| Outline of Final Research Achievements |
Land conditions of the liquefied sites induced by the 2011 off the Pacific coast of Tohoku Earthquake, the 2013 April 13th Earthquake in Awaji Island area and the 2016 Kumamoto Earthquake were investigated by using the geographical information system (GIS) and the time-serial geospatial information (map and aerial photo). A large number of the liquefaction caused by the 2011 off the Pacific coast of Tohoku Earthquake and the 2013 April 13th Earthquake in Awaji Island area were occurred in the reclaimed land in coastal areas, former river channels and ponds, and the refilled sand-gravel pits. These sites were artificial land consists of the man-made sand fills and developed after the 1950's. A large number of the liquefaction damages were concentrated on the zonal area located on the natural levee between the Shirakawa River and the Kasegawa River. Sand boils were also observed at the refilled lot of gravel pits along the Midorikawa River.
