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!
