MG14A:
Marine Geohazards I Posters

Session ID#: 84879

Session Description:
Marine geohazards are sudden events that occur offshore or along the coast, with impacts ranging from local-scale to across ocean basins. Commonly occurring geohazards include earthquakes, underwater mass wasting events, tsunami generation and inundation, extreme flooding events, and explosive volcanism. These geologic processes can potentially influence marine habitats, urban centers, and offshore infrastructure, as they bridge multiple environments from terrestrial through the deep sea. As marine systems typically preserve sedimentary signals better than the terrestrial environment, previous events are more likely to be captured in the offshore record and are ideal for investigating hazards posed to population centers. We invite submissions from marine or coastal environments that investigate past hazards using stratigraphy, geophysics, or geochemical proxies. Additionally, we welcome submissions that observe presently active systems and model future hazards, working towards a better understanding of the spatial and temporal scales of marine geohazards.
