| Outline of Final Research Achievements |
This research investigated implementation of earthquake disaster prevention system based on modelling enhancement of real-time disaster prevention information as Structural Health Monitoring (SHM) and Earthquake Early Warning (EEW) using data obtained by the real-time earthquake observation network extended at public buildings in Miyagi-prefecture and surrounding area.
As for SHM, based on the long-term observation data of buildings experienced the 2011 Tohoku earthquake, new findings on dynamic characteristics before, during and after the earthquake have been obtained together with those on amplitude dependency and seasonal change of dynamic characteristics. Regarding EEW, as real-time ground motion prediction method using front-site waveform information, data assimilation technic and RVM have been investigated.
These research results were presented inside and outside Japan and also utilized for earthquake disaster prevention education.
