The prefectural governments of Shizuoka, Yamanashi and Kanagawa adopted the first comprehensive evacuation plan on Thursday to prepare for a possible eruption of Mount Fuji, Japan's highest peak . The evacuation plan calls for 750,000 people to leave their homes in 14 municipalities of Shizuoka and Yamanashi due to lava and pyroclastic flows, as indicated in March 2013. Additionally, 470,000 people, mainly in Kanagawa, are expected to evacuate due to volcanic ash in the air, according to the top floor. It's just a matter of years Since the great Tohoku earthquake in March 2011, scientists have been observing Mount Fuji for signs of activity. Say no to plagiarism.

So the pressure in Mount Fuji's magma chamber is now higher than in 1707, the last time the nearly 4,000-metre-high Japanese volcano erupted, leading volcanologists to speculate that disaster is imminent. According to retired professor Masaaki Kimura (professor emeritus of the Faculty of Science, Ryukyus University, Okinawa, Japan) this and other recent phenomena indicate that an eruption of Mount Fuji should have occurred in 2011 with a margin of error of four years ends in 2015. In 2000 and 2001 a series of low-frequency earthquakes were recorded beneath the volcano, leading to widespread predictions of an imminent strike. Since the March 2011 tsunami and the 6.4 magnitude earthquake that followed four days later, Japan has been on tenterhooks, and in May 2012 Masaaki Kimura warned that a massive eruption within three years was likely due to several factors important: steam and gas are emitted from the crater, water eruptions are occurring nearby, huge holes emitting hot natural gases are appearing in the crater. nearby and finally, an alarm signal that prompted the professor to make the announcement, a 34 kilometer long fault was found under the volcano. The fault, experts suggest, could indicate a total collapse of the mountainside if another significant shift occurred, and would likely cause a collapse in the event of an eruption, triggering massive mudslides and landslides. Professor Toshitsugu Fujii, head of Japan's volcanic eruption forecasting team, says an eruption could cause chaos and carnage as far away as Tokyo. "Mount Fuji has been resting for 300 years now, and that's abnormal. It usually erupts somehow every 30 years. So the next eruption could be a large-scale explosive eruption. If there was a big eruption, the government fears that could cause more than $30 billion in damage to public health and agriculture. Volcanic rocks will fall near the mountain. Ash accumulations in some areas could reach 60 centimeters. Tokyo, 100 kilometers to the northeast, could also be covered in volcanoes Tokyo will be covered in a few centimeters of ash. Yokohama will be under 10 centimeters. Trains will stop, planes will not fly and millions of crops will be affected,” said Professor Toshitsugu Fujii. Geology Mount Fuji is located at the triple junction where the Amurian plate, the Okhotsk plate and the Philippine Sea plate meet. These plates form the western part of Japan, the eastern part of Japan and the Izu Peninsula respectively. Scientists have identified four distinct phases of volcanic activity in the formation of MtFuji. The first phase, called Sen-komitake, is composed of an andesite core recently discovered deep within the mountain. Sen-komitake was followed by "Komitake Fuji", a layer of basalt believed to have formed several hundred thousand years ago. About 100,000 years ago, "Old Fuji" was formed on the summit of Komitake Fuji. The modern, "New Fuji" is believed to have formed on the summit of Old Fuji approximately 10,000 years ago. The volcano is currently classified as active with low risk of eruption. The last recorded eruption was the Hōei eruption which began on 16 December 1707 (Hōei 4, 23rd day of the 11th month) and ended around 1 January 1708 (Hōei 4, 9th day of the 12th month) during the Edo period. The eruption formed a new crater and a second peak (called Hōei-zan after the Hoei era) halfway up its flank. Fuji vomited ashes and ashes which fell like rain on Izu, Kai, Sagami and Musashi. There have been no signs of an eruption since then. On the evening of March 15, 2011, a magnitude 6.2 earthquake occurred at a shallow depth a few kilometers from Mount Fuji, on its southern side. But there was no sign of an eruption, according to the Japan Meteorological Service. In September 2012, mathematical models created by the National Research Institute of Earth Sciences and Disaster Prevention suggest that the pressure in Mount Fuji's magma chamber could be 1.6 megapascals higher than in 1707. However, since There is no known way to directly measure Considering the pressure of a volcano's magma chamber, such research is only speculative. Historical eruptions of Mount Fuji Mount Fuji is the highest volcano in Japan. The mountain as it appears now is the "New Fuji Volcano", which began erupting about 10,000 years ago. Below the "New Fuji Volcano" are the "Old Fuji Volcano", active between 100,000 and 10,000 years ago, and the "Komitake Volcano", active 700,000 years ago. Komitake There has been much volcanic activity in the vicinity of Mount Fuji for several million years. At the location occupied by today's Mount Fuji, a volcano known as Mount Komitake (小御岳火山), literally meaning "small mountain volcano", became active 700,000 years ago. During this period, another volcano, Mount Ashitaka (愛鷹山), in the area southeast of Mount Fuji, was also very active. The peak of the ancient Komitake volcano can be seen from the north face of Mount Fuji, at the fifth station, about 2,300 meters above sea level. Old Fuji About 100,000 years after becoming dormant, Komitake entered another period of activity. The volcano in this period is known as Old Fuji (古富士 kofuji). The older Fuji was known for having explosive eruptions, spewing large quantities of scoria, volcanic ash, and lava, forming a large mountain that reached a height of 3,100 meters (10,200 ft). New Fuji After the Old Fuji period, there were about 4,000 years of inactivity, which ended around 5,000 years ago, when Mount Fuji became active again; this period is known as New Fuji (新富士 shinfuji) and continues to the present day. New Fuji's eruptions display phenomena such as lava flows, magma, scoria, volcanic ash, collapses and lateral eruptions, leading it to be called "a department store of eruptions". The ash from New Fuji is often black and the eruptions are new in terms of the geological layers. Valuable data on Mount Fuji's activity is recorded in Japanese historical documents dating back to the 8th century onwards. It features a series of representative eruptions. Explosive eruptions before activity 3005 years ago There were four explosive eruptions in the Jōmon era, known as Sengoku scoria (Sg), Ōsawa scoria (Os), Ōmuro scoria (Om), and Sunazawa scoria (Zn). Since in the Mount Fuji area the wind normally blows from the west, the majority.
