Yungay Landslide. The landslide around 200BC which formed Lake Waikaremoana on the North Island of New Zealand, where a large block of the Ngamoko Range slid and dammed a gorge of Waikaretaheke River between the Ngamoko and Panekiri ranges, forming a natural reservior up to 248 metres deep.

Part of the Former Soviet Union, at that time, the Khait landslides occurred in July 1949, in Tajikistan, above the city of Khait in the Yarhich Valley. [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.

How did the landslide trigger the eruption of Mt St Helens? 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.

This landslide killed all but one of the 577 people in the town of Deixi. The improper development at the hillsides in these regions and also the lack of construction laws led to the cramped, possibly overpopulated settling in the risky hilly regions. Vargas Tragedy. Most of the fatalities were caused by numerous landslides triggered by the earthquake. A faint rumbling sound that increases in volume is noticeable as the landslide nears. Estimates of the average annual cost of landslide damage for the urban areas studied are $5,900,000 in the San Francisco Bay area; $4,000,000 in Allegheny County, Pa.; and $5,170,000 in Hamilton County, Ohio. Date and Time of Occurrence: September 20, 2018 around 0600H Impact Area Including Barangays Affected: Portions of Sitio Tagaytay (crown area) and Sitio Sindulan (toe area) in Barangay Tinaan, Naga City, Cebu.Northeastern portion of the quarry area of Apo Land & Quarry . The massive landslides were triggered by the 1949 Khait earthquake killing thousands of innocent people. The result is wearing off of the earths surface. Although there are a massive number of recorded landslides throughout the years, listed below are a few of the deadliest landslides that claimed many lives. More than 5,700 lives were lost which was later reported to be 6,054. In July 1949, the M7.4 Khait Received 6 September 2008 earthquake triggered many hundreds of landslides in a mountainous region near the southern limit of the The massive Diexi earthquake in Diexi Mao County, Szechwan, China on August 25, 1933, triggered the Diexi landslides. Regular readers will know that one of my interests lies in trying to get a better understanding of the loss of life associated with landslides. Can major landslides and debris flows happen in all areas of the U.S.? What causes them?

Some 1,221 people died and the barangay of Guinsagon was buried. 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.

Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Landslides occur in a variety of environments, characterized by either steep or . Climate and climate change controls precipitation and snowmelt (frequency, intensity and magnitude, seasonality, cyclonality and the respective changes), and are the most important external drivers for landslides and flooding. The landslide near the rural community of Manti, Utah, caused an expenditure of about $1,800,000 or about $1,000 per person during the period 1974-76.

The geology, historical seismicity, progressive disintegration of the rock mass, development of smectite layers and the continuous development and movement of shears within the Philippine Fault Zone combine in the steep rugged terrain to produce massive landslides, of which the 15 million m3 Guinsaugon event was the latest. The American Geosciences Institute represents and serves the geoscience community by providing collaborative leadership and information to connect Earth, science, and people.

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. Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows. [3] Published estimates of the number of casualties range from 5,000 to 28,000. 2009) re-examining the 1960 Huascaran rock avalanche in Peru.

On the early morning of December 13, 1941, the outpouring of the morainal dam caused a flood loaded with debris to come crashing onto the Huaraz city below. (2003) Rockfall hazard analysis for Hong Kong based on rockfall inventory Rock Mechanics and Rock Engineering, Vol. The Khait landslide was simulated using DAN. The avalanche travelled a distance of 16.5 kilometers. [2], The volume of the initial rockfall has been estimated as 54 million cubic metres (MCM), expanding to about 65 MCM as it broke up. Heavy rainfall caused havoc in the Northern states of India and around June 16, 2013, a series of landslides and floods took over five thousand lives. and P.E. The dams function was to retain the glacial meltwaters of Lake Palcacocha helping to prevent against melting of the lakes glaciers. Just before dawn on December 13, 1941, disaster struck the Peruvian city when a landslide resulted in glacial ice crashing down into Lake Palcacocha, generating huge waves that completely destroyed the dam on the lake. Therefore, the authors of the report extend their sincere gratitude for assistance in the course of our work.
