Abstract

We collected data on the March 11, 2011, Great East Japan Earthquake by surveying web sites related to power failures during 2011 off the Pacific coast of Tohoku (northeastern Japan) and, in addition, by interviewing local government sectors and Tokyo Electric Power Company (TEPCO) branch office personnel. We quantify two damage ratios for power failures for subject municipalities defined by the ratio of the number of affected households and houses in a city to the number of related households and houses. This revealed the dependence of damage ratios on seismic intensities induced in subject municipalities. Damage functions related to power failures are then developed.
