Volcanoes Around the World

  • Volcanoes around the world (Kilauea, Rainier, Mazama, Yellowstone, Long Valley) erupt magmas with differing silica contents - and therefore have constrasting eruptive styles. Eruptive styles range from effusive and quiet...to explosive and deadly. And there is a global pattern for the location for these volcanoes.
    Magma chemistry (silica content) is an important factor in determining the location and eruptive danger for volcanoes in the Cascades, the Andes, and other locations. Sheild volcanoes (45% silica), Stratovolcanoes (60% silica), and Supervolcanoes (75% silica) demonstrate contrasting volcanic shapes, locations, and eruptive styles.
    Tom Foster (HUGEfloods.com) and Nick Zentner (Central Washington University) have been hiking together in eastern Washington for years. ‘Volcanoes Around the World’ is part of a “2 Minute Geology” video series.

    Thank you for another great video. I realise it's a lazy way (perhaps?) to learn about geology, but when you have a busy life, it's great to have this option. So thanks and keep up the good work.

    I have been greatly fascinated by volcanoes. Learned new things from your video.

    Became a subscriber a little while back because of WildwoodClaire1.
    Absolutely loving your videos.

    Funny how this "2 minute" Geology, lasted for 4 minutes... Still brings up some good questions.

    Did Pennsylvania, once have volcanos ?

    very very interesting as usual!
    Can anyone link the soundtrack of this video?

    • @Ellensburg44
      @Ellensburg44 Před 9 lety

      Anri Giorgadze Thanks for watching. Not sure what you mean about linking the soundtrack...

    Good video, if a bit over-simplified. Many volcanoes have alternated between explosive, Plinian eruptions and effusive eruptions in which magma slowly poured out of fissures. For example, the last several eruptions in Yellowstone were effusive.

      Thanks for watching, Claire. Yes, plenty of exceptions globally, but wanted to introduce the general pattern.

    • @ReedBetweenTheLines

      Oversimplification aside (Who would I be to criticize that anyway?), thanks for shouting out this channel Claire.
      I'm learning a lot, and the host is very likable. Makes it easy for a neophyte like me to understand.

      Yea, Wildwood, a four minute video meant for a nonprofessional audience should have given full coverage to every nuance of the subject matter, using incomprehensible jargon whenever possible.

    ahora entiendo como se formaron las capas de toda la tierra, excelente video, gracias

    Leave it to a geologist to use shale and chock still, instead of a white board and dry erase markers.

      Old school slate and chalk, buddy! Hiking with a slate board - I've had better ideas.

    I still have my hammer..! What’s a subduction zone doing here in eastern Washington?

    • @Ellensburg44
      @Ellensburg44 Před 6 lety

      Jealous. Who said there was a subduction zone in eastern Washington?

    • @dvnprtjoe9
      @dvnprtjoe9 Před 6 lety

      Nick Zentner I don’t think you can crack a hammer and still use it..! Geology and mineral deposits of the Turtle lake Quadrangle Washington. Becraft and Weis, 1963. Below the chocolate cake. Oh boy..! Sanpoil volcanics, Where’s the ice cream?

    Thumbs up for field chalkboards.

    I'm 43 years old, been watching science documentaries my whole life. Best concise explanation of volcanoes I've ever seen. Keep up the good work, sir, and please contact me if you want to collaborate, I'm a filmmaker - starmountainmedia.com/demo.html
