The volcanoes in the Andes are generally fed by very viscous, gas-rich magma. The gas is kept dissolved in the magma under enormous pressure. When the magma is close enough to the surface the lower pressure allows the gasses to come out of solution violently. This is what makes these eruptions explosive.
