Underwater geological disaster monitoring system

The utility model discloses a measuring instrument, and especially relates to a device which can be used underwater to monitor the geological disaster. An underwater part of the underwater geological disaster monitoring system includes an earthquake wave detector, a hydrophone, and a magnetometer. The earthquake wave detector, the hydrophone, and the magnetometer are connected with a seabed junction box respectively. The seabed junction box is connected with a system work station via an onshore branch box, wherein the seabed junction box is provided inside with a photoelectric conversion device. An abovewater part includes the system work station, a power supply, and the like. The advantages of the underwater geological disaster monitoring system are that the system can be used on an island, and the operation is convenient, and the data is accurate. The system can monitor and display a seabed signal realtimely. The underwater geological disaster monitoring system can have a wide application in the aspects of the natural disaster monitoring, the ship monitoring, and the like.
