Developed land damaged during the 1978 earthquake was again damaged during the 2011 off the Pacific coast of Tohoku Earthquake. In the Midorigaoka district, there was no damage in 1-chome because it was restored considering deep and shallow sliding. Damage in 3-chome was a little severe than that in 1978 because only landslide reducing pile was installed.
