Hello, for a school project I am required to analyse a time line which displays the eruption dates of volcanos around the world. I was told that you study volcanos and was wondering if you could provide me with any information or know of anywhere that I could obtain this information.

Dear Muldur,

The Smithsonian Institution publishes the best book on volcano eruptions: Volcanoes of the World by Simkin & Siebert. It includes a diagram (p 28) showing the number of eruptions reported each year since 1790. For the last few decades there have been about 6- eruptions/yr, although large eruptions occur only about once per decade.
