In 1996, Ocean-bottom geophysical observatory was installed off Sanriku, northt-eastern Japan, for the purposes of studying earthquakes and tsunamis in the Earthquake Prediction Program of Japan. The landward slope region of the northern Japan Trench off Sanriku is characterized by its active seismicity which is directly related to the dynamics of subduction of the Pacific plate. In situ realtime geophysical monitering of earthquake are expected to play an important role in studies for earthquake prediction. These seismometers and two tsunami meters ( pressure gauges ) are placed on the seafloor of its water depth being deeper than 1,000m.
