The invention discloses a piece of equipment for submarine landslide monitoring. The equipment comprises a long rod-shaped sealing housing. A magnetic sensing mechanism is arranged inside the sealing housing. The magnetic sensing mechanism comprises a movable rod and a measuring rod. The upper end of the measuring rod is provided with a hollow chamber. The lower end of the movable rod is clamped inside the hollow chamber in a rotatable way. The hollow chamber bottom is provided with a magnetic sensing chip. The lower end of the movable rod is fixedly provided with a magnetic induction sheet. A power supply module, a control module and a storage module are further arranged inside the sealing housing. The control module comprises a controller, a clock circuit and a relay. The equipment which has relatively good sensing measuring precision performs effective automatic monitoring and recording on multiple bedding planes of a seabed and monitors in a way to switch from a single-point way to a multi-point way to form a stereoscopic monitoring face. Direct-viewing data are provided for submarine landslide researches. Information supports for natural disasters such as landslides, earthquakes, tsunamis, etc. and early warning services thereof are provided. Meanwhile, the equipment which has the characteristics of convenient operation and low cost can be used for underwater monitoring for a relatively long time.
