By logging changes in seafloor temperature and pressure, and transmitting the data via a surface buoy to a ground station by satellite, DART enables instant, accurate tsunami forecasts. In Standard Mode, the system logs the data at minute intervals, and in Event Mode, every 15 seconds. A 2-way communication system allows the ground station to switch DART into Event Mode whenever detailed reports are needed. Each DART station consists of a surface buoy and a seafloor bottom pressure recording BPR package that detects water pressure changes caused by tsunamis. The Iridium commercial satellite phone network is used for communication with 31 of the buoys. When on-board software identifies a possible tsunami, the station leaves standard mode and begins transmitting in event mode.

A tsunami is a series of waves that can move on shore rapidly, but last for several hours and flood coastal communities with little warning. Tsunamis can be triggered by a variety of geological processes such as earthquakes, landslides, volcanic eruptions, or meteorite impacts. The threat of a potentially catastrophic tsunami on U. In the wake of the catastrophic Indian Ocean tsunami, which caused more than , deaths and widespread destruction, Congress passed two laws intended to increase efforts to diminish the potential impact of a tsunami. The first P.

This activity has received positive reviews in a peer review process involving five review categories. The five categories included in the process are. Students are required to map the wave front after 5, 10, and 15 hours to better understand the speed and propagation of the tsunami wave.

Each ICG meets regularly to coordinate international tsunami threat services and other mitigation activities. Each center is a backup to the other. Since , the ITIC mission has included the maintenance of a library collection for tsunami research. Through the generosity of many, including public officials and researchers, the library has grown to its present size of approximately items. Materials are in several languages and include an array of types of material, both scholarly, government and popular. Click image above to download as PDF to zoom in.
