Document Summary
Positive effects of volcanic activity (geothermal energy )- provides nutrients to soil, tourism, creation of new land and building materials (granite). Geothermal energy- energy harnessed in areas where water is heated to temperatures over. Slope- the degree of rise or fall on the mountain. Rock structure- joints dipping downslope usually assists landslides, rockfalls, rockslide, rock creep. Vegetation- lack of vegetation cover to hold loose particles. The moving material must be loose and capable of flow and half of the solids in the mass must be larger than sand grains. The speed of a derbis flow can reach up to. Rock slope protection- placing a layer of loose rock or aggregate over erodible soil surface. Terracing- converting a slope into a series of horizontal step-like structures in order to control the flow of surface runoff by guiding runoff across slop. Diversions- ridges of soil or channels with a supporting ridge on the lower side.
