A review of “8.8” debris flow in zhouqu

Abstract

The August 8, 2010 (henceforth 8.8), massive debris flow in Zhouqu shocked the world with its huge losses. Site investigation and research showed the 8.8 massive debris flow in Zhouqu to be both a natural disaster and a human calamity. This debris flow disaster has six characteristics: heavy loss caused by bursting at midnight, a quickly induced disaster after sudden rainfall, a lack of alertness for light rain beyond the mountains, great magnitude with strong disruption, erosion inside the gully while burial outside, and aggravating loss owing to a chain effect. Both natural conditions and artificial factors led to the outbreak of this massive debris flow. .
