Snowpack on the western flank of Tokachi preserves individual layers of pyroclastic surge and pyroclastic flow deposits from the 1988-89 eruption. Because the eruptions took place during the winter, snowfall proved very useful to scientists in distinguishing the deposits of small-scale eruptions that lasted only a very short time.
