Earth Surface Processes and Climate Change

G & G scientists are actively studying landscape erosion, sediment transport, and depositional processes in many physical environmental settings. G & G scientist also investigate neotectonics (Neotectonics is the study of dynamic tectonic forces that are actively changing the earth's crust and landscape). G & G scientists collaborate with seismologists, engineers, volcanologists, and other scientists within the USGS and outside organizations to conduct evaluation of landslide and erosion processes and associated hazards, fault systems, earthquake history, and other active natural forces actively changing the modern landscape (such as floods, wave action, wind action, and factors associated with climate change). G & G scientists' work support research efforts with the USGS Landslide Hazards Program, Earthquake Hazards Program, Volcano Hazards Program, and Coastal & Marine Geology Program. Devils Slide along Highway 1 near Half Moon Bay, California
The Devils Slide is an active landslide hazard area along US Highway 1 between Half Moon Bay and Pacific, California.
Climate change studies by G & G scientists include dust hazard investigations throughout the Desert Southwest. Climate-related investigations by G & G scientists also focus on stream channel dynamics, coastal erosion, and effects of wildfire on erosion. A spinoff of surficial mapping investigation has provided insight into biological/geological interactions and the potential impacts of projected climate change on arid and semiarid environments. Resolving detail about climate changes in the geologic past may aide in determining how climate change may effect our future.
