New Frontiers in Seismic Observations and Modeling with Innovative Methods and Emerging Data on Earth and Other Planets
Seismology is rapidly evolving due to vast amounts of data from classical and emerging instrumentation, as well as advances in theory and computation. The new observational tools include distributed acoustic sensing (DAS), dense nodal arrays, satellites and the ubiquitous cell phones, as well as ocean-bottom/underwater sensors and seismic packages deployed on planetary missions, which complement traditional seismometers. We can now both capture ephemeral surface observations and record wavefields with unprecedented spatial and temporal richness across Earth and other planetary bodies. At the same time, high-performance computing and scientific machine learning enable us to simulate, interpret and invert complex wave phenomena. This session aims to connect these developments by bringing together researchers working on forward and inverse modeling of seismic sources and multi-scale structures, physical interpretation of seismic observations, including unconventional or multi-modal records associated with strong ground motion and human-reported or engineered-environment observations in the near field.
