    Abstract

    Submarine landslides can pose a significant threat to offshore infrastructure supporting exploitation of marine resources, and
    catastrophic landslides may generate devastating debris flow and tsunamis. The thesis has focused on initiation and evolution
    of submarine landslides due to shear band propagation in a weak layer combining analytical and numerical work Initiation
    mechanisms and rigorous criteria for progressive and catastrophic shear band propagation have been established for planar
    and curvilinear slopes under static and dynamic conditions, with interpretation allowing simple and practical application. The
    thesis has also discussed conditions for slab failure and post-failure processes during catastrophic shear band propagation.
