Subaqueous Evidence for Earthquakes, Coseismic Landslides, Tsunamis and other Cascading Hazards
Large earthquakes, tsunamis and landslides can have major impacts on populations, infrastructure and habitats across local, regional and transoceanic scales. The destructive impact of these events can be compounded through associated triggering (e.g., shaking induced landsliding and tsunami genesis). Subaqueous environments (i.e., marine and lacustrine) can provide stratigraphic records and quantitative insights to reconstruct these catastrophic events across a range of temporal and spatial scales. High-resolution geophysical imagery combined with detailed geological sampling and geochemical analyses can provide critical context around preconditioning factors as well as the environmental response to these geohazards. We encourage submissions that integrate onshore and offshore geological, geophysical, geochronological and/or geotechnical datasets along active or passive margins to provide constraints on geohazard characterization and/or link fundamental geological processes to geohazards. In addition, we welcome submissions that combine physics-based modeling and geological or geophysical observations from marine, coastal and lacustrine environments to understand and anticipate geohazards.
