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.

The Relationship

Road infrastructure damage due to extreme ground excitations during theMarch 2011 Tohoku earthquake was assessed and 161 items of damage road structure data were classified into three types of failure modes: road surface and embankment damage items, road surface crack items and road subsidence items. We then compared a damage ratio, which is defined by the number of damage points divided by total road length, to the estimated spatial distribution of JMA instrumental seismic intensity. The maximum damage ratio for the 161 damage data items is 0.0290 points/km compared to a JMA instrumental seismic intensity of 5.8. Last, we developed damage functions for road infrastructures subjected to extreme ground excitations, which describe the relationship between the damage ratios and seismic intensity.
