Research on the Earthquake Resistance of Buddha Statues Enshrined in Hokke-do, Todai-ji Temple
In Hokke-do at Todaiji temple, a lot of Buddha statues made of dry-lacquered and clay, including “Fukuukenjaku Kannon,” are enshrined on the shumidan. It is estimated that a major earthquake will occur in the Nara Basin, so the possibility of earthquake resistance and planning of countermeasures are important for the Buddhist statues in Hokke-do. The Center for Conservation Science and Restoration Techniques measured the 3D shpae of Buddha statues and preliminary survey for stability of the Hokke-do and its shumidan.
For 3D measurement, we adopted the simple shape measurement system based on stereo camera motion photography (currently being developed by Toppan Printing Co., Ltd.). We newly applied wireless system, so safe measurement became possible on the shumidan. As a result, measurement of the six statues was completed.
A specialist in wood structures was invited for preliminary survey for stability of the Hokke-do and its shumidan. We hope to use the results to continue the ambient vibration survey on the shumidan and temple buildings.
