- Abstract
- The Miyagi-Ken-Oki, Japan earthquake caused considerable damage in the city of Sendai and its surrounding areas. As information became available, it became obvious that Sendai constituted a good model of a modern city in the United States such as San Francisco or Seattle. The city has modern, instrumented, steel and reinforced concrete buildings up to 20 stories high and has an operating nuclear power plant complex, consisting of six units, located nearby at Fukushima. The areas surrounding the city were subjected to peak ground accelerations in the range of 1/5g, 1/4g, and 1/3g. There were failures of large tanks, oil spills, dike and bridge failures, a gasholder failure, disruption of utility service, and landslides. The reports compiled here are of a reconnaissance nature only and are not intended to analyze or to reach conclusions about what was seen but rather to report by photos, words, and numbers what happened and what did not happen. Reports cover the following topics: Seismicity; strong-motion earthquake records; liquefaction and damage to dikes; landslides resulting from the earthquake; engineering aspects; architectural aspects; and social effects and government response.
