Numerical Models, Laboratory Experiments, and Field Observations of Explosive or Earthquake Sources and Seismic Wave Propagation for Nuclear Explosion Monitoring
Session ID#: 252394
Session Description:
Investigations related to how complexities in explosive or earthquake sources (e.g., point sources, finite source geometries, source depth, source energy) and near-source parameters (e.g., topography, material properties, damage) could potentially impact the resultant seismic waves for monitoring are areas of active and challenging research. This session intends to highlight physics-based capabilities of various numerical modeling codes as well as laboratory and field studies in source characterization and resultant seismic wave propagation for monitoring applications. We are open to a wide range of studies related to explosion source dynamics, earthquake rupture dynamics, source geometry/characterization, velocity structure, tectonic prestress, and material properties around sources including plasticity, fracturing, and permanent deformation. We also encourage contributions on novel research that explores scaling between numerical models, laboratory experiments, and field observations applicable to monitoring.
