AGU continued …

Today was a lot of talking and posters. Talking mostly about all things concerning Taupo and Okataina volcanism in New Zealand. Posters ran the spectrum from learning some nifty new tricks to extract zircon crystals from a crushed rock to what happens to clay when you breathe it into your lungs.
I also learned that being head of the Yellowstone Volcano Observatory take a level head and focus (so Supervolcano was a lot closer to the truth than many might think – well, minus the whole eruption).
Speaking of which, Chaiten continues to confound me. The first stuff out in the eruption was actually really crystal poor – something like <1% crystals, which is surprising for such an explosive eruption. Looks like Chaiten might be a once-in-a-century high silica rhyolite eruption … that doesn’t seem to end.

Eruptions Poll results

Thanks to everyone who has responded to my Eruptions poll so far. Looks like we have a couple clear favorites, based on the results right now:

  1. Profiles of historic eruptions – 35%
  2. Profiles of active volcanoes – 33%
  3. Discussion of monitoring techniques – 18%
  4. Discussion of volcanic hazards – 15%
So, I’ll start thinking about some historic eruptions and active volcanoes for the next lull in activity. Thanks for everyone’s input!


Welcome to the inaugural post on Eruptions, a weblog about volcanic eruptions, volcanoes and the people who live near them. I’m going to attempt to compile everything I can about volcanic eruptions currently going on worldwide on this weblog in a hope to foster better understanding of volcanic eruptions, clarify and correct popular media reports on volcanoes and generally hope to get people excited about learning more about the dynamic realm of eruptions. 
As for me, I actively research volcanoes at UC Davis and have a Ph.D. in igneous petrology (the study of molten rocks and volcanoes) from Oregon State University. I have worked on volcanoes from Chile, New Zealand and the United States and find them fascinating. I hope you do, too!
