Things not so hot where you live? Wouldn’t you rather be outdoors in Hawaiʻi with a field notebook, studying active volcanoes? Imagine living in Hawaiʻi surrounded by erupting volcanoes, lush rainforests, high mountain peaks, and the tropical waters of the Pacific Ocean. This could be your life if you enroll at the Geology program, or the Natural Science program, at the University of Hawaiʻi at Hilo. We offer an affordable undergraduate education with small classes and personalized instruction. Visit our Mentos page, which explains how the famous Mentos & Diet Coke explosions work, and how expanding gas relates to volcanoes.

UH Hilo Geology majors in Ken Hon's Volcanology class obtain lava temperatures with a thermocouple. A film crew records the students at work, for a television documentary.
