The Indian Ocean Warning System has been developed on the likes of the already existing Pacific Tsunami Warning Centre which helps to track tsunamis on the western parts of the globe and consists of a variety of devices to aid the process. Pressure Recorders and Tide Gauges are two of the main gadgets that are used to detect a tsunami attack. These two devices have become quite popular after the aforementioned calamity as seismic devices, which were used initially but sparingly failed to give a sure-shot indication of the calamity. The Indian Ocean Tsunami Warning System is the latest pioneer that has been achieved to alert coastal residents about an impending tsunami.

These two devices have become quite popular after the aforementioned calamity as seismic devices, which were used initially but sparingly failed to give a sure-shot indication of the calamity. Deep-Ocean Assessment and Reporting of Tsunami (DART) is an example of one of the former gadgets mentioned. The device uses buoys and sensors located at deep sea to warn about the attack of a tsunami. A pressure recorder located at the sea bed measures the variance in the weight of the water and sends the data to the buoy located at the water-surface. This received data is added to the surface conditions monitored and tracked by the buoy and sent via a satellite signal to a receiving station. The biggest advantage of installing a pressure recorder like the DART is that it is accurate and gives ample time as regards warning the people concerned is taken into consideration. The biggest disadvantage is that it is quite expensive and often governments might forgo this technology on account of the expenditure more than anything else.
