The Kilauea volcanic eruption in Hawaii may be the key to unraveling the mechanism of the mysterious volcanic eruption

On 3 May 2018 Hawaii'sKilauea VolcanoErupted, and evacuation instructions were issued for about 1,700 residents near Lay Lani, the island of Hawai'i. This eruption that swallows dozens of houses located 20 kilometers away from the eruption point and is damaging a lot of people, but for scientists it is the key to unraveling the mysterious eruption system There is a possibility.

Hawaii's unstoppable volcano eruption could go on on months or even years, scientists say

In Kilauea volcano occurred in 1983Pu Ooh craterThe eruption activity from 30 years has been continuing for over 30 years, and very active eruption activity continues throughout. Although the eruption of this eruption is said to be a crack initiated by the earthquake activity in the south of the Puu Oh crater and the new crater opened as the beginning, the researchers also can not predict when the lava spill will end about.

Hawaii County Civil Defense Service"It is not a time to tour the Kilauea volcano now," but it seems to be said that it is a perfect survey opportunity for volcano experts. The eruption of this time that the sign of the end can not be seen even after several days from the eruption has made us remind that the Hawaiian Islands were formed by the activity of the volcano.

He is a volcanologist at the State University of New York at BuffaloTracy GregHopefully, by investigating the volcanoes on Earth including Kilauea Volcano, understanding of Mars outside Earth and volcanoes on Venus will deepen. Mr. Greg said that safety is the top priority for volcano investigation, "All data obtained by this Kilauea volcanic eruption is wonderful", he said.

According to one theory, around the 8th century people in Polynesia arrived at the Hawaiian Islands and settled there. Early pioneers saw the Hawaiian islands which were actively repeating volcanic activities more than now, and left behind as a tradition of oral tradition such as how lodged lava solidifies. In recent years, scientists have also investigated the inheritance that remains in the Hawaiian islands and discovered many stories that correspond to the earthquake activity that was supposed to have occurred in the past. According to Mr. Greg, however, the survey of volcanic activity in the Hawaiian islands still has a lot of dependence on the data that began to be counted by Westerners 240 years ago. In modern times it was installed near Mount KilaueaVolcano observatoryIt monitors the lava where magma and magma in the ground appeared on the surface 24 hours a day.

The mechanism that causes volcanic eruptions is deep inside the Earth and can not be observed directly. Scientists are trying to unravel the mechanism of volcanic eruption based on observable information related to the volcanic activity such as the amount of magma that exists in the ground, the appearance of the crater, and the earthquake. "This is like a kind of cryptosystem, but we have not yet unraveled this cipher," Greg said.

The eruption activity currently occurring at Kilauea volcano is to provide large clues to volcanologists. The flowing lava eventually solidifies and remains as igneous rock. By analyzing how the magma by the volcanic activity moves based on this igneous rock and gathering data on the eruption activity, we will accurately determine the timing of the eruption and the target of evacuation instructions in the future I can do it. Even in this eruption, the act of returning to the house of residents and collecting the necessary things is not prohibited, and it seems that many residents are returning their belongings to their homes. If the prediction of the volcanic activity becomes accurate, it is said that people will be able to evacuate more smoothly, safely and comfortably.

People who once lived in the Hawaiian Islands said that due to accumulated knowledge over the years, they did not set up residences where they are likely to suffer from the eruption. However, Mr. Greg said, "However, knowledge and respect for nature is decreasing over time.We can not control the volcanic activity itself, but respecting those processes and coexisting It is possible to learn a lot from the eruption this time.
