Exciting news! We're transitioning to the Statewide California Earthquake Center. Our new website is under construction, but we'll continue using this website for SCEC business in the meantime. We're also archiving the Southern Center site to preserve its rich history. A new and improved platform is coming soon!

Fw: Special Sessions of the SSA 2012 Meeting

Date: 12/22/2011

To SCEC Community, Forwarded message from Nico Luco below. Happy holidays, John

I'd like to call your attention to 2 sessions of the 2012 SSA meeting in San Diego (abstract deadline January 11).

Numerical Modeling of Earthquake Motion and Seismic Wave Propagation

Numerical modeling has been and will likely remain an important tool for investigating rupture propagation, earthquake ground motion and seismic wave propagation. Refinements and innovations in numerical modeling are being driven by the demands to interpret increasing volumes of seismic data; the scientific and engineering requirements to reproduce and predict seismic motion in realistically complex media over a broad frequency band; and the rapid development of computer resources. Advancements (e.g., in modeling capabilities, accuracy levels, and computational efficiency) are spurred when there is joint involvement of, and interactions among, mathematical and computational scientists, algorithm developers, and those applying the methods. We invite contributions focused on development, verification and validation of the numerical-modeling methods, and on methodologically important applications. Contributions on the analysis of methods, development of fast algorithms, GPU applications, large-scale simulations, non-linear behavior, multiscale problems, and confrontation of methods with data are especially encouraged.

Validation of Strong Ground Motion Simulations for Engineering Applications

Despite the thousands of strong ground motion records readily available online, there remains a shortage of records for large magnitude earthquakes at short distances, not to mention for other specific source, path, and site characteristics. More and more, physics-based and/or stochastic numerical simulations of strong ground motions are able to offer realistic samples of such records, but the simulation models should first be validated against available strong ground motion data. This special session focuses on efforts to statistically validate simulated records for engineering applications. Such applications include nonlinear response history analysis of geotechnical or structural (e.g.,building, bridge) systems for building code or risk assessments, and development of prediction models for ground motion intensity measures (e.g.,spectral acceleration).
