The prefectural governments of Shizuoka, Yamanashi and Kanagawa on Thursday adopted the first comprehensive evacuation plan to prepare for a possible eruption of the highest Mount Fuji summit of Japan. The evacuation plan calls for 750,000 people to leave their homes in 14 municipalities in Shizuoka and Yamanashi due to lava and pyroclastic flows, as reported in March 2013. In addition, 470,000 people, mainly in Kanagawa, are expected to be evacuated due to volcanic ash in the area. the air, according to the last plan. Just a few years Since the Great Tohoku Earthquake in March 2011, scientists have been monitoring Mount Fuji for signs of activity. Say no to plagiarism.

The pressure in Mount Fuji's magma chamber is therefore now higher than it was in 1707, the last time the nearly 4,000 meter high Japanese volcano erupted, leading volcanologists to speculate on the imminence of a catastrophe. According to retired professor Masaaki Kimura (professor emeritus, Faculty of Science, University of the Ryukyus, 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. ending in 2015. In 2000 and 2001, a series of low-frequency earthquakes were recorded beneath the volcano, leading to many predictions of an imminent blow. Since the March 2011 tsunami and subsequent 6.4 magnitude earthquake four days later, Japan has been on in May 2012, Masaaki Kimura warned that a massive eruption within three years would be likely due to several major factors: steam and gases are emitted from the crater, water eruptions occur nearby, massive holes emitting hot natural gases appear in the surroundings and finally, warning sign which prompted the professor To make this announcement, a 34 km long fault was discovered under the volcano. Experts say the fault could indicate a total collapse of the mountainside if there is another significant change, and it would likely cause collapse if an eruption occurs, leading to huge landslides and mudslides. Professor Toshitsugu Fujii, head of Japan's volcanic eruption forecasting committee, says an eruption could cause chaos and carnage as far away as Tokyo. "Mount Fuji has been dormant for 300 years now, and that's abnormal. It usually erupts in some form every 30 years, so the next eruption could be a large-scale explosive eruption. there is a large eruption, the government fears it will occur Volcanic rocks will fall near the mountain and cause more than $30 billion in damage to public health and agriculture. some areas could reach 60 centimeters. Even Tokyo, 100 kilometers to the northeast, could be covered in volcanic “ash. Tokyo will be covered in a few centimeters of ashes. Yokohama will be less than 10 centimeters away. 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 Amur plateof Okhotsk and the Philippine maritime plate. 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 Mount Fuji. The first phase, called Sen-komitake, is composed of a recently discovered andesite core 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 atop Komitake Fuji. Modern "New Fuji" is believed to have formed on top of Old Fuji around 10,000 years ago. The volcano is currently classified as active with a low risk of eruption. The last recorded eruption was the Hōei eruption which began on December 16, 1707 (Hōei 4, 23rd day of the 11th month) and ended around January 1, 1708 (Hōei 4, 9th day of the 12th month) during the period Edo. The eruption formed a new crater and a second peak (named Hōei-zan after the Hoei era) halfway up its flank. Fuji spat out ashes and cinders which fell like rain on Izu, Kai, Sagami and Musashi. Since then, there have been no signs of an eruption. On the evening of March 15, 2011, a magnitude 6.2 earthquake occurred at shallow depth a few kilometers from Mount Fuji, on its southern slope. But according to the Japanese Meteorological Service, there were no signs of an eruption. As of September 2012, mathematical models created by the National Research Institute for Earth Sciences and Disaster Prevention suggest that the pressure in Mount Fuji's magma chamber may be 1.6 megapascals higher than in 1707. However, as there is no known way to directly measure 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 today is the "New Fuji Volcano", which began erupting around 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”, which became active 700,000 years ago. Komitake There has been strong volcanic activity near Mount Fuji for several million years. At the site occupied by present-day Mount Fuji, a volcano known as Mount Komitake (小御岳火山), literally meaning "small mountain volcano", became active 700,000 years ago. At that time, another volcano, Mount Ashitaka (愛鷹山), located in the area southeast of Mount Fuji, was also very active. The summit of the ancient Komitake volcano is visible from the north face of Mount Fuji at the fifth station, about 2,300 meters (7,500 ft) above sea level. Old Fuji About 100,000 years after being become inactive, Komitake enters another period of activity. The volcano from this period is known as Old Fuji (古富士 kofuji). Ancient Fuji was known for having explosive eruptions, throwing up large quantities of slag, 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, ending about 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 feature phenomena such as lava flows, magma, cinders, volcanic ash, collapses and secondary eruptions, earning it the name of "a big store of eruptions". The ashes of New Fuji are often.
