Abstract:East Japan earthquake is the largest magnitude earthquake in recent years, the earthquake itself and the result of earthquake damage have many unique features. This report contains the site visit of the Sino-Japanese joint delegation and the main content of the related discussed issues. The first is the basic and main features of the East Japan earthquake, tsunami and scope, characteristics and severity made the highlights. Destruction of buildings in the earthquake disaster that are directly caused by the earthquake is not serious. In addition to the general earthquake situation and earthquake damage, the report specifically for the seismic characteristics and domestic concern, highlights the following contents. The long-period ground motion is a feature of this earthquake, and it describes its characteristics, impact and the issue to be examined; Energy-dissipated and seismically isolated technology development status and performance in the earthquake are described in detail, at the same time the issue of development of the damping and isolation is explained; It also explains the situation in the earthquake, experience and guide of seismic reinforcement works; Widespread concern in the seismic design of nuclear power plants, combined with the Fukushima nuclear power plant accident, has made a presentation; Finally, it describes the seismic countermeasures on building structures by construction authorities in Japan after the earthquake.
Keywords:East Japan earthquake; earthquake disaster; tsunami; long-period; energy-dissipation; seismic isolation; seismic reinforcement; nuclear power plant; nuclear disaster
