If you’ve ever wanted to know how vulcanology works, visit the virtual Alaska Volcano Observatory (AVO). Here you can see a history of the seismology, look at the web cams (even inside the volcano), and receive weekly reports on volcano conditions. You also can get information on how to collect an ash sample for AVO. This is a great use of the web for lay scientists and anyone who wants a user friendly introduction to the workings of a volcano.
