Description
Hazards from Volacanoes.. to be aware of  Describe the particular hazards associated with pyroclastic flows, lahars, dome collapses, sector collapses, lateral blasts & toxic gases. o Lava flows  Slow, usually not dangerous  Easy to predict flow path  Usually mafic + low viscosity o Pyroclastic falls (ash fall)  Hot ash + gas ejected from volcano  Breathing in ash can be deadly  Total darkness  Roofs can collapse  Engines stuck in ash, windshields scratched, turbulence  Weather effects o Pyroclastic flows  Avalanche of pyroclastic material, air, and gas  Driven by gravity  Velocity = 40-400 km/hr  Move even in water o Lahars (volcanic mud flows)  Volcanic debris flow  Water and lose volcanic debris  Prevalent at snow-clad and ice-clad volcanoes o Sector collapse – debris avalanche  Sometimes a volcanic edifice
