Abstract: Our environment currently suffering from multiple issues due to change in nature like global warming, natural disasters like Tsunami, earthquake, floods, volcanic eruptions, etc. To predict before disaster is challenging task where scientist invent devices to get simultaneous data regarding environment changes with the help of sensors. In the study, we designed a device which senses waves in seas that manipulates via Tsunami buoys. Tsunami buoys are deployed in deep seas and high wave regions to get various surrounding data that helps to predict Tsunami. National geographic centers have the facility to collect the data from various Tsunami buoys, each data is been analyzed, manipulated, systemized into a centralized prediction mechanism. Electromagnetic wave sensors embedded in each Tsunami buoys that plot courses among others to simulate variation on waves. According to that Wide Range Angle Calculation (WRAC) methodology, arc kind of diplomatic solution is implemented to check and calculate the wave radius which is later then derived, predicting damage circles. By this device, circle radius of damage is identified and avoiding the damage percentage before it started to destroy surroundings as well as human beings.
