Question asked by: alioni
Asked on: 25 Feb 2010
Certain types of explosions from volcanoes are what cause this sort of disaster, the pyroclastic flow.
They can move really quickly and be caused by things such as fountain collapse, gravitational collapse of a lava flow and more besides.
Take a look at the wikipedia page on pyroclastic flow for more information on this.
