This conference will provide a unique opportunity to explore the breadth of scientific disciplines relating to rock deformation, including rock physics, geology, geophysics, seismology, mechanics, and civil engineering. The conference will bring together a collection of junior and senior investigators who are at the forefront of their field, and will provide opportunities for junior scientists and graduate students to present their work in poster format and exchange ideas with leaders in the field. The collegial and open atmosphere of this Conference, with programmed discussion sessions as well as opportunities for informal gatherings in the afternoons, evenings and during the meals, provides a venue for scientists from different disciplines to brainstorm and promotes cross-disciplinary collaborations in the various research areas represented. There will be an associated Gordon Research Seminar for early career investigators, before the Conference, August 18-19, 2018. We expect there to be some funds to help support student travel and registration fees. See the two weblinks for both events, from which you can also apply (separate applications are required for each event): Gordon Research Conference on Rock Deformation https://www.grc.org/rock-deformation-conference/2018/ Gordon Research Seminar on Rock Deformation (for early career investigators) https://www.grc.org/rock-deformation-grs-conference/2018/ Attendance is limited for both conferences, so early registrations are encouraged!

Awaji Island is a charming island located 40 km southwest of Kobe. The ACES (ACES ) (APEC Cooperation for Earthquake Simulation) is a multi-lateral grand challenge science research cooperation of APEC. The project is supported by Australia, China, Japan, and USA (core members) as well as Canada, Chinese Taipei, New Zealand, and South Korea (members). It involves leading international earthquake science research groups. ACES aims to develop realistic simulation models, thus providing a "virtual laboratory" to probe earthquake behavior and to access its potential hazards. This capability will offer a new opportunity to gain an improved understanding of the earthquake process and related phenomena, and of earthquake science in general. In this workshop we will focus on the earthquake physics including strain accumulation, earthquake nucleation and propagation, and redistribution of stress and healing. The workshop generally consists of eight plenary scientific sessions as follows. Session 1: Stress accumulation and earthquake preparation Session 2: Earthquake nucleation process Session 3: Earthquake dynamic rupture Session 4: Seismic wave propagation and tsunamis Session 5: Static deformation, stress redistribution and viscoelastic relaxation Session 6: Aftershocks and seismic activity Session 7: Earthquake cycles Workshop Website: http://quaketm.bosai.go.jp/~shiqing/ACES2018/index_aces.html Abstracts Submission and Registration: Opens April 18 Travel Support: We anticipate limited travel support will be available for US participants.

Please review travel instructions on the CIG website before applying. Travel Support Deadline: March 31 ************************************************************************************************* CIG SESSIONS CIG_01: Mantle Convection: Computational Infrastructure for Geodynamics Mantle convection is the process that drives plate tectonics and continental drift on the Earth. It determines the cooling rate of the planet and therefore the core, thus also determining the conditions critical for the geodynamo. Convection in the mantles of other terrestrial planets and both rocky and icy satellites, similarly determines the evolution of these bodies and expressions of their histories such as resurfacing, manifestations of past and present dynamos and volcanism. Progress in understanding these processes on the Earth and other bodies is being driven by continual advancements in computational geodynamic modelling as well as new means of dealing with voluminous model output and tools for visualizing calculation results. This session seeks proposals describing the findings from the full spectrum of studies of mantle convection, new numerical techniques for dealing with issues related to the modelling of mantle dynamics and new tools for dealing with model interpretation. Relevant contributions extend to applications to any system in which convection in a silicate or icy layer is modelled. CIG_03: Lithosphere Dynamics: Computational Infrastructure for Geodynamics As the rigid outer shell of the Earth and the upper boundary layer of the mantle convective system, the lithosphere plays a fundamental role in the Earth’s evolution. However, computational modellng of lithosphere dynamics remains a challenge, as models must encompass wide temporal-spatial scales and incorporate materials with complex, heterogeneous and often poorly constrained properties. Further, recent work highlights the importance of multi-physics processes (e.g., fluid-solid interactions) that are still not fully understood. This session seeks contributions on all aspects of lithosphere dynamics, including studies of specific tectonic areas and those that address computational advances in lithosphere modeling. We also welcome studies that bridge numerical models and observational data and those that link lithosphere dynamics with other parts of the Earth system (e.g., Earth’s surface, convecting mantle). CIG_04: New Developments in Geodynamic Modeling and Computational Infrastructure **** JUST ADDED Advances in numerical modeling capabilities and the influx of big data have widened the scope and scale of geodynamic modeling in the modern era. This session focuses on new developments facilitating modeling of Earth and planetary dynamics. These include generating scientific workflows, data assimilation, numerical methods, leveraging scientific libraries for reproducible research, advances in 3D data visualization, and incorporating new technologies in high performance computing infrastructure. Applications to all aspects of geodynamics are welcome from whole Earth mantle convection, geodynamo studies, short- and long-term tectonics, and as well as the seismic cycle and seismically imaged Earth structure. CIG_02: An Introduction to Modeling Lithospheric Dynamics - TUTORIAL This session will provide a tutorial and training for modeling mantle convection and lithospheric deformation using the state-of-the-art, CIG-supported code ASPECT. The half-day session will begin with a general overview of relevant numerical methods and best practices for modeling complex, non-linear solid Earth deformation. After the introduction, participants will complete hands-on exercises that examine realistic geophysical problems including mantle convection, subduction and lithospheric extension. The session will conclude with a discussion of the exercises and questions regarding developing future numerical studies. Participants are encouraged to come prepared with ideas and hypothesis potentially suited for numerical investigations. No prior modeling experience is required and all interested student, faculty, professional research and industry attendees are encouraged to apply. -------------- next part -------------- An HTML attachment was scrubbed...

Eric Mittelstaedt Message-ID: <41904730-EE87-4B6F-8FAA-AB3464043EB4@ucdavis.edu> THURSDAY, MARCH 8 @2PM PT Where have all the dimensions gone? Hands on methods for introducing students to non-dimensional numbers in laboratory and numerical modeling Eric Mittelstaedt, University of Idaho Experienced modelers are familiar with how non-dimensionalizing mathematical systems can help improve numerical stability, reduce the number of free variables needed to explain a physical system, capture the essential driving processes of a problem of interest, and scale laboratory experiments to the Earth. However, when first introduced to non-dimensional numbers, students often have difficulty understanding how the mantle can have a depth of 1, or how numbers such as the Nusselt number or the Rayleigh number are derived. In this webinar, I will discuss a hands-on, in-class experiment involving a simple oscillator (mass on a spring) that I have used to introduce students to non-dimensionalizing equations, deriving non-dimensional numbers, and scaling experimental results. The mass-spring system is familiar to many students from their introductory physics classes and the mathematical system is simpler than many problems of interest in geodynamics. The combination of familiarity, basic mathematics, and a hands-on experiment facilitate student comprehension and future application of non-dimensional numbers. These methods are aimed at an introductory graduate course or senior level undergraduate course on modeling.
