  • Do you think San Diego, California's southmost city would be ok?

  • @Hightrain12 Depends on the size of the eruption and direction of prevailing winds. I think Las Vegas would be in more trouble than San Diego.

  • @Hightrain12 Probably, but it really depends on the intensity of the eruption and prevailing winds. Some ash would probably fall.

  • How at risk might the San Fransisco bay area, or the state capital (Sacramento), be be from a Long Valley eruption?

  • @markdzima It would be awful, although I expect that prevailing winds would carry most of the ash east.

  • You should look up Mt Uturuncu in Bolivia (I think). That's my bet for the next very large eruption. They are tracking a large volume of magma growth, which may have potential to erupt. There was an interesting paper by Steve Sparks on it, and I know they are studying it in detail at Bristol University.

  • @Webofscience I've heard about that. And I may have mentioned it in Part 5 of this series. I can't recall for sure because I did this series over a year ago and haven't watched it lately.

  • Thank you for sharing your knowledge and video's for us to see.

  • what are the causes

    

  • @Hightrain12 would los angeles be ok from this eruption?

  • do scientists have a good idea about why there is so much crustal stretching b/w the rockies and the sierras? it seems counter-intuitive what is happening between two large mtn ranges in the middle of a continental plate.

  • you are good they had a earthquake warning on 4/16/11 they had a swarm and back to back 4s

  • understand some of it
