Spring 2012 Colloquia

January 9: Peter Valley, USGS

January 16: Martin Luther King Day, no colloquium

January 23: Flynn Picardal, SPEA. Title: TBA

January 30: Dr Kendra McLauchlan, Kansas State University. Interests: lacustrine sediments, paleoclimate, carbon cycling, climate change. Title: "Changes in terrestrial ecosystems during the Holocene: evidence from paleorecords" website

February 6: Tudor Memorial Lecture, Dr. McNutt, Director of USGS. Title: U.S. Energy Outlook: Whatever Happened to "Peak Oil"? Brown–bag lecture: "Earthquakes Near and Far: A Study in Community Resiliency."

February 13: Prof. Andrew Campbell of the Department of the Geophysical Sciences, University of Chicago, will be visiting us on Monday, February 13. He is the COMPRES Distinguished Lecturer and will present a talk entitled "Composition of the Earth’s Core," COMPRES is the Consortium for Materials Properties Research in Earth Sciences, and you can learn more about it at:

Abstract: The light component alloyed with iron in Earth’s core is responsible for many important physical and chemical properties of the core. Continuing progress in mineral physics experiments, coupled with increasingly detailed seismological observation of the core, is advancing our knowledge of the composition, structure, and dynamics of this inaccessible region of the planet.

February 20: Geoff Bowers, Alfred University. Title: "The ’other’ Scale of Geological Dynamics: Molecular-Level Behavior of H2O and Ions at Mineral-Water Interfaces"

February 27: Bruce Marsh, Johns Hopkins. Title: "Planetary Magmatism: A Competition of Physics and Chemistry"

March 5: Maurice Tucker, Durham, UK. Title: TBA

March 26: No colloquium

April 2: Megan Madden, University of Oklahoma. Title: "Gas hydrates: Reservoirs for water and carbon on Earth and Mars."

April 9: No colloquium

April 16: No colloquium

April 23: No colloquium

April 30: Seth Stein, Northwestern University. Title: "Lessons from Tohoku: why earthquake hazard maps often fail and what to do about it"

Tuesday May 1: Seth Stein, Northwestern University. Title: "What New Madrid shows about intracontinental earthquakes."

Dr. Stein is a seismologist with an incredibly broad range of interests and expertise, ranging from sea-floor tectonics to plate boundary deformation, earthquake source mechanics, and earthquake hazard assessment. He is the also author of the book "Disaster Deferred: A New View of Earthquake Hazards in the New Madrid Seismic Zone," which has placed him at the center of a major scientific controversy regarding earthquake hazards in the central US.
