The CIG Webinar Series draws from a pool of experts from mathematicians, to computer scientists, and to geoscientists, among others to bring together a cross-cutting community of faculty, students and researchers to both inform and disseminate knowledge on the tools and methodologies employed to further the study of problems in geodynamics.
The one hour webinars will be held the 2nd Thursday of each month October through May. Webinars will be recorded for later viewing. Reminders and details will be sent out through the cig-all mailing list.

The Release of the GEM Global Active Faults Database and Global Seismic Hazard Map
Richard Styron, GEM Foundation
In late 2018, the Global Earthquake Model Foundation (GEM) released the initial version of several major products relating to seismic hazard and risk, including the Global Seismic Hazard Map, the Global Seismic Risk Map, and the Global Active Faults Database. Though these are intended primarily to support GEM's mission to reduce earthquake risk, they may be of use or interest to geodynamics researchers and the broader Earth science community. The GEM Global Active Faults Database (github.com/GEMScienceTools/gem-global-active-faults) is a dynamic, evolving compilation of active faults worldwide, currently containing ~14,000 fault traces. Associated metadata describe the geometry, kinematics, slip rates and other parameters relevant to seismic hazard analysis. Metadata completeness varies regionally, with ~75% of faults having some slip rate information. The GEM Global Seismic Hazard Map (globalquakemodel.org/gem) displays the geographic distribution of Peak Ground Acceleration with a 10% probability of exceedance in 50 years, and is derived from a mosaic of national or regional seismic hazard models created by a variety of organizations including the GEM Secretariat. Additional topics of collaboration or mutual beneficial research between the geodynamics and seismic hazard communities will be discussed. [pdf]
Seismic data and data products to motivate, guide, and test geodynamic models of the lithosphere and upper mantle
Brandon Schmandt, University of New Mexico
Observational seismic data and data products are among the major sources of information about structure and multi-scale deformation in the lithosphere and underlying mantle. However, the data and products come in many forms that continue to evolve and the observational perspective is inherently messy. Physical modeling frameworks take a process-based perspective that can yield one or more viable explanations for the major features identified by observational seismology. Such interactions between seismology and geodynamics have been highly fruitful over the past few decades. The purpose of this webinar is to consider relatively new observational seismology products or methods of access that might facilitate advances on outstanding questions about tectonic and magmatic processes. Crust and upper mantle (an)isotropic tomography, imaging of sharp interfaces, and earthquake catalogs will be emphasized as observational constraints. Many of the outstanding questions emphasized will be related to deformation involving fluid-solid coupling or spanning multiple rheological regimes.
