Such mudflows occur when ice and snow atop a volcano melt during an eruption and the water combines with volcanic rock weakened by long exposure to heat and water.

On the south side are lava formations of various ages, including the longest continuous lava tube in the 48 conterminous U.S. states, which formed during an eruption about 2,000 years ago.

Volcanic ash that has been ejected higher than 5 km (about 3 miles) during an eruption can be carried by wind and settle out through the atmosphere and oceans as pelagic sediment.

The process that generates this type of PDCs is different from the process that causes by the collapse of an initially convective eruption plume during a magmatic eruption as observed in plinian eruptions, in which changes in physical parameters such as mass discharge rate, vent radius, or magma water content contribute to the decrease in buoyancy and trigger column collapse (e.g., Woods 1988).

These methods open up the possibility to feed (near) real-time monitoring systems with otherwise inaccessible information about vent geometry during an ongoing eruption and help defining important eruption source parameters.
