- A remote lake in Southeast Asia conceals evidence of Earth s greatest volcanic cataclysm of the last 100,000 years. Miles beneath its placid surface lies a magma chamber that exploded so violently during the Ice Age that gases and ash may have encircled the globe and blotted out the sun for years on end. The Toba eruption may have helped kick the climate into an unprecedented freeze and perhaps ev
DVD Reviews of NOVA: Mystery of the Megavolcano
DVD Review: Informative and easy to watch
Summary: 5 Stars
I've been buying Nova documentaries so my 7-year old son can get some science in his head in addition to the complete list of Transformers and the details of their fates.
This DVD does that job admirably; he watched it quite closely, and after we watched it, it was clear that he understood the material and was enthused about it. He wasn't so enthused about living in a state adjacent to Yellowstone NP, but you can't have everything!
For adults, the material is still compelling, since you'll pick up more than a few interesting details of volcanic geology, how they match volcanic ash to a volano, and lest I forget, that Yellowstone's only 40k years overdue for the most destructive eruption ever.
For adults there's still a few "hmm" moments. For instance, matching ash from remote deposits back to the original "super volcano" plays a major role in the investigation portrayed by the documentary.
However, while there are several excellent scenes when not-matching samples are displayed against each other, when the matching samples are displayed, it's just two photos of the same sample. Ooh, boo, since I was really interested in seeing how an ash sample from many hundreds of miles away matches what they found in the crater. Would it be a match that's obvious to the uninitiated, or is it more like a fingerprint, where you have to know what to look for?
But that's a nit relative to the overall production, which is more than well enough done and met my goals perfectly.
