Doomsday Volcanoes


Doomsday Volcanoes from NOVA

Summary: In April, 2010 the eruption of Iceland's Eyjafjallajökull volcano turned much of Europe into an ash-strewn no-fly zone, stranding millions of travelers. But was Eyjafjallajökull just the start? Now, an even more threatening Icelandic volcano, Katla, has begun to swell and grumble. Two more giants, Hekla and Laki, could erupt without warning. Iceland is a ticking time bomb: When it blows, the consequences could be global. As CGI takes us inside these geological monsters, we meet atmospheric scientists who are working to understand just how devastating an eruption could be—not just for air travel but for the global food supply and for Earth's climate. Could we be plunged into years of cold and famine? What can we do to prepare for the disaster to come?


Angie's Comments: Another cool episode of NOVA. In this case, the focus is on volcanoes in Iceland. The episode explores how much ash, sulfur, and lava have been produced by the volcanoes in the past and the impact those eruptions had on people and the environment. There is less focus on how to prepare for a volcanic eruption. It was interesting to see the different volcanoes, especially going inside the empty lava chamber of an Icelandic volcano. This is a great DVD for anyone interested in volcanoes!
