For the 100th episode of Blue Dot we go volcanic! Dave interviews Erik Klemetti, Professor of Geosciences at Denison University in Ohio. Klemetti is an expert volcanologist who writes about volcanoes for the Discover Magazine blog Rocky Planet. We'll talk about the ongoing and unfolding saga of the Kilauea Volcano's eruptions on the big island of Hawaii. In the second half of the show, we visit with three California State University Chico students who are doing volcanology research as undergraduate students under the guidance of Professor of Geosciences at CSU Chico, Rachel Teasdale. Two of the students, Amy Robson and Angie Rodriguez, are researching the hydrothermal system at Lassen Volcanic National Park and Evan Davis is modeling a lava flow emplacement on Mars. Dave also talks to their mentor about the value of having undergraduate students do high level scientific research projects.
