hope it's help you thank youExplanation:The mountain areas are more vulnerable to natural disaster due to its varying nature of relief where the developmental activities over the years has further accentuated the problem by upsetting the natural equilibrium of various physical processes operating in the mountain eco system. A disaster is defined as the outcome of a hazard negatively impacting a social ecological system [1], [2]. The magnitude of the disaster is directly RELATED with the intensity of the hazard as well as with the exposure and the vulnerability of the socialecological system [3]. However the disasters could be assessed in many ways: number of deaths, number of building collapsed, kilometers of roads destroyed, money loss due to the disruption of economic activities. Disasters often nullify the efforts and hard work of several years in a matter of hours and even minutes and seconds. In the present scenario the state of Uttarakhand is more vulnerable to disasters and has been devastatedrepeatedly by a number of hazards that include both geological and HMD. The climatologist and environmentalist are in the opinion that the frequency and amplitude of natural disasters have increased in last 30-40 years due to variations in the climatic parameters. The anticipated increase in precipitation, the melting of glaciers and expanding seas have the power to influence the Indian climate, with an incidence of floods, drought, flash floods, storms, cloud burst. The impacts on river flow, groundwater recharge, natural hazards, and the ECOSYSTEM, as well as on people and their livelihoods, could be dramatic, although not the same in terms of rate, intensity, or direction in all parts of the region [4]. The substantial PORTION of the annual precipitation falls as snow, particularly at high altitudes (above 3000m) feeding the Himalayan glaciers. The high Himalayan and inner Asian ranges have the most highly glaciated areas outside the Polar Regions [5], [6]. Globally, the climate change is very likely to increase the pressure exerted by non-seismic hazards. The high temperatures will enhance the hydrological cycle and it is predicted that they will alter rainfall PATTERNS and intensity [7].
