Jim Webster

Jim is fascinated with volcanoes. He wants to know why some volcanoes erupt explosively, and how he might be able to help predict these eruptions in the future. Jim knows that the secret lies within the gases trapped in the magma, which hardens to form volcanic rocks. So he travels around the world to collect volcanic rocks. In the lab, Jim analyzes these rocks and re-creates tiny volcanic eruptions to help solve the mystery.
