Like a toy rocket. The secret of eruption of a strange active in Hawaii volcano is revealed

In a new study, scientists have finally found a strange behavior of the volcano, which erupts in 2018 12 times. Kilauea is an active volcano located in the Hawaiian Volcanic National Park on the Great Island. In 2018, there were 12 eruptions in total, and each of them operated on the same scenario - lava was erupted from the crater like a children's toy rocket, writes ABC News. The Hawaiian volcano is considered one of the most active volcanoes around the world.

According to a geologist from Stanford University and the leading author of a new study by Josh Krozier, the unusual behavior of the eruption probably contributed to the severity of the lava flow, which destroyed more than 600 real estate objects.

The eruptions, which sometimes reached more than 9 meters in height, seemed atypical, since explosive eruptions usually occur due to the lifting of molten rock, magma, or the expansion of steam from magma that heats groundwater. However, the 2018 eruption was caused by the collapse of the magma tank, which suddenly increased the pressure of gas locked in the fire and led to an explosive eruption.

According to Krozier, they and the team used a set of seismic and geodetic instruments and found that there was a strong and sharp inflating of the entire Earth around the magma tank. At the same time, infrasound measurements that fix low -frequency sounds assume a drop in air pressure. This behavior is really different from similar eruptions caused by groundwater and magma. New data is also expected to explain the formation of hot gas atmospheric loams and particles of rocks erupting the volcano.

It should be noted that such high shelfs are literally a threat to aviation. These are not the first anomalous eruptions of the Hawaiian volcano. Previously, they were registered in the 1920s, when a series of large explosive eruptions started. In 2018, increased explosive activity on the top contributed to a strong magma. Then the bench flooded along the eastern rift zone of the volcano, damaging hundreds of houses on the way to the ocean.

In fact, every time the collapse occurred at the top, it created and lifted explosive loops, increasing the pressure in the magmatic tank, which increased the speed of magma. Scientists have come to the conclusion that such an eruption of the volcano actually corresponds to the mechanism of "children's toy - fire missile". However, it is suggested that such a mechanism is not unique to the Hawaiian volcano.
