Subduction Dynamics Across the Scales

Submit an Abstract to this Session

Session ID#: 25133

Session Description:
Subduction zones display a wide variety of tectonic and earthquake behaviors across a range of timescales. Seismic tomography, laboratory and numerical models have helped to understand plate boundary evolution at the geological time-scale. However many aspects of short-term subduction dynamics remain unclear. The series of thrust megathrust earthquakes of the last 15 years, besides highlighting the social relevance of geodynamic studies, has opened a window into the dynamics of subduction zones at the seismic cycle time-scale. The combination of seismic, geodetic and numerical modeling has helped to understand the physical characteristics of the megathrust earthquakes and the role of the fault geometry, temperature, fluid circulation, petrology and seismic/aseismic energy partitioning to the dynamics convergent margins. We welcome contributions from geodynamicists, seismologists, geodesists and geologists aiming at exploring the relationship between subduction zone dynamics and seismic cycle.
