The consequences were disastrous with the forming of an inland tidal wave, the force of the fall was so terrible that the atomic bomb type of powerful gust of air crushed the city of Longarone with only 30 children managing to survive. Estimates based on likely population densities in the two settlements that suffered the most damage, Khait and Khisorak, suggest that only about 800 people are likely to have died directly as a result of the landslide. The 50,000 landslides at the epicenter of Haiyuan County (today called the Ningxia Hui Autonomous Region) with the widespread breaking of the ground led to a series of aftershocks that lasted three years. Climate and climate change. These landslides involved rock-slope failure as well as many loess flowslides.

On the basis of data from other sources, the estimated annual damages on a per capita basis for the City of Los Angeles, Calif., are about $1.60. Ground Shaking & Structural Failure The landslide became more mobile once it began to entrain loess material and reached the Obi-Kabud River where it traversed the floodplain and surmounted a 25 m high river terrace on the river's west bank. A landslide refers to any form of mass wasting characterized by movement of rocks, soil, or other debris downhill assisted by gravity. Of the 8 th International Conf. Huge boulders in the landscape can be signs of past debris flows. Triggered by natural or artificial disturbances, landslides occur along steep sloping regions. The natural calamity which struck the rural district of Haiyuan on the evening of December 16, 1920 claimed over 100,000 lives, and severely damaged an area of approximately 20,000 square kilometers.

Haiyuan County alone lost more than 50% of its population in the disaster. [1], Most of the landslides triggered by the earthquake were loess flowslides, involving failure and flow of unconsolidated loess material. [2], The total distance travelled by the flowslide is 7.4 km. These primary hazards often produce secondary hazards such as ruptured utility lines, hazardous spills, and fires. 'Khait' is a transliteration from Russian: ; local modern spelling: Hoit .
