Problems solved by technology

Due to the complexity of the submarine environment, the process of submarine landslides may be slow and subtle. At present, there is no effective way to monitor submarine landslides. The current fixed-point investigation and recording after the event requires a large workload, high cost, and is not necessary. Real-time and long-term observation

Description

technical field [0001] The invention relates to the field of seabed monitoring, in particular to a device for monitoring seabed landslides. Background technique [0002] Submarine landslides usually refer to unconsolidated soft sediments on the seabed or rocks with weak structural planes, which rapidly slide along the slope under the action of gravity, including translational landslides and rotational landslides; in a generalized sense, submarine landslides generally cover the movement of seabed sediments. Various processes, including peristalsis, collapse and gravity flow (debris flow, particle flow, liquefaction flow, turbidity flow) phenomenon. Generally speaking, submarine landslides are complexes of landslides of different types and periods. Moreover, during the handling process, its structural characteristics and mechanical properties are time-varying, accompanied by type changes. [0003] Submarine landslides are a type of marine disaster. The reasons for submarine...
