06/09/2012 13:00 The conference according to a country and a local self-governing body in order to prepare for the large-scale eruption of NHK news' Mt. Fuji is the inauguration '.
In order to prepare for the large-scale eruption of Mt. Fuji, the conference by the country and a local self-governing body will be launched, and future disaster measures, such as making an evacuation plan in a wide area and implementation of an emergency drill, will be worked on.
In order that a conference might discuss disaster measures when Mt. Fuji erupts, it was newly prepared, and the volcanic specialist etc. participated in the first meeting held in Shizuoka at the disaster prevention person in charge of each prefecture in Cabinet Office, the Meteorological Agency, Shizuoka, Yamanashi, and Kanagawa, and it.
In the meeting, Shizuoka University [ which serves as a committee ] Professor Masato Koyama expressed the opinion, and it "has turned out [ the quantity of the lava which came out by the past major volcanic eruption is considered until now, and it depended, and / many ] by the newest research."
05/22/2012. University of the Ryukyus Emeritus Professor Masaaki Kimura.
Associate Professor Masashi Tsukui of the Chiba University graduate school physical science graduate course
The possibility of an eruption will be [ with a Mt. Fuji of less than three years ] high.
Many signs of the eruption have appeared in Mt. Fuji.
The precursor of the eruption "a water eruption" which that University of the Ryukyus Emeritus Professor Masaaki Kimura pays his attention generates from the northeast of the crater in Mt. Fuji to southwest.
This unfamiliar "water eruption" is a phenomenon in which water and hot water blow off, instead of lava.
Although the magma which is underground is pushed up by plate activity and the usual eruption occurs on the broken surface of the earth, as for a water eruption, not magma but groundwater blows off.
It is what that meets in the state where there are not an eruption and a not much change as a situation of this volcano in fact.
It is said that water is springing every several months over two years or more, and the water level is high suddenly around Fujinomiya also in the northern Five Lakes of Mount Fuji.
Furthermore, it is said that the omen of the eruption of Mt. Fuji has taken place also in Kawaguchiko.
It is natural gas spouted from the bottom of a lake in Kawaguchiko.
According to Emeritus Professor Kimura
"Since it is not volcanic gas which is blowing off directly from magma, there are some persons who do not realize it as the precursor of an eruption, but it is increasing extremely about one year before.
Moreover, the hole big several places was vacant on the exercise background of the Self-Defense Forces on the east slope in Mt. Fuji, and Centigrade 40 and 50 gas emission have come out from there to it.
It will be hard to think of that these happen at the period also including a water eruption in addition to the omen of an eruption.
It seems that considering these situations a possibility that an eruption will occur in less than [ other 3 year ] is quite high. "
Things.
It says [ that the wonderful phenomenon of driving a traveler's compass mad has also been reported, and ] Emeritus Professor Kimura's basis.
a few -- fearful -- having become .
.
.
It is in others.
spring arrival is told The pattern "Nouchou" of unmelted snow appeared on January 31 of a severe winter (phenomenon of usually appearing [ from / the middle of May in which a thaw is greeted / at the June time ]), and the lake of the phantom which is not seen appeared by Fujikawaguchikomachi of the Mt. Fuji foot usually in summer last year.
It is referred to as that the phenomena same at 99 places, such as a said district, are checked around Fujinomiya that there are many directions currently afflicted by the springwater spouted from under the floor of a kitchen or sitting room around from summer last year, and water blows off from a well etc.
Furthermore, an associate professor of the Chiba University graduate school physical science graduate course, Mr. Masashi Tsukui, has indicated that there will be a close resemblance between the present situation and the 9th century in the first half of the Heian period.
According to Associate Professor Tsukui
"Although the eruption occurred in Oshima in Miyake-jima in 1986 in 1983 and 2000, the major volcanic eruption has occurred in Izu Islands also in the 9th century.
And the earthquake of western Tottori in 2000 and Niigata Chuetsu in 2004 has occurred at the same place also as the 9th century.
When it goes back, the earthquake which occurred in Niigata in 1964 and the central Sea of Japan in 1983 is also the same.
And the thing which this East Japan great earthquake occurred at the place with the Jyokan Sanriku earthquake which is the earthquake greatest in the 9th century."
Furthermore, according to Mr. Tsukui, it is already with "the interlocking earthquake of Tokai, the southeast sea, and Nankai" to generate in the 9th century and to have not occurred in the second half of the 20th century.
"An eruption of Mt. Fuji"
It is indicated that it is .
In addition to this, the number of times of the earthquake has increased extraordinarily after - East Japan great earthquake.
- The interval of an eruption of Mt. Fuji is 200 years from 100.
However, it has become silent for 300 years after a Houei eruption takes place in 1707.
- The low-frequency earthquake has increased in the deep place of underground.
It seems that a low-frequency earthquake happens by underground magma.
- GPS data has change in 2008 and 2 cm of distance of Gotemba and Fujinomiya spread.
This is considered to be the proof in which magma has gone up.
- An accident is checked in the cave called the "windhole" of the Mt. Fuji foot, the icicle of a noted product melts, and it is small.
- The "continuation permafrost layer" of the Mt. Fuji top already disappears.
Every phenomenon is checked.
According to assumption of the hazard map of Mt. Fuji examination committee of Cabinet Office, it is supposed by the eruption of Mt. Fuji that about 2?10-cm volcanic ashes will lie even in Tokyo.
In the scenario expected, the airplane by which 14,600 km and operation become impossible in the road whose passing becomes impossible with lava, volcanic ashes, etc. is expected for the power failure by No. 515 per day and short circuit to also attain to 1,080,000 households, and it is assumed that the total damage amount amounts to 2,500 billion yen.

'富士山の大規模な噴火に備えるため、国と地元の自治体による協議会が発足'
富士山の大規模な噴火に備えるため、国と地元の自治体による協議会が発足し、広域での避難計画作りや防災訓練の実施など、今後の防災対策を検討していくことになりました。 協議会は、富士山が噴火した場合の防災対策を話し合うために新たに設けられ、静岡市で開かれた初会合には、内閣府や気象庁、静岡、山梨、神奈川の各県の防災担当者、それに火山の専門家などが参加しました。 会合では、委員を務める静岡大学の小山真人教授が意見を述べ、「最新の研究では、過去の大噴火で出た溶岩の量がこれまで考えられていたより多かったことが分かってきた」
05/22/2012. 琉球大学の木村政昭名誉教授。千葉大学大学院理学研究科の津久井雅志准教授
富士山 3年以内に噴火の可能性が高い.
富士山に噴火の兆候がいくつも現れています。
琉球大学の木村政昭名誉教授が着目しているのが、富士山の噴火口の北東から南西にかけて発生する「水噴火」という噴火の前兆現象。
この聞きなれない「水噴火」とは、溶岩が噴き出すかわりに、水やお湯が噴き出す現象です。
通常の噴火は地下にあるマグマがプレート活動によって押し上げられ、割れた地表で発生しますが、水噴火はマグマではなく地下水が噴出します。
実はこれ、火山の状況としては、噴火とあまり変わりのない状態にあるそうなんです。
富士宮市周辺では2年以上にわたって数か月おきに水が湧いていて、北部の富士五湖も水位が突然高くなっているそうです。
さらに、富士山噴火の予兆は河口湖にも起きているといいます。
それは河口湖の湖底から噴出する天然ガス。
木村名誉教授によれば
「マグマから直接噴出している火山性のガスではないので、噴火の前兆現象と捉えない人もいますが、１年ほど前から極端に増えています。また、富士山の東斜面にある自衛隊の演習地に数か所大きな穴が空き、そこから摂氏４０、５０度の噴気が出ています。水噴火も含め、これらが同時期に起こるのは噴火の予兆以外に考えにくいでしょう。これらの状況を考えると、向こう３年以内に噴火が起きてしまう可能性はかなり高いと思われます。」
とのこと。
木村名誉教授のもとには旅行者のコンパスを狂わすという不思議な現象も報告されてきているといいます。
少し怖くなってきましたネ。。。
他にもあります。
春の到来を告げる 残雪の模様「農鳥（のうとり）」が厳冬の１月３１日に出現したり（通常は、雪解けを迎える５月中旬から６月ごろにかけて現れる現象）、昨年夏には、富士山麓の富士河口湖町で普段はみられない幻の湖が姿を現しました。
富士宮市周辺では、昨年の夏ごろから台所や居間の床下から噴出する湧き水に悩まされている方が多く、井戸から水が噴き出すなど、同地区などの９９カ所で同様の現象が確認されていると言います。
さらに、千葉大学大学院理学研究科准教授の津久井雅志氏は、現在の状況は平安時代前半の９世紀に酷似していると指摘しています。
津久井准教授によれば、
「１９８３年と２０００年に三宅島で、１９８６年には大島で噴火が起きましたが、９世紀にも伊豆諸島で大噴火が起きています。そして２０００年の鳥取県西部、２００４年の新潟中越の地震は、９世紀にも同じような場所で発生している。さかのぼると、１９６４年の新潟、１９８３年の日本海中部で起きた地震も同じ。そして、９世紀最大級の地震である貞観三陸地震があった場所で今回の東日本大震災が起きたんです」
とのこと。
さらに津久井氏によると、９世紀に発生し、２０世紀後半に起きていないのは、もはや
”東海・東南海・南海の連動地震”
と
”富士山の噴火”
だけなのだと指摘しています。
そのほかにも、
・東日本大震災後、地震の回数がケタ違いに多くなっている。
・富士山の噴火の間隔は１００年から２００年。しかし、１７０７年に宝永噴火が起こってからは、３００年間沈黙している。
・地下の深いところで低周波地震が多くなっている。低周波地震は、地下のマグマによって起こると思われている。
・２００８年ＧＰＳデータに変化があり、御殿場と富士宮の距離が２センチ広がった。これは、マグマが上昇してきた証拠ではないか、とも考えられる。
・富士山麓の「風穴」と呼ばれる洞窟に異変が確認され、名物の氷柱が溶けて小さくなっている。
・富士山頂の「連続永久凍土」が既に消滅。
などの現象も確認されています。
富士山が噴火たらどうなるのでしょうか？
内閣府の富士山ハザードマップ検討委員会の想定によると、富士山の噴火により、東京でも２～１０cmほどの火山灰が降り積もるとされています。
予想されるシナリオでは、溶岩や火山灰などによって通行不能になる道路は１万４６００km、運行不能になる飛行機は１日あたり５１５便、漏電による停電は１０８万世帯にも及ぶと見られ、その被害総額は２兆５０００億円にのぼると想定されています。
