A Framework for Online Inversion-Based 3D Site Characterization
Our goal is to develop the capability for characterizing the three-dimensional geological structure and mechanical properties of individual sites and complete basins in earthquake-prone regions. Toward this end we present a framework that integrates in situ field testing, observations of earthquake ground motion, and inversion-based modeling. 1 Geotechnical Site Characterization An important first step for forecasting strong ground motion during future earthquakes in seismically-active regions is to characterize the three-dimensional mechanical properties and geological structure of sites and basins within those regions. Characterizing a site refers to our ability to reconstruct as faithfully as possible the soil profile in terms of a limited set of material parameters, such as shear and compressional wave velocities, density, attenuation, and the slow velocity for poroelastic media. Geological and geotechnical materials, soil and rock, impact the performance of the built environmen...
