Early tsunami forecasting using visible-light LEDs for sea-level measurement from the seabed

A sea-level measuring and detection system is proposed for application in the detection of seabed movements to forecast tsunamis. Target implementation objectives include flood control systems and ocean meteorology where LEDs will be installed on sea floors and river beds. Light intensity received is converted to the length of vertical displacement to reflect any rise or fall of the sea floor. Sea level and the amplitude of wave movements can also be measured using this method. The design of such a prototype is discussed.
