  • BENEFITS OF VOLCANIC ACTIVITY
    • ENVIRONMENT
      • SLOW LAVA FLOW - Hawaii, Kilauea - emitting steam & lava since 1983 - added more than 500 acres of land to the island.
      • ASHFALL & LAVA FLOWS - provide mineral deposits => provide fertile land
      • GEOTHERMAL ENERGY - Greysers, California - 1000 megawatts electricity to San Francisco (800,000 residents).
        • Reduces the use of fossil fuels => less CO2 emissions => reduce global warming / climate change.
      • Support a greater variety of plants/crops => enhancing biodiversity.
    • ECONOMIC
      • Mt Etna - land can be farmed by locals & can provide income through crop growth

          • Increases disposible income => increase quality of life.
      • ENERGY PRODUCTION - Geothermal Power - Iceland - 50,000 homes receive energy to heat water
        • ENERGY SECURITY - Reduces dependence on imports fuels.
        • ECONOMIC STABILITY - avoid fluctuating global markets.
    • SOCIAL
      • SLOW LAVA FLOW - Hawaii, Kilauea - emitting steam & lava since 1983 - added more than 500 acres of land. Hawaii - 1.5mn pop.
      • LAND CREATION - Surtsey, Iceland - Use for scientific research.
