Resolving tectonic activity with high resolution data in space and time

Session ID#: 71720

Session Description:
Active tectonics research aims to quantify crustal deformation throughout a fault's earthquake cycle. The underlying motivation is often to assess a fault's likely future behavior. High resolution data sets that enable to resolve the spatial and temporal characteristics of co-, post-, and inter-seismic phases of past earthquakes as they are expressed in geomorphic and stratigraphic records.

Recent technological developments have dramatically increased not only amount and resolution of topographic and geophysical survey data sets but also our ability to date stratigraphic units and geomorphic surfaces.  In particular, the availability of high-resolution datasets from LiDAR, SfM, or geophysical surveys, as well as the use of accurate dating methods, such as cosmogenic or OSL dating, allow us to quantitatively study surface deformation at high spatial resolution over large areas and at multiple time scales.

We welcome contributions that focus on methodology and that provide new findings in active tectonics studies.
