Geological Knowledge-the Scene of Volcanic Eruption
    Many people want to know scene of volcanic eruption. Here are a few real scenes of volcanic eruption.
    In 1943, a farmer in Paricutin, Mexico, found a place in the cornfield where the temperature was high. He often came to this place to rest during work breaks and sometimes had a good night's sleep. The temperature of this soil was so hot for the feet . One day, the farmer found a crack in the ground, and smoke and dust slowly appeared. The crack got bigger and bigger, and the smoke and dust grew more and more, accompanied by noise. He ran away immediately when the situation was bad. Later, a large amount of soil and rock fragments spewed out in the smoke and dust, and hot lava masses spewed out, which gradually piled up into mountains and buried the corn fields. Suddenly, there was a loud noise, red light rushed into the sky, and a large amount of incandescent magma gushed from the ground to open the gap from the side of the mountain bag, like a tongue of fire, rushing everywhere, until 1952. it just is the eruption of the world famous Parikutin volcano. From this volcanic eruption, one can imagine the scenes of Laohei Volcano and Huoshao Volcano in the Wudalianchi volcano group.
    Academician Liu Jiaqi, a well-known volcano expert in China, has inspected many volcanoes in the world and witnessed the eruption many times. When he investigated the eruption of Kilauea volcano on Hawaii Island, he saw that the sea was full of smoke and steam . It turned out that lava from a volcanic eruption was poured into the seawater like rolling molten steel to make the seawater boil, set off huge waves, and condensed into rocks and exposed to the surface of the water to become land. When night fell, the central eruption formed a huge fire ball that reflected half of the sky, and the splashing sparks were more gorgeous than the festive fireworks; while the fissure eruption was like a snake and a fire dragon winding and winding, and the dragon flew and danced; What was breathtaking was the vast flow of magma, rushing forward surgingly, forming a sea of fire. The condensed magma on the surface formed lava, which had various shapes such as wave shape, rope shape, and dish shape. This scene resembles the latest lava of the Wudalianchi Volcano Group, but the volcanic landscape of Wudalianchi is richer . While investigating the Reunion volcano in the Indian Ocean, Academician, Liu Jiaqi used an instrument to measure the temperature of the magma and it’s 1050℃ by the magma pool    with the collection freshly solidified lava samples. This is the first time for Chinese to measure the temperature and the sample taken from the erupting crater . Currently, there is no volcano that is erupting in our country, but the actual scene of volcanic eruption can be seen from the above-mentioned examples of foreign volcanic eruptions.
