Deep-ocean channel-wall collapse order of magnitude larger than any other documented
Abstract Submarine channels are the largest conveyors of sediment on Earth, yet little is known about their stability in the deep-ocean.Here, 3D seismic data from the deep-ocean Hikurangi channel-levee system, offshore New Zealand, reveal the largest channel-wall failure yet documented.Collapse of both channel-walls along a 68 km stretch created a
