Comment on this resource
This resource presents three examples of lava domes, from Alaska, Japan, and Saudi Arabia, along with a 3D simulated view of Mt. St. Helens' lava dome. A diagram shows the progressive growth of Mt. St. Helens' lava dome from 1980 to 1983. A link leads to a thorough explanation of dome-collapse pyroclastic flows (nuee ardentes) and another leads to a numerical program of lava dome growth.
