Observations of anelasticity at seismic frequencies can help advance our understanding of the planet across diverse temporal and spatial scales from radial Earth structure to sedimentary and geomorphic processes. Attenuation can help constrain a variety of subsurface properties including temperature, abundance of fluids (melt, water, others), porosity, degree of weathering, lithology, and grain size as well as grain boundary processes. The aim of this session is to bring together scientists working on or utilizing different aspects of seismic attenuation to provide a comprehensive and interdisciplinary overview of recent advances on this topic. We invite contributions that review the latest theoretical, experimental, and observational studies of seismic attenuation at all frequencies—from normal modes to the kHz range—and that explore new insights on Earth processes provided by these results. To capture the broad range of applications, we encourage submissions from every subdiscipline on everything from critical-zone to planetary-scale studies.
