Another research team reported that nearly a quarter live in Japan's population below the Kanto Plain, Europe and Asia, the Pacific and Philippine Sea plate at the junction of three in the next 30 years, the occurrence of more than 7.3 magnitude earthquake probability, may be to reach more than 30%!
By the United States Geological Survey and Japan Ross Stein Active Fault Research Center, led by Shinji Toda of the research team, in the end of last year in San Francisco organized by the American Geophysical Union (AGU) fall meeting, published in the past occurred in the Kanto region 300000 seismic research results show that due to a break of the Pacific plate subduction under the card in the region, resulting in the massive earthquake occurred periodically continued.
Kanto region to observe the distribution of sea-bands can be traced back to the past七千年large-scale earthquake occurs roughly every four hundred years is 17 times the frequency of large earthquakes occurred in the repeat. For example, in 1923 and 1703 more than twice the size of eight earthquake, resulting in the Kanto region over the death of hundreds of thousands of people. If more than 7.3 magnitude earthquake coupled with the frequency (for example, in 1855), then the next 30 years in Tokyo, a major earthquake hit the bottom of the chance to be as high as more than 30%.
The future unless the broken plate subduction completely, otherwise the frequency of occurrence of a major earthquake there will not be much change. But the chances for us, it seems a bit embarrassing, it is not high enough to be worried about the point where every day, but not as low as can be ignored. In short, we must always remind ourselves that there is not a time bomb on our feet, as to when it would burst open to, it is difficult to say ah!
