  • LEDC Volcano Case Study: Montserrat
    • Background
      • British colony in the Caribbean.

      • Volcanic bombs were hurled. e.g. in Bethel, rocks of 5 metres in size landed.
      • Ash covered 2/3 of the island.
      • The dome collapsed resulting in 5 million cubic metres of ash and dust (pyroclastic flows in several directions) enveloping the surrounding area.
    • Effects
