A year ago, on February 22, 2011, Christchurch, N.Z. experienced one of the worst earthquakes in their history causing 185 deaths, among which were 28 Japanese language students trapped in the CTV building.

Though the intensity of earthquake was middle class of M.6.1, the damage of buildings was far too big. M6.1 class earthquakes are happening often around Japan Archipelago. (The last East Japan earthquake of March 11, 2011 was M9.0 scale earthquake.) So you may wonder why this is so. I hope you can understand more about earthquakes and your prevention from it watching the video attached.

Dr. Osamu Joh, retired professor of engineering specialized on ‘seismic design of buildings’ of Hokkaido University explains in details on the issue in the three categories:

1) Prediction of seismic intensity on the ground (you understand what happened in Christchurch, where the ground was sandy and swampy)

2) Seismic design of buildings in Japan and their seismic performance (why CTV bldg. Collapsed)

3) Safeguarding in rooms for earthquakes

On February 2012, Dr.Osamu Joh spread the ideas of prevention of Earthquakes in the TEDx event in the downtown Sapporo.

About TEDx

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
