Earthquake Ground Motion Simulation (Rupture Dynamics and Seismic Wave Propagation): Theory, Validation and Application.
Session ID#: 78152
Session Description:
Continuous development of numerical modeling methodology in seismology is driving us towards better understanding earthquake phenomena and seismic hazards in a broad span of source, path and site. In areas of infrequent seismicity or 3D complicated geological structure, earthquake ground motions provide accessible approaches to improving the prediction of ground motions for mitigating seismic hazards.
In this session, we invite contributions focused on development, verification and validation of numerical ground motion simulations based on dynamic rupture and seismic wave propagations, and their applications (from previously occurred earthquakes to potential seismic hazard at a specific site). Examples may include but not limit to: 1) macro- and microscopical fault geometry, 2) plasticity adjacent to faults or sites, 3) rupture dynamics on branched or segmented faults, 4) intrinsic and scattering attenuation, and 5) ground surface topography. We also encourage contributions on the analysis of relevant methods, fast algorithms, high-performance implementations and large-scale simulations.
