| | Abstract | | Aftershock observation of the 2011 off the Pacific coast of Tohoku Earthquake was performed, using 3C high density array seismometers at Aratozawa dam site in Miyagi prefecture, where the large scale landslide occurred associated with the 2008 Iwate-Miyagi Nairiku Earthquake. We are trying a combined study of the geological structure by reflection seismic survey and high density array observation of earthquake to solve the subject of landslide triggered by the earthquake. |
