  • Distribution of Tectonic Hazards
    • Tectonic Hazard - natural event that has the potential to threaten both life and property
      • uneven distribution across the globe and can happen at any plate margin
      • earthquakes can also happen where the Indo-Australian plate collides with the eurasian Plate - a collision zone
    • Intra Plate Earthquakes and Volcanoes
      • Hotspots - hot mass of rising heat under a weakness in a plate, magma rises to the surface e.g the Hawaiian Islands in the pacific
      • isolated plumes of convecting heat in the mantle rise towards the surface generating basaltic volcanoes - the plume is stationary although the tectonic plate moves
        • continuing plate movement over time produces a chain of volcanic islands
      • Earthquakes can happen in mid-plate settings, usually associated with ancient fault lines being reactivated by tectonic stresses - zones of weakness are created as plates move and stresses increase
