DSB Seminar: Probabilistic Inversion in Marine Geoacoustics and Earthquake Seismology
Stan Dosso, School of Earth and Ocean Sciences, University of Victoria, Victoria BC Canada
Estimating geophysical properties from seismo-acoustic waves is an important problem in both marine and terrestrial environments. Knowledge of seabed properties, including shear parameters, is important for sonar, geophysical and geotechnical applications and slope stability studies. On land, estimating the shear-wave velocity over the upper 10s of metres defines the expected amplification in earthquake shaking, while estimates over 10s of kilometres depth images geologic and tectonic structure. In all cases, a probabilistic (Bayesian) approach to acoustic/seismic inversion provides rigorous, quantitative uncertainty analysis for results.
