Advances in Understanding Near-Field Ground Motions: Observation, Prediction and Application

The characterization of near-field ground motions is critical for expanding our understanding of earthquake hazard as well as improving rapid response and earthquake early warning efforts. Recent earthquakes like the 2019 Ridgecrest Sequence have provided observations of near-field ground motions in unprecedented detail, while increased computational capabilities have enabled significant advances in ground-motion simulations. With these developments come new opportunities to improve our understanding of near-field seismic ground motions, including, for example, how ground-motion characteristics translate into perceived shaking intensities as well as characterization of path and site effects. In turn, these improvements in near-field ground-motion models can lead to increased accuracy in applications such as early warning alerts, rapid response loss estimates and structural response to shaking. We invite submissions related to this broad area of near-field ground motion. Possible topics include: near-field observations; advances in near-field ground-motion modeling; and applications such as seismic hazard modeling, structural response modeling, rapid response products and earthquake early warning.
