February 17, 2021
Virtual

Date: February 17, 2021
Speaker: Dr. Jacob Lowenstern, U.S. Geological Survey
Title: Volcanoes, Calderas, and Eruptions: What we Know and What we Don't Know
Time: 1:00 PM Eastern Time (US and Canada)

Abstract

In this talk we will explore the basics of our understanding of volcanoes, magma chambers, and volcanic eruptions. We will focus on three topics: 1) Our basic understanding of volcanoes and earth melts, 2) Tools for understanding volcanoes and the Earth's crust, 3) and how we forecast eruptions. Some specific volcanoes discussed will include Yellowstone (Wyoming/Montana/Idaho), Agung (Bali, Indonesia), Ijen (Java, Indonesia), and Medicine Lake (California).

Biography

Jake Lowenstern is a research geologist with the U.S. Geological Survey in Vancouver, WA. He serves as the Chief of the Volcano Disaster Assistance Program, which is a partnership of the USGS and USAID's Office of U.S. Foreign Disaster Assistance. From 2002-2017, he served as Scientist-in-Charge of the Yellowstone Volcano Observatory. To study the interaction of magmas and their overlying hydrothermal systems, he applies techniques ranging from gas and isotope geochemistry to igneous petrology to U-Th-Pb geochronology. A 1986 graduate of Dartmouth College, he spent the following year on a Fulbright fellowship to Catania Sicily (Italy). He later earned an M.S. and Ph.D. at Stanford University, finishing in 1992. He spent a year as a researcher at the Geological Survey of Japan (Tsukuba) in 1993. Since then, he has worked for the USGS in Menlo Park, CA. In 2000, he received the Lindgren Award from the Society of Economic Geologists and in 2006 was an AAPG Distinguished Lecturer. He was elected a fellow of the Geological Society of America in 2011.
