Inventions...
There are many inventions. But, as far as I know, the sites of inventions are written in Japanese. Can you read them?
1) We will know 10 seconds (ave.) before quake. The wave of earthquake consists of S-wave(main quake) and P-wave(fast and small). If the system catch the p-wave, it calculate the center and scale. And, it will be broadcast on TV/internet/cellphone(new model). This had been tested since several years ago, and has already proved when Chuuetsu Earthquake came.
Cellphone's system: http://www.au.kddi.com/manual/w61sh/misc/misc01.html
2) Above system has already applied to trains. The system stops trains before large quake.
