Multi-disciplinary investigation into the role of regional event beds in near-shore landslides
Multi-disciplinary investigation into the role of regional event beds in near-shore landslides
Shallow-water submarine landslides are a widely observed landform, seen in fjords, lakes and rivers at all latitudes. With run outs of several km and the ability to both retrogress inshore as well as generate potentially hazardous tsunamis, they represent a significant hazard to offshore and near-shore infrastructure. However, their complex architecture and sensitivity to subtle changes in the mechanical properties of soils makes them extremely difficult to study, requiring a comprehensive combined assessment of the structural and soil mechanical architecture of the slope and subsurface. Here we present a highly detailed, integrated geophysical, geological and geotechnical study of the parameters controlling submarine slope stability in a fjord in northern Norway.

Abstract
Shallow-water submarine landslides are a widely observed landform, seen in fjords, lakes and rivers at all latitudes. With run outs of several km and the ability to both retrogress inshore as well as generate potentially hazardous tsunamis, they represent a significant hazard to offshore and near-shore infrastructure. However, their complex architecture and sensitivity to subtle changes in the mechanical properties of soils makes them extremely difficult to study, requiring a comprehensive combined assessment of the structural and soil mechanical architecture of the slope and subsurface. Here we present a highly detailed, integrated geophysical, geological and geotechnical study of the parameters controlling submarine slope stability in a fjord in northern Norway.
