University of Memphis - Department of Earth Sciences

Research in these foci are carried out, in part, through cooperative work with the Center for Earthquake Research and Information (CERI), the Groundwater Institute, the FedEx Institute of Technology, and the office of the U.S. Geological Survey, located on the main campus, as well as with other departments such as Biology, Chemistry, Anthropology, and Civil Engineering.

Hazards (coordinator: Arleen Hill)
More than twenty DES faculty members and their graduate students do both applied and basic research related to the principal DES research-focus: Hazards. Their research is intertwined under the auspices of the Center for Hazard Analysis and Research at Memphis (CHARM) and CERI. CHARM is unique in the USA in the large number of diverse faculty devoted to research on all aspects of multi-hazard analysis. CHARM is capable of comprehensive integrated coverage of all important aspects of natural, environmental, and man-induced hazards from understanding the basic causes of hazards through application of multi-hazard-susceptibility analysis to different regions, to the catastrophic impact that hazards have on people through vulnerability and risk analysis, to hazard mitigation, to determination of the economic and policy impact of hazards.

Basic research in Geophysics related to earthquake-hazards is the principal function of DES faculty at the Center for Earthquake Research and Information (CERI). Faculty from all DES disciplines are also engaged in basic research on Active Tectonics & Orogenic Belts and Quaternary Studies & Geomorphology which also includes investigations related to landscape evolution, climate change, and paleoecology as well as those related to the causes of natural hazards such as active faults, landslides, flooding, drought, severe storms, and subsidence & karst development. Through the Hydrology & Water Resources focus, in cooperation with the Groundwater Institute and the U. S. Geological Survey, DES faculty examine both environmental hazards and other issues related to vital water resources. CHARM faculty apply basic hazard-research and Spatial Analysis to determine both the susceptibility of different regions to different types of hazards and to vulnerability and risk analysis, both fundamental tools for planning sustainable growth and development, particularly of urban areas, while protecting people from multi-hazards. New faculty members who join DES in 2003/04 academic year expand CHARM capabilities into vulnerability and risk analysis and also examine motivational behavior during emergencies, economic costs related to hazards, and policy issues related to multi-hazards.

Faculty who work on hazards include: Arleen Hill, Jerry Bartholomew, Paul Bodin, Melissa Checker (Anthropology), Jer-Ming Chiu, Randy Cox, Chris Cramer, Mike Ellis, Joan Gomberg, Arch Johnston, Hsiang-Te Kung, Chuck Langston, Esra Ozdenerol, Chris Powell, Jose Pujol, Paul Rydelek, Buddy Schweig, Bob Smalley, Lensyl Urbano, Roy Van Arsdale, Thad Wasklewicz, Mitch Withers, and Jungyul Sohn, who will join us in June, 2004.

Faculty who work in geophysics include: Paul Bodin, Jer-Ming Chiu, Chris Cramer, Mike Ellis, Joan Gomberg, Arch Johnston, Chuck Langston, Chris Powell, Jose Pujol, Paul Rydelek, Bob Smalley, Lensyl Urbano, and Mitch Withers.

Active Tectonics & Dynamic Geomorphology (coordinator: Roy Van Arsdale)
Our faculty offer unique opportunities to students who are interested in tectonics related to active deformation and plate motions. Active tectonics projects are being conducted in the United States, South America, Australia, Antarctica, Central America, Caribbean islands, China, Africa, and India. A long standing area of focused research has been the New Madrid seismic zone of the central United States where DES student and faculty have conducted seismologic, seismic reflection, paleoseismologic, structural, and stratigraphic studies.

The geomorphic research focus centers around four general themes: tectonic, fluvial, arid, and hill slope processes and forms. Building from a foundation of these general areas, The research is international in scope and includes studies in China, Australia, Central America, the Caribbean, Malaysia, India, Taiwan, and numerous locations in the northeastern, southeastern, and western United States.

Faculty members and their graduate students who study tectonics and geomorphology within the Department of Earth Sciences take advantage of interdisciplinary research with the U.S. Geological Survey and other academic departments within the University of Memphis. Students can also participate in tectonic studies in classic orogenic belts such as the Appalachians, Cordilleran, Ouachitas or Grenville or within the cratonic interior of North America. Basin studies may be pursued using recently acquired Landmark Graphics software. This software is particularly suited for petroleum-related research, but is also being applied to earthquake and groundwater studies.

Faculty members involved in tectonic studies include: Roy Van Arsdale, Jerry Bartholomew, Paul Bodin, Jer-Ming Chiu, Randy Cox, Michael Ellis, Joan Gomberg, Archibald Johnston, Hsiang-Te Kung, Charles Langston, Daniel Larsen, Jose Pujol, Chris Powell, Eugene Schweig, Paul Rydalek, Robert Smalley, Thad Wasklewicz, and Mitchell Withers.

Hydrology & Water Resources (coordinator: Lensyl Urbano)
The Department of Earth Sciences offers a focus in Hydrology that builds upon faculty strengths in the physical, biological and human aspects of the hydrologic cycle. Our specialties include modern and paleo- hydrogeology, landform evolution, wetland ecology, large river ecology, aqueous geochemistry, water resource management, hydrogeologic modeling and the impact of climate change on water resources. Our proximity to the Mississippi River contributes to our expertise in large river hydrology and enables international collaboration on water resource management and issues related to large river systems. The location of Memphis in the Mississippi embayment, with its exceptional high-quality aquifers, provides excellent urban and natural laboratories for hydrogeologic research, particularly given our close collaboration with the Groundwater Institute, housed in the Herff College of Engineering here at the University of Memphis. Faculty and researchers involved in the Hydrology focus also include members of the Biology Department, the US Geological Survey and the Center for Earthquake Research and Information.

Faculty who participate in Hydrology and Water Resources include: Lensyl Urbano, Jerry Anderson (GWI), Scott Franklin (Biology), Jack Grubaugh (Biology), Hsiang-Te Kung, Dan Larsen, Reza Pezeshki (Biology), George Swihart, Brian Waldron (GWI), and Thad Wasklewicz

Geoarchaeology & Quaternary Studies (coordinator: David Dye)
With the merger, effective with the fall semester of 2004, of Archaeology faculty into the Department of Earth Sciences, we now offer a research focus in Geoarchaeology which interweaves geologic techniques, GIS, remote sensing, and geophysical techniques into Archaeology research. Quaternary studies branch out to investigate landscape evolution, climate change, paleoecology, and active tectonics over the last two million years. Research activities include field, laboratory, geographic information analysis, and modeling studies that focus on the timing, causes, and mechanisms of natural and anthropogenically forced climate change, and on the effects of past climate changes on the physical, biological, chemical, social, and economic conditions of the earth.
