Volcano Alert - Earth Science - Will scientists ever be able to accurately predict volcanic eruptions? | DVD

• Volcanoes are among natures most awesome forces.
• Over millions of years, lava and debris ejected from volcanoes have created more than 80 per cent of the surface of our planet and the worlds 1500 currently active volcanoes still kill an average of 800 people per year and threaten the lives of 500 million more.
• We visit the Italian city of Naples, where 500,000 people live in the shadow of the worlds most dangerous explosive volcano Mount Vesuvius.
• We travel around the world, looking at how each volcano prediction method helps scientists complete the jigsaw picture of when an eruption may happen.
• For the newest prediction techniques of all, we look at stunning computer images revealing the structure of magma chambers up to 100 miles under the ground. Nobody has ever seen this deep before.
