Final disposition of your abstract will be e-mailed to you by 31 August.

Topical Sessions

All sessions will take place at the Oregon Convention Center,
777 NE MLK, Jr. Blvd., Portland.

Invited and Volunteered Papers

These sessions are topically focused with a mix of invited and volunteered papers. Sessions are designed to promote the exchange of interdisciplinary, state-of-the-art information.

Can’t find a topical session that fits your abstract?

No problem! In addition to the topical sessions, there will be quite a few discipline categories for which you can submit an abstract. Discipline sessions are equally vital to our technical program. Please feel free to contact the JTPC member associated with your discipline if you have any questions regarding your abstract.

T36. Living with Volcanic Lakes: Geologic and Limnologic Tools for Disaster Management
GSA Limnogeology Division; GSA Geology and Health Division
Michael Rosen, Carol Stewart

Volcanic lakes are beneficial but also have risks. This session will focus on impacts of volcanic hazards on water supplies, how abrupt changes can affect the sedimentary record of lake deposits, and how to determine recurrence intervals for hazardous events.

Neotectonics/Paleoseismology; Volcanology; Public Policy

T63. Hydrothermal Systems and Volatile Emissions of Volcanic Arcs
GSA Hydrogeology Division
Cynthia Werner, Shaul Hurwitz, Johan Varekamp, Adam Simon

This session focuses on hydrothermal and volcanic emissions in volcanic arcs, both subaerial and submarine. Topics include field studies, experiments, and modeling related to volatile budgets, magmatic/hydrothermal processes, groundwater flow/chemistry, and global contributions. Oral.

T64. Physics of Volcanic Eruptions: Implications for Hazards
GSA Geophysics Division; GSA Quaternary Geology and Geomorphology Division; GSA Structural Geology and Tectonics Division
Larry G. Mastin, Donald B. Dingwell, J. Kelly Russell

This session explores the physical processes involved in volcanic eruptions and the effects of these processes on hazards. We encourage process-oriented field, laboratory, theoretical, numerical, and instrumental studies with significant implications for hazards studies.

Volcanology; Quaternary Geology; Petrology, Experimental

T65. Supervolcanoes, Ignimbrite Flare-ups, and Their Impacts: Definition, Debate, and New Developments
Shan de Silva, Ilya Bindeman, Jake Lowenstern

Super-eruptions are thought to be the most devastating of terrestrial geologic phenomena with extreme impacts on the earth system that still remain to be fully understood. This session critically examines definitions, new developments, and the current debate

Volcanology; Petrology, Igneous; Environmental Geoscience

T79. Eocene to Early- Miocene Magmatic Evolution of the Northwest United States with Emphasis on the Distribution, Composition, and Petro-Tectonic Setting of Large Rhyolite Systems
Mineralogical Society of America; GSA Structural Geology and Tectonics Division
Martin Streck, Mark Ferns, Paul Olin

This session aims to bring together researchers interested in the volcanic history of Oregon and adjacent states prior to the onset of Columbia River Basalt magmatism. We seek contributions on any aspect of volcanism, petrology, and volcanic stratigraphy.
