What is the air like for the re eruption of the Hawaiian volcano?

On May 23, local time, the Kilauea volcano on the island of Hawaii in the United States erupted several times, and magma flowed into the sea, and the resulting smoke clouds covered the entire island. On the morning of the 23rd, Kilauea erupted two more times. Thick ash rising from the crater can be seen.

The first eruption of the day was reported to have a maximum of 2,438 meters of ash, and the second eruption to a maximum of 1,524 meters.

The Hawaii National Guard said a geothermal power plant near the volcano was not affected. The magma eventually flows into the sea. The red-hot magma met the sea, rising a toxic cloud of smoke that enveloped the entire island.

The continued eruption of Kilauea has also caused the concentration of toxic sulphur dioxide gas in the air to skyrocket. According to the U.S. Geological Survey, the crater is emitting 15,000 tons of sulfur dioxide gas per day and counting. A number of local schools have been closed, and face shields have been distributed to residents in the affected areas.

Since the 3rd of this month, the activity of the Kilauea volcano has intensified, and magma has continued to erupt, and the number of eruptions has now exceeded 20, forcing thousands of residents and tourists to evacuate, and dozens of buildings have been destroyed.

Now you have basically no problem traveling to the island of Hawaii, the air is not affected, but now after the eruption, the red magma is gone, only the smoke, but the lucky drop may still be visible.

The Hawaiian Islands themselves are volcanic islands, and the area where they are located is a volcanic zone in the Pacific Ocean, located on the crustal fault zone of the Pacific bottom, and the Hawaiian Islands are all formed by magma, and there are active volcanoes until now. The following is a compilation of volcanic formations and contents in Hawaii, so you can refer to them.

1 Causes of the formation of volcanoes in Hawaii.

The formation of volcanoes is a series of physicochemical processes. The main thing is that the large amount of radioactive material present in the interior of the earth, decays in its natural state, producing a large amount of heat. Once this magma breaks through the earth's crust and erupts out of the ground, volcanoes are formed.

Causes of the Hawaii Volcano: Hawaii is in a subduction zone of plate movement and plate pure swimming. Most ** and volcanoes are caused by plate compression.

For example, if the oceanic plate and the continental plate collide together, the oceanic crust is relatively heavy, so it squeezes under the continental crust. As a result of this squeezing, a large amount of heat energy is released, and many of the rocks in the mantle melt into magma, and the liquid rises upward. When the upward pressure accumulates to a certain extent, it erupts on the surface of the earth's crust.

Hawaii is the only archipelago state in the United States, consisting of 132 islands in the middle of the Pacific Ocean. The Hawaiian archipelago was formed by volcanic eruptions and includes 8 large islands and 124 small islands that stretch for 2,450 kilometers to form a crescent-shaped island chain. Hawaii Island is the largest island with two active volcanoes.

2Introduction to Hawaiian Volcanoes.

Characteristics of Hawaiian volcanoes.

The main volcanoes on the island of Hawaii are two active volcanoes, Mona Loa and Kilauea. The biggest feature of Hawaiian volcanoes is highly fluid basalt lava, not **-style volcanic eruptions.

Molten magma spills out of the ground during a volcanic eruption in Hawaii, but there is no ** phenomenon, and there is very little gas and pyroclastic eruption. Before lava erupts, magma rises from the lower part of the earth's crust until the surface overflows from the crater. Sometimes, a thin crust forms on the surface of the lava, which then cracks open and the lava flows out again.

Known as the "long-term volcano" in Hawaii, Mount Mauna Loa is located in Hawaii Volcanoes National Park, the world's most active volcano and the world's highest island active volcano. And compared to other types of active volcanoes, Mauna Loa is older and larger. The last time Mauna Loa erupted was in 1984, when the erupted lava poured down about 27 kilometers.

At 4,169 kilometers above sea level and about 75,000 cubic kilometers in volume, Mona Loa is the largest mountain in the world. Arriving at the Mauna Loa Crater, you can see magma of various shapes as well as cinder cones of various sizes.

When red-hot lava buries plants and shrubs, the burning plants produce methane, a colorless gas that burns blue and, according to the USGS, seeps into the voids below the surface — in this case, a crack in Kahukai Street in the Juhui Hood neighborhood of the Leilani estate. According to the U.S. Geological Survey, the heated methane may have **, but when it was ignited Tuesday night, its blue flame simply burned from a crack in the highway a few feet away from the lava.

Very dramatic. Jim Kauahikaua, a scientist with the U.S. Geological Survey, told The Associated Press. Kauahikaua said it was the second time in his career that he had seen blue flames during a volcanic eruption, and these eerie blue flames were actually burning methane.

U.S. Geological Survey) About 2,000 people have been evacuated from the Leilani estate and adjacent areas since the eruption began in early May. More than 20 cracks have been opened, injecting lava and volcanic gases such as sulphur dioxide into the area. "kdspe" "kdsps" One person was even hit in the leg by a "lava bomb", and a vivi blue section of lava lava erupted from the volcano and lived to tell the story.

The eruption destroyed about 50 buildings, including about 24 houses.

The pink and red areas show the flow of lava during this eruption. Original article on life sciences (USGS).

It's because after the lava flow was controlled at the top of the mountain, there was a real eruption. The world's largest volcano, Hawaii, in the United States, began to erupt, and if it did, it would certainly be a big blow. In addition, if the area of the eruption is relatively large, there is a high risk that it will affect the road.

And this height has a vertical height of 10,203 meters, and the area can be as high as 5,120 square kilometers.

The lava flow is contained at the top of the mountain, and the eruption occurs directly

When the lava flow is contained at the top of the mountain, it will erupt. A volcano in Hawaii is currently erupting, and the lava flow has reached the highway, and the eruption is expected to be particularly uncomfortable. And there is a possibility of harming some, so the damage is still relatively large this year, and the sudden development of the world's largest active volcano feels quite dangerous.

The volcano began to erupt, and it must have been no small blow

When the volcano starts to erupt, the impact is still relatively large, and this is the largest active volcano in the world, which feels quite dangerous. Volcanic eruptions are a strange phenomenon, so these lava will also be released directly in the crater, because there are still a lot of volatile cavities in it, so it will erupt directly. In this case, if the area of the recipe is smaller, it is fine, but if the eruption area is larger, it is too dangerous.

The largest active volcano in the world, the influence is relatively large

Usually when a volcano erupts, it is because the lava cannot withstand the pressure, so it will eject out of the surface. If he is so hot, he will release it after the previous level, and the energy released will also erupt directly, which feels quite scary. When the volcano erupts, try to stay away as much as possible, otherwise it may affect the body and the eyes may overflow, which is really dangerous.

Volcanic eruptions are caused by the formation of mantle convection or mantle plumes inside the mantle due to uneven temperature and density inside the mantle. When a hot substance rises to the shallow part of the earth, partial melting occurs due to a decrease in pressure. Under the action of external forces, these molten materials come together and form magma sacs in the shallow part of the earth.

When the pressure of the magma sac is greater than the pressure of the formation, the magma will break through the earth's crust along faults or weak spots, causing volcanic eruptions.

The eruption of the volcano is magma, which is the main component of the Fengshan volcano. Volcanic eruptions are when magma flows out directly after a certain amount of occupancy, and this magma can be blown into the thin strands of hair by the wind. Historically, every eruption has lasted for several weeks, so this is probably the case this time.

Therefore, this magma is the ejecta of some volcanoes, and it is quite scary to blow a large amount of liquid to the surface through this.

Volcanoes erupt with magma, and magma is the main body

Many people are interested in what the volcano erupts, in fact, this thing is magma, mainly because the energy in it is relatively sufficient, this energy comes from the interior of the earth, and when the earth can't bear it, all the energy will erupt. That is, what we call this magma erupts from this, and with the surrounding covering, the magma can burst out directly, and then form a liquid liquid.

In fact, it is magma, which flows slowly

Others don't know what the volcano erupts is, but it's actually magma, that is, it looks red, and that one is like fire, and it will burn if it is poured directly on the ground. Lianjiang is amazing, it is a unique substance, and volcanic eruptions are also very magical, which is also the result of the continuous movement of the earth's crust. Maybe it's because the interior of the earth is hot, and then to a certain extent, it will show completely different content.

By blowing to the surface, a large amount of molten slurry is released

I think that eruptions are a more professional phenomenon, but also a strange story, which is caused by the movement of the earth's crust, and volcanic eruptions can occur when the heat in the earth's interior is relatively high. The magma emitted by a volcano erupts through internal energy, triggering its internal release. When it can't bear it, this volcano will erupt, and you must stay away from it, which is particularly dangerous.

The main reason for the outbreak of the fire is that there are some soft processes composed of plastic materials in the dispersal of the mantle, which is the most important source of magma. Volcanoes release energy that emits this energy** into the Earth's interior.

The air emitted by volcanic eruptions contains many materials, including igneous gas, lava, carbon dioxide, volcanic rock debris, volcanic ash, and many other materials.

The cause of volcanic eruptions is the movement of the earth's crustal plates, resulting in some faults and fissures. Magma carves a path through the weak crust and erupts to the surface, cooling down to become a volcano.
