Mount Fuji is about to break out?How terrible is the volcanic outbreak of different levels?

According to the Shiji Agency reported on the 19th, the Japanese Police Department has begun to make comprehensive preparations for Mount Fuji. According to the report, if the wind direction is the same as the wind direction of Mount Fuji in 1707, the volcanic ash may fall in the Tokyo Metropolitan area, which may disrupt road traffic and cause power outage.

The news attracted the attention of many netizens, and many people in the local area even started panic, and I don't know if it would be affected.

Some people in the industry have analyzed the information about Mount Fuji. In fact, the large -scale eruption in Mount Fuji is also 5 levels, up to 6 levels. It is similar to the Tanga volcano sprayed this year. The people do not have to panic. So how terrible is the volcanic outbreak of different levels?

01

How is the volcano formed?

One of the key elements turned out to be water! The seabed deep into the depths of the dive zone is no longer a simple state when the spine is solidified. The rock itself has changed due to the interaction with water, and then the water seeps into it through the cracks of the rock, and the temperature rises to the degree of boiling, prompting it to have a chemical reaction, thereby changing the structure of the rock. At the edge of the mainland, the remains of the organic creature that washed down from the land to form a layer of sediment, covering the rocks. As this mixture continues to sink, it becomes more and more hot, and is squeezed by extreme pressure -at a depth of 50 kilometers, the pressure is 15,000 times the surface atmospheric pressure, and the temperature has reached hundreds of degrees Celsius.

All these factors were added together, squeezed out the water in the rock and flowed into the mantle layer. There, the effect of water is like sprinkling salt on ice -promoting the mantle melting. Around the rock clumps fell from the rock ring, at the beginning, it was a melting magma of the stars, and then gradually spread. Because the melting magma is lighter than solid rocks, these melted substances gradually float, slowly penetrate the crust, and form a series of volcanic volcanoes on the previous sinking seabed.

Volcano outbreak of different levels

The most mild volcanic explosion method is to continuously release lava from the position of the expansion of the ocean ridge. A typical example is the Hawaii Islands volcanic chain, which also illustrates the nature of their often outbreaks. These lava is almost a basalt in a liquid state. Because these liquids are very rare, and various gas can easily form air bubbles and overflow, the pressure will not reach the extent of the large volcanic explosion scene. A large amount of lava fills the crater. On its surface, global physicists can observe that large pieces of material that have been solidified float on it -this is a model of a sector structure process. At the edge of the destructive plate, there are also some sections sliding side by side, like a miniature San Andreas fault.

What is larger than this volcanic burst is the outbreak of Starlon Bolly volcanic, and its name comes from Starlon Bolly Volcano, which is a volcanic island located between the Italian mainland and Sicily. Compared to the lava flow out of the Hawaii volcano, the basalt flowing from here is thicker and thicker, which makes the gas formation of gas larger, and then ruptured at a frequency of one minute, causing a micro volcanic burst. In these outbreaks, the semi -melting and melting magma was bombed into the air. Sometimes these magma splashed outside the crater and flowed to the mountain a little.

But in general, the Starlon Bolly volcano is noisy enough, but it is not very dangerous. One of the more universal basic laws is that the shorter the outbreak interval, the lower the risk of volcanic. There are two villages only a few kilometers away from the volcanic exit; the Etner volcano on Sicily is another example. However, the Starlon Bolly volcano is not limited to the Mediterranean region. The Erics volcano far away in the Antarctic region is another example of this type of volcano.

03

Burkano volcano

The first truly dangerous volcano is probably in the middle of the category table. This is also the origin of the English word of volcano -Wulcano volcano, located on a small island in northern Sicily. (Many volcanic prototypes are located in the Mediterranean, which is just because scientists first studied the volcano from there, there is no other reason.)

Like other volcanoes, Mount Wulcano is only intermittently active, but once it starts, it is more spectacular than any Stron Borley volcano. The outbreak of the Wulcano -type volcano can last for several months. The sprayed solid substances are spuned, and a large amount of volcanic ash is generated, and these volcanic ash blows from the heat from the volcanic mouth to the atmosphere. Although the Wurcano volcano often produces magma flow, the general volcanic ash is even greater. The volcanic ash may spread in a large scale, and it will last for a long time to settle down.

04

Vesuway volcano

The subsequent Vesuway volcanic eruption was named after the Vesuway volcano near Naples. It is like a more extreme Wurkano -type volcanic eruption, and the continuous air flow and volcanic ash rise to a higher atmosphere. Interestingly, because the power of this explosion is straight up and down, and the volcanic ash will float very far, the outbreak of Vesuwei's volcanic burst is less destructive to the surrounding areas compared to the Wurkano -type volcanic eruption. But the situation is not always the case.

05

Perey volcanic eruption

There are two names in the fifth type of volcanic eruption, or sometimes these are two kinds of sub -types that are not very distinguished. A seed type is the erection of the Preditual volcano, named after the Prey volcano in Martinik Island in the Caribbean region. This is a violent outbreak. A large amount of thermal gas and dust clouds ejected will flow down along the hillside and devour all unfortunate towns and villages along the way. Sometimes these sprayed heat is also known as Nuées Ardentes. This French term means "glowing cloud", but usually we still call it volcanic debris flow. 06

Plood -type volcanic eruption

Another type of seed, or the other name, is the outbreak of the Plink -type volcanic, named after the ancient Roman scholar Plints -he died in the Vesuway volcano explosion in 79 AD, which was buried in the ancient city of Pompeii That time. The huge amount of dust and gas cloud columns broke out that time, and the hot group of light -emitting substances also rolled down the hillside.

In this type of term, the outbreak of the Plinger -type volcanic eruption is the most violent one of all volcanic eruptions; the erey volcanic eruption is a simplified version of the Plinger -type volcanic eruption, which is slightly smaller. The only difference is that most of the energy outbreaks of the Plinger -type volcano are vertical and upward, while the energy outbreak of the erey volcanic outbreak is in all directions.

Considering their popularity in popular literature and mythology, one thing may be surprising: there are only about 500 active volcanoes worldwide globally, and the average of less than 25 will erupt on average each year. But even a gentle volcanic eruption will have an eye -catching effect, making the "actors" of these geological phenomena have always attracted our attention. Correspondingly, geologists have a series of image and interesting names for these things erupted from the volcano.

Volcanic bullet

"Volcano" is a solid or semi -solid lava block, which may be larger than one person. It is thrown out from the crater hundreds of meters away: if the appearance of the volcanic bullet is solidified and the interior is still sticky, then it will be due to internal air pressure due to internal air pressure. Or the impact when hitting the ground burst, which is called "bread leather volcanic bullet"; ribbon -shaped lava is solidified by air plastic when flying in the air. The shape rock block is called "spherical bomb"; the slender strip is called "spindle -shaped bomb"; there are also some that have not been solidified before landing, and they are splashed around the ground.

Those small pieces of eruptions are called "volcanic gravel" as big as gravel and pebbles. Those smaller are simply called "volcanic ash". All solid substances erupted from the volcano are generally called "volcanic debris." And those smaller solid particles can cause the greatest harm.
