T13F:
New Insights into the Active Deformation, Tectonic Evolution, and Hazard Mitigation of the Caribbean Plate and South America II


Session ID#: 10719

Session Description:
This session seeks to discuss the current state of knowledge of Caribbean plate geodynamics, kinematics and tectonic evolution. Recent studies have quantified how strain is accommodated along the plate boundary, have been able to better constraint geological hazards, and have postulated new models to explain its tectonic evolution. The Caribbean Plate is tectonically active with subduction zones, volcanism, and transpressional zones that produce large seismic and volcanic hazards. The densification of seismic and geodetic instrumentation, capacity building, international collaborations, and collection of new data sets during the past decade are improving our understanding of the Caribbean plate. We seek contributions that use geophysical (seismic, geodetic, remote sensing), numerical and/or analog modeling, and geological techniques to understand strain accommodation along active faults, earthquake, tsunami and volcanic hazards, subduction processes, deformation history, and plate kinematics. This session also encourages contributions on future research directions on tectonics of the Caribbean Plate.
