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!
