relation to earthquake

    The relevance of the eruption of Mt. Fuji and the big earthquake in a neighboring area is pointed out by many researchers. Although the example which the Kanto earthquake and the Tokai earthquake which occur in the eruption of Mt. Fuji and the subduction zone in the Philippine Sea Plate approached in time, and generated is seen past several times, especially remarkable things are the 1703 Genroku Kanto earthquake and the 1707 Houei Tokai earthquake, and the Houei eruption in December, 1707.
    According to the place made clear from history record, just behind the Genroku earthquake in 1703, shake is observed in Mt. Fuji, and it is thought that the magma directly under Mt. Fuji went up to the quite shallow portion, and generated swarm earthquakes.
   Subsequently, the Houei eruption has taken place 49 days after the occurrence of the Houei earthquake on October 28, 1707.
    On the other hand, the example which was not connected also has the occurrence of a big earthquake in activity activity of Mt. Fuji, and the Tonankai earthquake of Showa, etc. are mentioned.
    In March, 2003 (Heisei 15), the Central Disaster Prevention Council announced that the amount of damage of the Tokai earthquake includes the indirect damage caused by cutting into pieces of traffic, etc. of 26 trillion yen only owing to direct damage with 37 trillion yen.
    However, when sudden fall and sliding land price of a national bond and a stock, the downturn of mental consumption, the rise of a premium rate, etc. are added, there is also trial calculation of 56 trillion yen.
The price of a national budget of Japan of tax revenues is about 40 trillion yen of the half but about 80 trillion yen.
    The remaining most are government bond issuance and a debt request, and, in a country and the self-governing body of 700 trillion yen or more in all, there is the total debt amount.
Compared with advanced nations doing suitable fiscal management for 90 percent of budget order depending on tax revenues, it is a surprising debt hell power.
Probably, at most 50 trillion yen of sensible budget constructs are a limit.
The damage of the Tokai earthquake is equal to an entire national budget suitable for national power of Japan.
    Although it is serious damage, a possibility of not finishing it as this in fact is high.
Previous assessment of damage is because the influence of the damage and the damage caused by rumors of a nuclear power plant, and the Tonankai and Nankai earthquakes and the Fuji volcanic eruption the danger of the Tokai earthquake and linkage is indicated to be is excepted.
    There is no example which a Tonankai earthquake did not merge to the past Tokai earthquake, and there is also no example in which an Nankai earthquake was not interlocked with a Tonankai earthquake. Moreover, many volcanologists think that the Fuji volcano carries out an activity resume by the following Tokai earthquake.
    The zone which extends from the Suruga bay "Suruga trough" and the "Nankai Trough" to the offing of Shikoku is a place which must look out for a big earthquake most in Japan.
The earthquake called the Tokai earthquake, a Tonankai earthquake, and an Nankai earthquake at intervals of 90 to about 150 years has generated this zone.
Although this "Tokai, Tonankai and Nankai earthquake" has the epicentral area different, respectively, it is a fearful earthquake which may chain and occur.
    Since it is an earthquake which will certainly occur in the near future, careful cautions and measure are required.
    Next, let's see the Tokai, Tonankai and Nankai earthquake which occurred in the past. The Tokai, Tonankai and Nankai earthquake in 1707 It is the greatest earthquake that was called the Houei earthquake and occurred in Japan.
Magnitude 8.4 on the Richter scale. It shifted all at once, and the plate from the offing of Tokai to the offing of Shikoku is wide range, and caused the catastrophic disaster.
    The dead reached collapse of 20,000 or more people and a house 60,000 or more. Mt. Fuji has also erupted according to this earthquake. The Tokai, Tonankai and Nankai earthquake in 1854 It is called Tokai and the Nankai earthquake of Ansei. Magnitude 8.4 on the Richter scale.
    The Nankai earthquake occurred 32 hours after the Tokai earthquake.
The dead are the earthquake which was serious.
The Nankai earthquake of magnitude 8.0 on the Richter scale occurred two years after the Tonankai earthquake of Tonankai-and-Nankai-earthquakes magnitude 6.8 on the Richter scale in 1944-1946. The dead amount to 2500 or more persons, and are the earthquake which were as for damage, such as a fire.
    Aren't some noticed from this?
Although the Tokai, Tonankai and Nankai earthquake occurs at intervals of 90 to about 150 years, the Tokai earthquake has not occurred in the earthquake of 1944.
    Saying is a situation which is not wonderful, whenever 150 years or more will already have passed and it may carry out the Tokai earthquake occurrence, after the last Tokai earthquake occurs.
From it being an earthquake massive in the past in the same epicentral area, the Tokai earthquake is predicted to be seismic intensity of seven or more in the wide range, and the damage beyond a Kobe earthquake is assumed.
