Volcanoe's Parts      Sill                Flank                Summit                Dike                Conduit                Resevoir                Vent                Throat                Crater                Base                Lava           Hazards      Gas           - Sulfur Dioxide gas creates air pollution     that irritates skin, nose, throat, and eyes           - Carbon Dioxide is so concentrated that it kills animals and humans           - Acid rain that some times takes the form of Hydrochloric acid      Lahars           - hot or cold mixture of water and rock fragments, often resembles a flow of concrete           - hundreds of meters wide, tens of meters deep           - flows at several tens of meters a second (too fast to outrun)      Landslides           - large rocks or debris falling rapidly downhill           - if the landslide contains enough water it will transform into a Lahar      Lava flows           - lava thats errupted during non explosive periods           - can travel up to 10 km / hour           - can result in lahars      Pyroclastic Flows           - high density mixtures of hot, dry rock fragments and hot gases that move at high speeds           - can result from non explosive or explosive periods of the volcano's history           - can result in lahars      Tephra           - gas clouds that are carried several hundreds of kilometers from the vent           - can disrupt machinery and lives very far away from the volcanoe Parts      Sill                Flank                Summit                Dike                Conduit                Resevoir                Vent                Throat                Crater                Base                Lava           Hazards      Gas           - Sulfur Dioxide gas creates air pollution     that irritates skin, nose, throat, and eyes           - Carbon Dioxide is so concentrated that it kills animals and humans           - Acid rain that some times takes the form of Hydrochloric acid      Lahars           - hot or cold mixture of water and rock fragments, often resembles a flow of concrete           - hundreds of meters wide, tens of meters deep           - flows at several tens of meters a second (too fast to outrun)      Landslides           - large rocks or debris falling rapidly downhill           - if the landslide contains enough water it will transform into a Lahar      Lava flows           - lava thats errupted during non explosive periods           - can travel up to 10 km / hour
