Dear colleagues,

We would like to draw your attention to our AGU Fall Meeting 2019 session, T026 - Integrating Plate Interface Rheology and Seismicity with Subduction Zone Geodynamics. The interdisciplinary session aims to explore the interplay between rheological dynamics at the shear/fault zone scale and large scale subduction geodynamics, with a focus on the implications for seismicity.

Invited Presenters:
Paola Vannucchi (Royal Holloway, Univ. of London)
Sylvain Barbot (USC)

Adam Beall (Cardiff Univ.), Whitney Behr (ETH), Luca Dal Zilio (Caltech) and Yajing Liu (McGill Univ.).

The rheological and frictional properties of the plate interface determine the degree of interseismic locking, seismic rupture size and the geodynamic coupling that influences long-term crustal deformation and possibly plate velocities. In turn, the interface rheology is influenced by petrology, stress state, temperature, fluid pressure and sediment thickness, which are all controlled by the broader geodynamics. A holistic understanding requires integrated studies of spatial scales ranging from fault/shear zones to tectonic plates and temporal scales from seconds to million-years. We welcome contributions from all relevant disciplines that use observations or models to explore the relationships between fault/shear zone rheology, megathrust seismicity and broad-scale geodynamics.

We look forward to seeing you in San Francisco,
Adam, Whitney, Luca and Yajing
