The North Irian Basin is located at the convergence and compression edges of the Australian and Pacific plates. Since the Late Cretaceous, the Australian Plate has been moving northward, and collision with the Pacific Plate has occurred several times, forming a complex area of tectonic activity. This provides a foundation for the formation of extensive landslides on the seafloor in the northern margin of the basin. By analyzing the high precision 2D seismic data in the north of the basin, the characteristics of submarine landslides are described in detail. Three structural units of a submarine landslide, namely the headwall domain, translation domain, and toe domain, are identified, which have their typical seismic characteristics. Submarine landslides are widespread in this area and can be divided into four types: continental slope/shelf, channel wall, valley, and Mass Transport Deposits (MTDs). Combined with the regional geological background of the basin, it is considered that the tectonic movement of subduction and collision between plates plays a major role in controlling submarine landslides, which is induced by the combined action of external factors such as the submarine terrain slope as the internal cause, the sediment supply rate, sea-level change, and seismic activity.
