How did the volcano erupt?

Question 1: which is right, volcanic eruption or volcanic eruption? Volcanic eruption

"Outbreak" focuses on violence and is mostly used in volcanic eruptions and major events. "Outbreak" focuses on suddenness, which is mostly used for floods, infectious diseases and so on.

Question 2: How to avoid volcanic eruption? We can't avoid natural disasters, but we can take precautions in advance to minimize the losses.

Let's talk about what to do in case the volcano erupts.

How to escape after volcanic eruption;

1, dealing with lava hazards. Among the hazards of volcanoes, lava flows may pose the least threat to life because people can run out of the route of lava flows.

2, to deal with the harm of spray. If you escape from the vicinity of a volcanic eruption, the hard helmet, motorcyclist's helmet or rider's helmet used by construction workers will give you some protection. In a wider area, escape may not be necessary.

3. Respond to the hazards of volcanic ash. Wearing goggles, a breathing mask or ski goggles can protect your eyes-but sunglasses can't. Cover your mouth and nose with a damp cloth, or use an industrial gas mask if possible. After arriving at the shelter, take off your clothes, thoroughly wash the exposed skin and rinse your eyes with clear water.

4. Respond to the hazards of gas pellets. If there is no solid underground building nearby, the only chance of survival may be to jump into the water; Hold your breath for about half a minute, and the ball will roll over.

Remember: Volcanoes tend to increase in activity before eruption, accompanied by rumbling and steam gas overflowing, and sulfur can be smelled from local rivers. * * * Acid rain, rumbling or plumes of green steam from volcanoes are all warning signals. When driving away, remember that volcanic ash will make the road slippery. Don't take the canyon route, it may become the road that Rajal passes through.

Question 3: Why do volcanoes erupt on the earth where we live? Volcanoes often erupt. Whenever a volcano erupts, hot magma from the crater will flow everywhere, destroying crops and houses. So, why did the volcano erupt?

It turns out that the earth's crust is rock, and the deep place below the crust is magma, which is usually tightly wrapped by the crust. The temperature inside the earth is extremely high, so the temperature of magma is also very high. Magma is circling around in it and can't stay. I always want to find a place to drill outside. Due to the strong movement in some parts of the earth's crust, cracks appear, and some places are relatively thin. When these places are under pressure, magma will erupt from these places, which is called volcanic eruption, or volcanic eruption. The ejected magma condenses when it is cold and accumulates into highlands. This is a volcano. At the top of the mountain, there is a crater that spews out magma. Some volcanoes erupt only once and are called dead volcanoes, while others erupt many times and are called active volcanoes.
