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.
