Even a small landslide that damages a few homes can cost millions of dollars. The landslides completely buried the towns of Carmen de Uria and Cerro Grande, many homes were washed into the ocean. The event, known as the Diexi Slides, claimed more than 3,000 lives, and destroyed many villages within the affected region. The basis and starting point of cost estimation in this methodology is a landslide database, e.g., the one maintained by our working group (cf. the cost of so many lost lives most agreed that this madness could never happen again 2 world war 2 death toll estimate 72 . The timing and location of this event, soon after the war in an area about which the Soviet Union was very secretive, has meant that it has been very difficult to determine any details about the landslides that were triggered in the earthquake. Before they can be expected to take action, local governments need to have an appreciation of costs of damage in their areas of responsibility and of the reductions in losses that can be achieved. Lidar studies conducted before and after the 2014 Oso slide revealed 25 landslides up and down the Stillaguamish River Valley. You also have the option to opt-out of these cookies.

Such simple measures could save lives and empower local communities to take some ownership of their level of landslide risk. Erosion and undercutting of slopes by streams, rivers, glaciers, or waves increase slope angles and decrease slope stability. However, a section of environmentalists, scientists, and the educated public think otherwise. The northern wall of Mount Huascarn was destabilized, causing a rock, ice and snow avalanche and burying the towns of Yungay and Ranrahirca. For the Yasman Valley flowslide they estimate about 4,000 fatalities, and they determine that there were probably a further 2,400 deaths. Heavy rainfall affecting southern Ecuador, particularly the province of Azuay, over the past 48 hours caused numerous landslides resulting in casualties and damage. According to them, thoughtless human intervention in the Himalayan mountain ecosystem had rendered the ecosystem extremely fragile and prone to disaster.

News of the landslide was not publicly revealed by the government and details of the disaster were not revealed until after the fall of the Soviet Union. The Yungay Landslide in Yungay, a rural community in Peru happened on May 31, 1970, due to three different natural disasters. More recently, the U.S. Geological Survey estimated annual losses to be between $2 billion and $4 billion per year. One of the deadliest eruptions of this volcano occurred on May 19, 1919, when over 38 million cubic meters of water were expelled from the crater lake of the volcano, which had accumulated large amounts of sediment and volcanic material to form lethal lahars. The landslide is located on the Kabir Kuh anticline in Southwest Iran at 33 degrees north latitude, 47.65 degrees east longitude. The dam then overtopped, causing a flood and 2,500 deaths.

The debris that traveled a shocking 10.2 miles, carrying 50-100 million cubic meters of mud, ice, and rocks came crumbling down the slope classifying this event as a landslide and avalanche. Much of the debris flow material was deposited before the slide reached the valley bottom, but the frontal part of the slide began increasingly to incorporate loess material and to accelerate. A key realisation of this work for me has been that earthquake-triggered slides cause a very substantial proportional (probably in fact the majority) of fatalities is mass movement events. One of the landslides buried an entire village in Xiji County as well.
