The What, Where, and Why of Volcanoes

Speaker: Greg De Hoogh

You know what a volcano is when you see one … or do you? Kilauea, Mt. St. Helens, and Yellowstone are all three volcanoes, but they don’t look much alike and there are other differences that you can’t see. Come find out what volcanoes are, where they form (do you have any idea how many there are in California?), and why they form where they do and act the way they do.

OCM’s President, Greg De Hoogh, is a geologist and would like to share a bit of what he knows with you.

No eruptions are planned for this event, but you’ll learn why, when the next eruption occurs in California, you’ll be better off in Hawaii.
