平成23年（2011年）東北地方太平洋沖地震における企業の被災状況分析

抄録

Information on damage of companies caused by the 2011 off the Pacific coast of Tohoku earthquake was collected by the use of released information, and the relations between the damage and JMA seismic intensity scales of the company location points were studied. The damage ratios to buildings and facilities increase with the higher JMA seismic intensity scale. Due to the tsunami damage, companies located in the coast areas such as material, energy, life and medical industries needed more recovery days than other companies in the inland areas such as electric, information, automobile, and machinery industries.
