WebThe eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava. A pyroclastic flow is a superheated mixture of hot steam, ash, rock and dust. A pyroclastic flow can travel down the side of a volcano at very high speeds with temperatures over 400 degrees Celsius. Composite volcanoes can rise over 8000 feet. http://www.sci.sdsu.edu/how_volcanoes_work/Lavaflows.html
