Catching an earthquake and closing the gate automatically to stop Tsunami

Most of the conventional landlocks and water gates are opened and closed by manual or electric operation on site or by remote control. Now the system has been developed that does not require a person's manual or remote operation to cope with such an incident, in consideration of safety of local residents at Tsunami etc. when an earthquake occurs. This is a combination of driving and earthquake-sensing devices that closes down the water gate automatically without electric power supply, linked with shaking itself of an earthquake. The landlock gate is automatically closed at the earthquake of a seismic intensity of 5 upper.
