However, water vapor is consistently the commonest volcanic gas; as a rule, it comprises more than 60 % of total emissions during a subaerial eruption.

The variety of different volcanic deposits is partly due to changes in eruption characteristics from mainly subaerial eruptions to broadly subglacial eruptions throughout the history of the Northern Cordilleran Volcanic Province.
