Simulation submariner Hangrutschungen an aktiven Kontinentalrändern

Description: Im Rahmen dieses Projektes untersuchen wir die topographische Entwicklung aktiver Kontinentalränder, die durch Prozesse der Hangdestabilisierung gekennzeichnet sind. Wir verwenden hierzu analoge Simulation und ziehen Vergleiche zu natürlichen Systemen.

  Title: Submarine landslides - Simulation of submarine slope collapse at active plate margins
  Description: Giant submarine landslides occur along active plate margins where sediments are scraped of the incoming plate, piled up at the leading edge of the overriding plate and accreted to form the accretionary wedge of a subduction forearc. They pose not only a tsunami hazard but may also have a profound greenhouse impact since submarine landslides could trigger the release of methane stored as hydrate in the slope sediments. Single events may be triggered by nearby earthquakes and pore pressure changes but the long-term slope degradation pattern is likely controlled by the interplay between gravity (driving force) and the strength of the accretionary wedge and its base (resistant force). In this project we study submarine landslides at active plate margins performing physical experiments monitored with a high-resolution image correlation system (particle imaging velocimetry PIV) and elastic dislocation modeling. This hybrid approach honors the nature of the landslide process as being a fracture phenomena controlled by gravity, inertia and friction. We simulate the initiation and evolution of incremental and catastrophic slope collapse above a seismogenic megathrust and analyze the evolving patterns of surface deformation. By this we aim at identifying the potential of mapping the mechanical properties at depth using bathymetric data as well as future ROV and sea-floor GPS techniques. https://ufordat.uba.de/UFORDAT/pages/PublicRedirect.aspx?TYP=PR&DSNR=1015832
