What happens to the Earth during a landslide? Almost all of the villages that were mentioned were either destroyed, or almost completely destroyed. The other landslide considered is a very large and complex flowslide that swept down the Yasman Valley, covering about 20 km. It had a magnitude of 7.5 and triggered a series of landslides that together led to 7,200 deaths. The current lack of relevant tools to assess a complex and ever-changing environment in these cross-border areas does not allow an effective assessment of risks and planning for natural disaster mitigation. Mount Huascarn is a famous Peruvian mountain with a snowcapped peak that rises to a height of 22,205 feet. Most of the fatalities were caused by numerous landslides triggered by the earthquake. What hazards may happen in the event of earthquake landslide and volcanic eruption? Although heavy rainfall affected other states like Haryana, Delhi, Himachal Pradesh, and Uttar Pradesh almost 90% of the fatalities were associated with Uttarakhand.

Next in terms of significance are mudflows and landslides for mountainous parts and floods for flatlands. However, some rather speculative reports have suggested that the impacts were very large for example this article in Mountain Research and Development reported a huge landslide at a site that it termed Borgulchak Rock. Unusually for a science paper the article is a ripping-good read. 1933. The areas worst affected were Manila . Approximately 4000 people were killed in the Yasman valley loess flow as 20 villages (kishlaks) were overwhelmed.
