The Yellowstone Supervolcano
Tuesday February 23rd
Room 417 Schermerhorn Hall
Summary: Over the last 2 million years Yellowstone has experienced three of the most violent volcanic eruptions in Earth's history. What causes these eruptions? How often do they occur? What would be the effects of one of these eruptions if it happened today? Is it possible to predict an eruption? These are some of the questions that will be addressed in the talk.
Mark Anders is an Associate Professor of geology in the department of Earth and Environmental Sciences and a member of the Division of Seismology, Geology, and Tectonophysics at Lamont-Doherty Earth Observatory. His research focusses on continental deformation, particularly normal faulting and crustal extension processes. He and his colleagues and students work to solve fundamental problems in structure and tectonics by employing a wide variety of techniques, including but not limited to: paleomagnetic analysis, isotopic dating (especially Ar/Ar), seismic reflection interpretation, thinsection microscopy, microprobe analysis and mechanical and thermal modeling. Some of recent research topics include: fault growth, continental hotspots and their thermal/mechanical effect on faulting (the subject of this lecture), the paradox of normal faulting, and fault zone studies in the brittle crust. More information on these projects can be found on Mark's Research webpage.
Mark completed his undergraduate degree in Geology at the University of Colorado, Boulder, and his Masters degree in Geology at the University of Michigan, Ann Arbor. He received his Ph.D. in Geology from the University of California at Berkeley in 1989 and promptly joined the department of Earth & Environmental Sciences at Columbia.
Future talks are scheduled for Tuesdays from 12:15-1:00pm in Room 417 Schermerhorn Hall. Attendees are welcome to bring their lunch.
All are welcome to attend!
