Use of Remote Sensing and GIS in Volcanic Eruption
Sunita Devi
Abstract: Volcano is a vent or opening in the earths crust through which molten material erupts suddenly. Vulcanicity includes all those processes and mechanisms which are related to the origin of magmas, gases and vapour, their ascent and appearance on the earths surface in various forms. Volcanic materials discharged during eruption include gases and vapour, lavas, fragmental materials and ashes. Before an eruption happens, magma moves up towards the ground surface. Volcanologists use several methods to detect the movement of magma like detecting earthquakes, measuring ground deformation, monitoring of volcanic gases, monitoring changes in the chemistry and temperature of greater lakes.
