The Japan Meteorological Agency in Tokyo has granted Science Applications International Corp. a contract for six tsunami buoy systems, SAIC announced today.
Under the terms of agreement, SAIC will manufacture STM systems which will be incorporated into the agency’s existing sensor network to provide critical assessment data of tsunami’s generated in the oceans east of Japan.
In an effort to enhance its current warning system and provide direct assessment capability of tsunami waves, JMA intends to deploy the systems across the northwest Pacific Ocean located 200 nautical miles east of Sendai, Japan.
Thomas Watson, SAIC SVP and business unit general manager, said through the STB technology, SAIC will help enhance Japan’s warning system in response to the tsunami tragedy in 2011.
The STB system uses a sea floor pressure sensor to detect earthquakes and sea level changes with acoustic communications to transmit pressure data to the surface buoy.
SAIC said the surface buoy transfers data to forecast centers for analysis through satellite communications in order to provide real-time assessments of the tsunami in deep water.
The processed data will then be used with forecast models to predict the amplitude of the wave and inundation once it reaches a coastal location.
According to a statement from JMA, the deployment of the buoys will help detect tsunamis generated around the Japan Trench axis off the Tohoku region for about ten minutes following an earthquake and deliver information on offshore tsunami observations to assist in tsunami evacuation activities.
