Outline of Final Research Achievements

This study aims to make use of real-time data being sent from the ocean-bottom pressure sensors for effective tsunami forecasting. For this purpose, two major scopes are conducted in this study; one is to design digital filter to be applied to the real-time data acquired near tsunami source area, and one is to interpret the in-situ pressure data to enhance tsunami detectability. Applying the designed filter to the pressure data at the 2003 Tokachi-oki earthquake, it is validated that the tsunami signals could be extracted within approximately 1 min. Also, processing and analysis of pressure data acquired by DONET during the 2011 Tohoku earthquake show that the pressure disturbances during the earthquake are involved by the seismic and acoustic waves.
