Key Info

  • Duration: 02:08
  • Starts by asking why the volcanic ash from the Eyjafjallajoekull eruption in Iceland caused such problems for aviation. This is followed by the theory of a phreatomagmatic eruption in which molten magma hits an ice cap. The resulting rapid cooling of the magma creates shockwaves which create very fine dust which rises high into the atmosphere.
