That video is over 2 hours long, I ain't got time for that. Are you able to sum up some of the main points?
The US has 169 volcanoes which are considered active, 55 of which are considered to be serious threats. The threat level of a volcano is determined by
the risk an eruption poses to society. Say you've two volcanoes which are serious threats. One is in the middle of nowhere, removed from civilisation.
The other is relatively close to a town or city. Therefore, the latter would be considered more of a threat, due to its proximity to human
The US lacks adequate monitoring on almost all of its volcanoes, although extensive studies have been undertaken on Yellowstone's super volcano. Not
all volcanic eruptions are equal; they vary greatly in scope and duration i.e., an eruption could last a day, or a week, or a month. A massive
eruption in Yellowstone would blanket most of the country in ash, up to a depth of a few centimetres. Clearly this would have quite a big impact on
farming, transport and communications. However, there is a very low chance of this happening. I think you've got about a 1% chance at most of
Yellowstone's volcano spewing its guts.
And even if Yellowstone experienced a major eruption, it would hardly spell the doom of humanity. It would primarily affect North America. If it's a
big enough eruption, effects may be felt throughout the rest of the world (if it's a really, really big eruption), but those of us happily ensconced
in, say, Australia won't be carpeted in ash.
Most of your volcanic activity is in Hawaii and Alaska. Frankly, you'd be at significantly more risk in Indonesia if one of their volcanoes decided to
puke its guts up.
