two years.
Heavy rains in the region had saturated the soil, making it increasingly unstable and ultimately causing it to collapse with massive force.
“The pile was too big, the pile was too steep, leading to instability and collapse,” the ministry said, adding that the original, natural hill remained intact.
The Ministry said it had dispatched additional personnel to help monitor the situation and guard against a second collapse.
