Session ID#: 16608

Session Description:
Active tectonics research involves the measurement of spatial and temporal patterns of crustal deformation throughout the earthquake cycle. A better understanding of the complexities with which tectonic strains are accumulated and released requires the combination of investigations that span different spatial and temporal scales. It requires precise information on when, where, and how much strain is accumulated (and released)–and that over multiple time-scales. 

 

The rapidly increasing availability of high-resolution topographic data–derived from lidar surveys or photogrammetric approaches–provides unprecedented opportunities for precise (and quantitative) investigations of surface deformation. Combined with improved Quaternary dating methods, these new geomorphic constraints enable us to quantitatively understand multiple time scales of deformation, from millennial tectonic strain accumulation processes to occurrence and recurrence characteristics of historical earthquakes.

 

We welcome contributions that apply high resolution topography and/or dating approaches to questions quantifying active tectonics and geomorphic processes.
