How to prevent volcanic eruptions? The hazards of volcanic eruptions

If classical geology is correct, then we can easily extract an inexhaustible supply of magmatic heat from the mid-ocean ridge. The method is to drill through the oceanic crust (6-8 km) next to an active volcano and install two large pipes, one of which will be filled with seawater and the other will spew high-temperature and high-pressure steam.

This will lead to the construction of a power plant. If the volcano can be extinguished, classical geology is correct. If there are enough such power plants, all the thermal energy of the mid-ocean ridge can be extracted, which will be an inexhaustible source of energy.

and will cut off mantle convection, seafloor expansion of energy. If successful, the plates will no longer move, the mountains will no longer rise, the earth will no longer tremble, and the continental terrain will become flat. This is a great geoproject, and if it can be realized, it will also prove that classical geology is correct.

Preventing volcanic eruptions is unrealistic, and we are so weak in the face of the power of the earth. There are many things that human beings cannot do, so they can only strengthen their awareness of prevention and minimize losses.

Upstairs, is it good for you to turn Earth into a death star, or is it good for humanity, or is it good for Earth?

It's just unreasonable.

Volcanoes can't be prevented, and they can only flee for their lives in front of volcanoes...

The upwelling of magma is driven by deep extrusion or the heat of mantle convection.

And neither of these things can be stopped

The hazards of volcanic eruptions are: 1. Affecting the global climate. Volcanic eruptions emit large amounts of ash and volcanic gases, which have a great impact on the climate.

2. Destroying the environment. The combination of volcanic ash and heavy rainfall from volcanic eruptions can create mudslides that can wash away roads, bridges, and inundate nearby villages and cities, leaving countless people homeless. 3. Triggering a tsunami.

An undersea volcanic eruption can trigger a tsunami that threatens people living near the coastline. 4. Trigger**. The lava flows from terrestrial volcanic eruptions can incinerate everything, not only changing the terrain and landform, but also causing ** and other secondary disasters.

Volcanic eruptions are a peculiar geological phenomenon, a manifestation of the movement of the earth's crust and one of the most intense displays of thermal energy on the surface of the earth's interior. It is the release of ejecta such as magma from a crater to the surface in a short period of time. Due to the large amount of volatiles contained in the magma, coupled with the confining pressure of the overlying rock layer, these volatiles are dissolved in the magma and cannot overflow, when the magma rises close to the surface, the pressure decreases, and the volatiles are released sharply, thus forming a volcanic eruption.

Volcanic eruptions are a peculiar geological phenomenon that is a manifestation of the movement of the earth's crust. Volcanic ash from volcanic eruptions is different from soot in that it is a small, hard particle that is insoluble in water. Inhalation of volcanic ash can cause damage to the respiratory tract and lungs in humans and animals, leading to respiratory diseases.

Volcanic ash can affect machinery and equipment, causing damage to vehicles, such as cars and airplanes. In addition, the eruption of a larger volcano can cause a large number of people**.

Once it erupts, the power is particularly violent. Because in this case, dim daylight and storms and even mud rain can plague the local population for months. When volcanic ash and volcanic gases are ejected into the air, they are dispersed by the wind over long distances.

This volcanic material can block out the sun, causing temperatures to drop.

What are the dangers to human beings after volcanic eruptions, there are many examples in some areas of the earth where volcanoes erupt frequently a long time ago.

The degree of damage of volcanic eruptions depends first of all on the way of volcanic eruptions, usually the first type of eruption is more harmful, while the other type of overflow eruption is relatively less harmful.

The so-called ** eruption is that the magma erupts in the form of **, and the flowing magma cannot be seen, but the mushroom cloud can be seen, and the size of the mushroom cloud varies from a few kilometers to dozens of kilometers.

In terms of scope, volcanic ash is a hazard that spreads to a relatively large extent after volcanic eruptions.

** eruptions produce eruption columns, and large eruptions (more than 10 km) will enter the stratosphere. Once in the stratosphere, volcanic ash spreads, and the first to be affected is the aviation sector. After a volcanic eruption, the eruption column also produces tiny aerosols.

Aerosols stay in the stratosphere for a long time and cover the Earth's atmosphere, like a giant umbrella to block the heat of Taiyuan Beihuyang. While a volcanic eruption is a thermal event in itself, it has a cold effect on the global climate.

Volcanic eruptions also produce large amounts of toxic gases, which endanger lives and destroy the environment in which the eruption is blowing. Volcanic eruptions bring with them high densities of greenhouse gases (also known as carbon dioxide) that can have an impact on people who do not have time to escape as they descend the hillside. In addition, a large amount of toxic fluoride and chloride can be fatal to residents in the affected areas in the short term.

In addition to volcanic ash, large-scale high-temperature lava flows of about 1000 meters and pyroclastic flows are one of the important hazards of volcanic disasters. Almost everywhere a lava or debris flow can reach, it is devastating. But usually their damage is localized, and the impact of the thousand-year-old eruption in Changbai Mountain is only within a 50-kilometer radius of the hail barrier.

There may be magma flowing near the volcano, which will have a severe impact on local production and life. If the eruption is severe, large or old volcanic ash enters the atmosphere and circulates through the atmosphere, causing regional anomalies in the global climate to be simplified, which has a great impact on agriculture.

It is easy to cause air pollution, causing a large number of **.
