MESSAGE

Recently, big earthquakes over 8 magnitude, like the 2011 East Japan Great Earthquake and the 2008 Wenchuan Earthquake in China, had occurred in the Asian region. These earthquakes caused serious impact on peoples's life.
I believe that conducting researches and educational activities against earthquake disasters and creating safe cities are urgent subjects and my missions as a researcher engaged in the earthquake engineering.
So I launced the reserch about the seismic stabilities of ground and underground structures.
I hope many students in Asian countries would join us and study hard with me!
