Abstract The release of gas from ascending magma is one of the most important factors that controls the style of volcanic eruptions. It is proposed in this paper that the viscous resistance of decompressed magma to gas expansion coupled with the lateral gradient of the ascent velocity can work as a driving force of the permeable gas flow that may transport gas in magma toward the country rock. Based on this idea, the rate of gas loss from magma is calculated in terms of the mean ascent velocity… CONTINUE READING
