  • Volcanoes
    • Tectonic Processes
      • Conservative
        • Frequent but calmer eruptions
        • Plates move apart
      • Destructive
        • Plates move together
        • Violent dangerous -pyroclastic flow
      • Hotspot
        • Not found at plate boundaries, can be super eg  Yellowstone
    • Why eruptions vary
      • Viscosity of magma
        • The more viscous the magma the greater the potential for explosive eruptions
      • Proximity to population
        • Volcanoes near big settlements cause more damage
      • Types of materials ejected
        • Pyroclastic flow
        • Ash clouds
        • Lahars (ash and water)
    • Impacts
      • Economic
        • Can bring tourism
        • Ash fall disrupts air travel
        • Workplaces and therefore jobs lost
      • Environmental
        • Land on flanks is fertile
        • Ash smothers crops
      • Social
        • Loss of possesions
        • Ash fall causes breathing problmes
        • Deaths injuries
    • Short term Reaction
      • Evacuation
      • Search and Rescue
      • Emergency food shelter and water
      • First Aid
    • Long term plans
      • Educate locals and tourists alike
      • Prediction
        • Measure gases
        • Measure bulges
        • Measure small tremors with seismometer
      • Make an evacuation plan
      • Install a warning system
