Instructions and help about STANLEY YIP, Appellant Dol

hello everyone my name is stanley and in this presentation i examine the implications of pre-eruptive exhaust volatiles on observations of volcanic deformation and degassing the purpose of this talk is to provide the background information for my poster prior to a volcanic eruption volatiles exhaust into gas phase at depth this process is dependent on melt composition pressure and oxygen fugacity depending on the depressing system of the volcano the exo-volatile phase can either accumulate at the reservoir roof forming a gas-rich cat or the gases prior to an eruption leading to the formation of a the gas plug the volume of exhaust gas in reservoir with a compressibility of magma i would like to emphasize that if demand was gas range we would expect sl to ratio emission and a compressible magma that gives rise to muted ground deformation in contrast as per magma will release low asset to emission and has lower compressibility where ground deformation can be detected so to understand the
