Introduction Modern geophysical techniques of volcano monitoring allow simultaneous observations of a wide variety of parameters relevant to understanding how volcanoes work. Images acquired by scanners and imaging spectrometers are able to important on the surface activity and emissions of volcanoes both during quiescent and active periods, as has been demonstrated by several studies et al. 1990, et 1992, Hobbs 1996). For instance, knowledge of volcanic plume composition and dynamics can provide information on magma movement within volcanic conduits, because S0 2 and C0 2 outputs arc influenced by the magma temperature and hydrostatic within the volcano's internal plumbing. Traditionally, volcanic composition has been investigated by direct sampling, techniques often involving considerable logistical planning and, often, risk. For large volcanoes such as a direct gas sampling from the summit craters is no
