Geologists have determined four main factors as the root causes of the deadly landslide in Zhouqu county of China's north-west Gansu Province. The main trigger was the heavy rains this summer that has weighed down the soil.

Secondly, Zhouqu is made up of a unique kind of landform that is highly susceptible to erosion.

Thirdly, Zhouqu was one of the most seriously affected regions of the 2008 Wenchuan earthquake. The structural integrity of mountains in the vicinity were jeopardized as a result.

And lastly, geologists claim that the ongoing drought has increased the size of crevices found in the region's many rock formations.
