Geology of Interactions of Volcanoes, Snow, and Water
SUMMARY
Volcanoes in the Cascade Range and Alaska are snow covered at least
part of the year. Most of the northern ones harbor permanent snowfields and
glaciers. All of them have an internal groundwater system; a few of them are
surrounded by seawater. During eruption volcanoes interact with this water,
snow, and ice in many ways, complicating eruptions and generally increasing
hazards to people and property.
