How many volcanic eruptions occurred since 1956? My son is doing a
report on the OZONE Layer.

Hi Mr. Kent,
There is a recent book called Volcanoes of the World, by Tom Simkin and
Lee Seibert. It has a chronology section listing all volcanic eruptions
up to the end of 1993. I did not count them all. There are about 200
eruptions listed on each page, and I estimate that there have been about
2600 since 1956, including eruptions that are continuous from year to
year. If you want more details you might go to your nearest library and
hopefully they'll have the book. You'll want the 1994 version.
Sincerely,
Scott Rowland, University of Hawaii
