In Japan, very strong seismic excitations such as The 2011 Off The Pacific Coast Tohoku earthquake on March 11, 2011 (magnitude 9.0, maximum recorded ground acceleration 2,933 cm/s~2) have to be considered. It is also true that Japan has very strong typhoons, e.g. Typhoon Maemi passed over the Miyakojima Island on September 10 and 11, 2003, and a 3s gust wind speed exceeding 90 m/s was recorded (Cao et al., 2009).
