Methods for Site Response Estimation
Date: 4/26/2019
Time: 8:30 AM to 2:45 PM
Room: Pine
Assessing the influence of soil and rock properties on the strength of earthquake ground shaking is an area of active research because of the importance of such “site effects” to realistically quantify potential seismic risk to infrastructure. The hazards community is moving beyond simple measurements of Vs30 (average shear-wave velocity in the upper 30 m) to measuring, modeling and predicting more accurate site response. These approaches include inverting various datasets for shear wave velocities at a range of depths, identifying hard boundaries that influence site response and also developing methods for direct measurement of site response through, such as spectral ratios using earthquake or ambient noise signals. In this session we invite abstracts on innovative methods for site response characterization, data collection approaches needed for such characterizations, as well as case studies showing the application of these methods.
