Full Description: Erik Klemetti, assistant professor of geosciences presents a Global Studies Seminar: "Lost Monsters: Forgotten Giant Eruptions and How They Impacted the Planet."Very large volcanic eruptions can have a profound impact on the Earth's climate. They are singular events that can throw billions of tons of volcanic ash and aerosols like sulfur dioxide and carbon dioxide into the atmosphere. However, as large as these events might be, some of the biggest eruptions in the past 15,000 years are unknown to most people. This talk will look at five eruptions from around the globe that are historically obscure but volcanically profound, including very large eruptions in New Zealand (Taupo), Germany (Laacher See), Peru (Huaynaputina), Mexico (El Chichón) and Alaska (White River). These events erupted over 10 cubic kilometers of volcanic ash and debris, making them some of the largest in human history. Eruptions of this magnitude today could have a sizable impact on global travel and agriculture, yet climate and culture have proven to be resilient in the face of these massive events. Free and open to the public.
