Xinhua<\/a> describes the event thus: “<\/span>…several hundred tonnes of rocks and dirt gushed down from the mountain at about 9:20 p.m. Wednesday. <\/span>Four workers in charge of a cave-digging project in the hill, the project contractor and his wife were in the houses when the accident took place, the city’s public security bureau said. <\/span>Jiang Mingyi, head of the city’s geological environment monitoring station, said ongoing rain over the past few days triggered the landslide and the local karst-landform is prone to mountain collapse in the rainy season.”<\/p>\n

It would be easy to ascribe this collapse to the caving digging work that was going on at the toe of the slope. However, the failure appears to have occurred on an unfavourably orientated joint high up on the slope. The initial collapse was possibly quite small, but the failure has accrued debris on the way down to create quite a large failure. Thus, the interpretation that the failure was rainfall-induced looks spot on.<\/p>\n

Of course, what is not clear is the degree to which the work at the toe of the slope disturbed the joints upslope. If blasting was being used this is of course quite possible.<\/span>
