The relevance of recent heavy rain and an almost synchronous seismic event are considered but it is concluded that the movement was the result of progressive failures and tectonic weakening while the landslide hazard was increased by the presence of rice paddy fields in the valley bottom. The river is known to have begun cutting the valley through the glacial sediments roughly 12,000 years ago, suggesting an average recurrence rate of about 500 years based on the 25 landslides. This landslide triggered a gigantic tsunami in which a tremendous amount of water overpowered the dam in an 820 feet wave devouring and destroying the Piave Valley below with the terrible flooding. More recently, the U.S. Geological Survey estimated annual losses to be between $2 billion and $4 billion per year. Although heavy rainfall affected other states like Haryana, Delhi, Himachal Pradesh, and Uttar Pradesh almost 90% of the fatalities were associated with Uttarakhand. Haiyuan County alone lost more than 50% of its population in the disaster. Huaraz Debris Flows, Ancash, Peru, December 1941 (5,000 deaths), 6. Causes of landslides include earthquakes, deforestation, and erosion. In a typical year in the United States, expansive soils cause damage to more homes than earthquakes, floods, hurricanes, and tornadoes combined. The worst affected areas included the the epicenter of the earthquake in the Haiyuan County in what is now the Ningxia Hui Autonomous Region, as well as the neighboring provinces of Gansu and Shaanxi. In terms of total natural damage claims, storms cost Norwegian insurance companies the most but landslides result in far greater single payouts. The area covered by the Yasman valley slide is about 24.4km2, with a total estimated volume of 245 MCM (million cubic metres).

In January of 1962, a thaw triggered the breaking off of a portion of the north summit of the mountain, leading to a landslide/avalanche that led to the tragic death of nearly 4,500 people. This was a Mw=7.4 event on 10th July 1949 in the Tien Shan mountains of what is now Tajikistan, but was then the Soviet Union. Deadliest Landslides In Recorded History. Landslides can be caused by natural or human events. [2] At the same time the Tajik Basin is being shortened in response to oblique collision with the Pamirs, forming a series of north-south to SW-NE trending thrust faults, the earthquake is thought to have been caused by movement on the Vakhsh thrust, one of these faults. 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. Neighboring villages also suffered the consequences due to the debris that came down with the landslide. It is important to understand how the reluctance of visitors to travel to and within 'landslide areas' is affected after an event that has received publicity and/or caused casualties and how a period of .
