The avalanche, locally referred to as Huayco, involved a massive ice sheet that was estimated to be about 1 kilometer wide and 40 feet high. One such natural catastrophe occurred in July of 1949, when the 7.4 magnitude Khait Earthquake triggered hundreds of landslides near the southern limits of the Tien Shan ranges in central Tajikistan. Landslides occur in a variety of environments, characterized by either steep or . This landslide was one of the most destructive landslides in history. However, landslide costs across the country are not currently tracked or measured in a uniform way by any one agency, so this figure is likely to be an underestimate. The work was determined to be ineligible because there was no damage to the roadway at that time, and there was no apparent immediate threat. The English (UK) government remove Scotland's massive wealth, revenues and resources and send some money back, about 60% of what is removed, as well as making cuts to welfare which is mainly a reserved power to the EngGov (UK) which means that the ScotGov also have to mitigate those (EngGov austerity) cuts to keep people from destitution.

What was the biggest mudslide? [1], Most of the landslides triggered by the earthquake were loess flowslides, involving failure and flow of unconsolidated loess material. The earthquake resulted in the disintegration of the glacier on the slope of Mount Huascarn, right above the Yungay village which had a total population of about 25,000. The January 10, 2005 La Conchita landslide was the deadliest single event triggered by the 2004-2005 storm sequence.

The volcanic flow melted the glaciers in the mountain sending devastating lahars concentrated with volcanic debris of ice, snow, and mud. More recently, the U.S. Geological Survey estimated annual losses to be between $2 billion and $4 billion per year. The average cost of a water damage or freezing claim is $11,098.
