Ivy F. Kupec, National Science Foundation Mudslides. Landslides. Volcanic debris flows. Avalanches. Falling rocks... They can come along so suddenly that people, homes, roads and even towns are buried or destroyed without much warning. Recently, we've had dramatic reminders of this, such as the mudslide in Oso, Wash., where 41 people died; an avalanche on Mt.

Volcanic ash is the term for very fine rock and mineral particles less than 2 mm in diameter that are ejected from a volcanic vent. Ash is created when solid rock shatters and magma separates into minute particles during explosive volcanic activity. The usually violent nature of an eruption involving steam (phreatic eruption) results in the magma and perhaps solid rock surrounding the vent, being torn into particles of silt to sand size. The plume that is often seen above an erupting volcano...
