Modeling and Understanding of High-Frequency Ground Motion [Poster]
Date: 4/24/2019
Room: Grand Ballroom
Seismic wave attenuation is an important topic for both seismology and engineering, as it enters in the prediction of ground motions, site response analyses and the assessment of seismic hazards. In this session, we would like to bring in studies focusing on high-frequency ground motion and its attenuation, as this may have significant impact on the site response and engineering design. As physics-based broadband simulations can reach unprecedented high frequencies, such studies can be of help in understanding ground motion at high frequencies crucial to the seismic response of certain structures, especially for critical facilities.
This session aims at collecting contributions as to how physics-based and empirical modeling handle high-frequency ground motion. We welcome simulation studies that may shed light on the nature of high-frequency attenuation of ground motion, in particular considering also a proper statistical treatment of the uncertainties associated with data collected in the field, the laboratory and through analysis of ground motion records. Topics of interest include crustal attenuation studies, fmax, kappa, spectral analysis studies (stress drop and Q), potential trade-offs between kappa and source, path and site effects, rock and site characterization studies, as well as contributions on the quantification and interpretation of scattering and intrinsic attenuation. Further contributions that help quantify uncertainties in high-frequency attenuation and corresponding ground motion models are also particularly welcome.
