hazards of volcanos

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 erupted 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 erupted 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 source : http://volcano...
