Topics: IASPEI Meetings
The Joint Scientific Assembly off IAG and IASPEI will be held this year in Kobe, Japan during July 30 - August 4, (2017). I would like to draw your attention to the following sessions being convened for that assembly related to lithospheric structure and deformation.

Please note that the Abstracts deadline is coming up very soon - February 8!

Joint IAG-IASPEI Symposium

J03 Deformation of the lithosphere: Integrating seismology and geodesy through modelling (co-sponsored by the International Lithosphere Program (ILP))
Convener: Kevin P. Furlong (Park University, USA)
Co-convener: Rob Govers (Utrecht University, The Netherlands), Takuya Nishimura (Disaster Prevention Research Institute, Kyoto University, Japan)
The past decade has witnessed significant advances in our capabilities to observe lithospheric deformation on a range of spatial and temporal scales. Improved tools for imaging earthquake rupture processes, and the combination of densified, continuous GPS (cGPS) networks with space-based and airborne direct observations of crustal deformation such as InSAR and LiDAR have led to substantial improvements in our understanding of lithospheric deformational processes. In this symposium we invite submissions reporting research involving the acquisition and analyses of seismologic and geodetic data, and the utilization of those data through modeling to map and quantify rates and patterns of lithospheric deformation. Of particular interest are (1) studies that integrate data sets and data types, (2) modeling of processes that span temporal ranges including the earthquake cycle and subsequent rupture, and (3) longer term processes that permanently deform the lithosphere.

This symposium is co-sponsored by the International Lithosphere Program.

IASPEI Symposia

S21 Lithospheric structure
Convener: Jaroslava Plomerová (Czech Academy of Sciences, Czech Republic)
Co-convener: Shun Karato (Yale University, USA), Juan Carlos Afonso (Macquarie University, Australia), Ulrich Achauer (Institut de Physique du globe de Strasbourg, France), Kevin P. Furlong (Park University, USA)
The aim of this multidisciplinary symposium is to bring together scientists working in the fields of observational and theoretical seismology, electromagnetism, geodynamics, tectonics, mineral physics, experimental petrology, modelling and geochemistry to present their achievements in various studies of the lithosphere-asthenosphere system, to stimulate interdisciplinary discussion and interpretations of the results. Contributions presenting results on
• Scales of the lithosphere and upper mantle heterogeneity and anisotropy. Regional and global studies
• Origin and imaging of the mantle lithosphere discontinuities (Moho, MLD, LAB, etc.)
• Advantages and resolutions of different inversion methods for studying the deep Earth structure
• Models of anisotropic fabrics of the lithosphere-asthenosphere system resulting from ancient and recent processes
• Dynamics of the lithosphere-asthenosphere system from multi-observable probabilistic tomography
• Constraints from textures in xenoliths and exposed mantle sections
• Constraints from laboratory studies
• Constraints from geodetic observations (e.g., post-seismic deformation, slow slip events)
• Mechanical interactions between the lithosphere and asthenosphere
• The role of water in the development of anisotropy
• Relationship between surface tectonics and the underlying mantle flow
• The future of geophysical imaging,
achieved with the use of different technique, are preferably welcome. Special attention will be paid to the lithosphere-asthenosphere boundary (LAB), the most extensive and active plate boundary on the Earth, which remains, particularly beneath continents, relatively cryptic compared to other first-order structural subdivisions of Earth. Determination of the LAB depth and answers on what the LAB means from the structural, rheological and physico-chemical point of view remains highly debated and represents a first-order problem in the geosciences. Only multi-disciplinary and/or transdisciplinary efforts, bringing together various disciplines from the Earth Sciences, can shed light on the above questions and lead to i) a better understanding of the lithosphere-asthenosphere system, ii) unravel what the LAB truly is, iii) how it evolves, iv) how it can be better imaged, and v) what role it has played and still plays in the evolution of our planet.

S22 Lithosphere structure and dynamics: Plate boundary deformation at lithospheric scale (co-sponsored by the International Lithosphere Program (ILP))
Convener: Kevin P. Furlong (Park University, USA)
Co-convener: Rob Govers (Utrecht University, The Netherlands)
The goal of this symposium is to bring together scientists who are observing and modeling plate deformation, with an emphasis on plate boundary processes. We are interested in both modern (e.g. GPS, InSAR, Seismologic, etc.) rates and patterns of plate boundary deformation and also the geologic record of past deformation in and near plate boundaries, including paleoseismic studies. Topics of interest include (but are not limited to): partitioning of deformation along plate boundaries, permanent versus ephemeral deformation, near-surface versus deeper rates and patterns of deformation, role of rheology in localizing/diffusing plate boundary deformation, and related topics. We welcome contributions from all styles of plate boundary deformation, i.e. subduction, rifting, and translational.
