Session Description:
Marine geohazards are sudden and extreme geologic events that affect coastal areas and seabed infrastructure on local, regional and transoceanic scales. The hazards include submarine earthquakes, submarine landslides, explosive volcanic eruptions, and tsunami generation. For example, recent advances in marine paleoseismology have provided critical constraints on potential magnitude and timing major offshore earthquakes. We seek a broad range of contributions that highlight new results and methodologies in subaqueous environments, particularly those that apply high-resolution geophysical imaging, geochronology (i.e., recurrence intervals), and modeling techniques to evaluate geohazards. We also emphasize studies that span major geomorphic process domains (e.g., the shoreline and the shelf-edge) of both active and passive continental margins, studies that examine linkages between two or more hazard types, and studies that present new data from poorly characterized regions.
