Dear Colleagues,

We would like to encourage you to consider submitting an abstract to session T222: Decadal to millennial strain accumulation at subduction zones, at the Geological Society of America fall meeting in Seattle Washington, October 22-25, 2017. The goal of this session is to bring together researchers from various sub-disciplines to discuss advances in understanding and quantifying the spatio-temporal evolution and mechanics of strain accumulation at subduction zones over a range of timescales.

We have confirmed talks by Kelin Wang, Univ. of Victoria/ Geol. Survey of Canada, and Patricia McCrory, USGS.


T222 Session Description: Quantifying the relative contributions of recoverable and permanent strain in subduction systems is critical to understanding the geodynamic processes that drive the growth and evolution of topography, and the feedbacks between subduction zone convergence and upper plate deformation. Geodetic and seismic networks capture a record of decadal-scale strain accumulation, and multidisciplinary studies based on paleoseismology and high-resolution topography and bathymetry document how millennial-scale permanent strain is accommodated on active (Holocene) structures. However, the relationships between decadal displacements from GNSS and seismicity data and permanent deformation along crustal faults remain unclear. We invite submissions that quantify strain accumulation in Cascadia and at other subduction zones over timescales that span seconds to millennia in either onshore or offshore settings, particularly those that integrate deformation across spatial and temporal scales.


The abstract deadline is August 1. More information about the meeting and abstract submission can be found here: http://community.geosociety.org/gsa2017/home;


We hope to see you in Seattle!


Regards,

Christin Regalla, Kristin Morell, Colin Amos, Scott Bennett, Lucinda Leonard, and Jack Loveless
