The Tsunami waves cause considerable destruction and kills people . The detection section of the proposed system consists of a microcontroller, a vibration sensor to detect the Tsunami occurrence and a tilt sensor to monitor the sea waves. The principle is as follows, on the onslaught of Tsunami or any other natural calamity of this type , there is an abnormal pressure changes in the sea floor producing vibrations. Here a piezoelectric vibration sensor is used which gives an output depending on variations, and a microcontroller is used to announce the oncoming of Tsunami event to a concerned person, through the mobile computing. Mobile is used to give warning calls or send warning messages.
