Embodiments provide a method for geomagnetically detecting a submarine cable, including: performing a preliminary detection by controlling an underwater robot equipped with a proton magnetometer; determining a preliminary direction and location of the cable based on preliminary detection information; controlling the underwater robot equipped with the proton magnetometer and two fluxgate magnetometers to launch into the water; controlling the underwater robot to travel over the cable and determining specific location information of the cable; controlling a heading of the underwater robot to move along the preliminary direction of the cable; and controlling the underwater robot equipped with the proton magnetometer and the two fluxgate magnetometers to launch into the water; determining whether a fault in the submarine cable occurs and a location of a fault point, based on Z-axis components of the general geomagnetic field and launching depth data of the underwater robot.
