The Story Collider

This week, in honor of Halloween, we're presenting two stories about facing fears for science.Part 1: As a newly minted PhD student in geology, Erik Klemetti starts to question his decisions when Aucanquilcha, a 20,000-foot volcano in Chile, proves difficult to tame.Part 2: Explorer George Kourounis finds himself growing increasingly anxious as he prepares to enter a fiery sinkhole known as the “Doorway to Hell.”Erik Klemetti is an associate professor of Geosciences and volcanologist at Denison University. He works on volcanoes all over the planet, from Chile to New Zealand to the Cascades of Oregon and California. His research focusses on how crystals record the events inside a volcano before and between eruptions. For the past 9 years, he’s been teaching all the “hard rock” classes at Denison. He also writes for Discover Magazine. His blog, Rocky Planet, have been running since Fall 2017. Before that, he wrote Eruptions, a blog about volcanoes, for Wired Science for 9 years.
