Consideration about the structure around the senoumi Bank in the Suruga Trough from seismic activity using OBS

Abstract Tokai Univ. and MRI, are carrying out the single station earthquake observation near the Suruga Trough axial region, east end of a possible near-future Tokai Earthquake, using pop-up type Ocean Bottom Seismographs (OBSs) from October, 2011 to August 2014. After the single-station observation, we are conducting tripartite observation of three or four OBSs. Deployment and recovering of the OBSs are repeatedly conducted every three months using small work boat with about 20 ton ages of Tokai Univ. In the Suruga Trough axial region, seismicity became active since-years ago
