Abstract
The great earthquake of M9.0 and huge TSUNAMI attacked East Japan at 14:46 on March 11, 2011. The Internet communication contractor's base station, and equipment of an electric power company, etc. flowed out and sank. Therefore, communication was intercepted completely in Ishinomaki city. Ishinomaki Senshu University also suffered the damage which does not have experience in the past. In this research, I report the disaster situation and repair work in the Ishinomaki Senshu University Information and Communication Technology Center (ICTC). Moreover, I clarify also about issues of ICTC under The Great East Japan Earthquake.
