The source is finite-fault model produced by USGS National Earthquake Information Center containing 14 subsources. The 3D structural model is a tomographic model from Eberhart-Phillips et al. (2016), plus embedded sedimentary basins of Cook Inlet, Susitna, and Peters Hill. Topography and bathymetry are modeled as well. The simulation is performed on a mesh of 4.7 million hexahedral elements. The simulation used the CIG code SPECFEM3D, run on 280 cores of the chinook cluster at University of Alaska Fairbanks. Technical notes of the simulations can be found on youtube (https://youtu.be/SsR_fRDIQXk ). Courtesy of Carl Tape -------------- next part -------------- An HTML attachment was scrubbed...

The abstract submission deadline is approaching (10 January 2019). For those interested in the application and the development of numerical models for the study of geological processes, feel free to join: Advances in Numerical Modelling of Geological Processes Session details can be find below.

May ----------------------------------------------------------------------------------------------------------- Advances in Numerical Modelling of Geological Processes [GD8.1/EMRP1.81/SM7.6/TS11.6] Geological and geophysical data provide quantitative information which permit the advancement of our understanding of the present, and past, interior of the Earth. Examples of such processes span from the internal structure of the Earth, plate kinematics, composition of geomaterials, estimation of physical conditions and dating of key geological events, thermal state of the Earth to more shallow processes such as reservoir geomechanics, or nuclear waste storage. A quantitative understanding of the dynamics and the feedbacks between geological processes requires the integration of geological data with process oriented numerical models. Innovative inverse methods, linking forward dynamic models with observables, are topics of growing interest within the community. Improving our knowledge of the governing physical parameters can thus be addressed while reconciling models and observables. Resolving the interactions between various processes occurring at scales differing from each other over several orders of magnitude in space and time represents a computational challenge. Hence, simulating such coupled, nonlinear physics-based forward models requires both the development of new approaches and the enhancement of established numerical schemes. The majority of geological processes combine several physical mechanisms such as hydrological, thermal, chemical and mechanical processes (e.g. thermo-mechanical convection). Understanding the tight couplings among those processes represents a challenging and essential research direction. The development of novel numerical modelling approaches, which resolve multi-physics feedbacks, is vital in order to provide accurate predictions and gain deeper understanding of geological processes. We invite contributions from the following two complementary themes: #1 Computational advances associated with - alternative spatial and/or temporal discretisations for existing forward/inverse models - scalable HPC implementations of new and existing methodologies (GPUs / multi-core) - solver and preconditioner developments - code and methodology comparisons (“benchmarks”) - open source implementations for the community #2 Physics advances associated with - development of partial differential equations to describe geological processes - inverse and adjoint-based methods - numerical model validation through comparison with natural observations and geophysical data - scientific insights enabled by 2D and 3D modelling - utilisation of coupled models to address nonlinear interactions -------------- next part -------------- An HTML attachment was scrubbed...

Kind regards, Ria Fischer Peter A. Cawood Nicholas Gardiner Antoine Rozel Jeroen van Hunen *Session GD1.2/AS4.61/BG5.4/CL1.01/GMPV1.6/TS1.6** **"Early Earth: Dynamics, Geology, Chemistry and Life in the Archean Earth"** *Processes responsible for formation and development of the early Earth (> 2500Ma) are not well understood and strongly debated, reflecting in part the poorly preserved, altered, and incomplete nature of the geological record from this time. In this session we encourage the presentation of new approaches and models for the development of Earth's early crust and mantle and their methods of interaction. We encourage contributions from the study of the preserved rock archive as well as geodynamic models of crustal and mantle dynamics so as to better understand the genesis and evolution of continental crust and the stabilization of cratons. We invite abstracts from a large range of disciplines including geodynamics, geology, geochemistry, and petrology but also studies of early atmosphere, biosphere and early life relevant to this period of Earth history. -- ------------------------------------------------------------------------ *Dr. Ria Fischer* Seafloor Modelling Group GEOMAR Helmholtz Centre for Ocean Research Kiel ------------------------------------------------------------------------ Wischhofstr. 1-3, Geb. 12 24148 Kiel, Germany T +49 431 600 2843 rfischer at geomar.de ------------------------------------------------------------------------ -------------- next part -------------- An HTML attachment was scrubbed...
