Full-Waveform Modeling and Inversion: Advances and Applications Posters


Submit an Abstract to this Session


Session ID#: 51866

Session Description:
Full-waveform numerical modeling methods accurately simulate complex wave propagation in 3D Earth media, accounting for heterogeneity, anisotropy, attenuation, and interfaces. These methods have led to great progress in imaging Earth’s structures and in studies of seismic sources. We focus on recent developments in full-waveform-based methods and applications, including but not limited to: (1) forward modeling and inversion algorithms, (2) automatic data processing such as artificial-intelligence-based methods, (3) multi-scale imaging of wavespeed, anisotropy, density, and attenuation structures using earthquake, ambient noise, and active-source data, (4) inversion of earthquake source locations, moment tensors, and earthquake rupture processes, (5) model evaluation and validation, (6) full-waveform reverse time migration, and (7) wave-prediction and observation of site amplification and surface ground-motion related to seismic hazard assessment. We strongly encourage abstracts that highlight new geological/tectonic insights resulted from full-waveform approaches, or from joint approachs combining seismic methods with other geophysical methods (e.g., gravity and magnetotelluric analysis).
