The STB system consists of three subsystems: a surface communications buoy, a buoy mooring, and a bottom pressure recorder. The bottom pressure recorder includes a highly accurate sea floor pressure sensor which can detect earthquakes and sea level changes. Acoustic communications transmits the bottom sensed pressure data to the surface buoy which then relays the data by satellite communications to the Tsunami Warning Center for analysis. Once processed, the data can provide real-time assessments of whether or not a tsunami has formed due to seismic events or other forcing such as an underwater mudslide.
"Once deployed, the STB will be a key sensor in providing early assessment of possible destructive tsunamis in one of the most seismically active regions of the world," said Tom Baybrook, SAIC senior vice president and business unit general manager. "We look forward to continuing to deliver reliable and technologically sound tsunami assessment systems to support a global integrated tsunami warning network."
