Since 2022, there has been too much news about volcanic eruptions, starting with the violent eruption of The Tonga Volcano, which triggered a multinational tsunami around the world. Then came another piece of news about The "fooling around" Mount Fuji in Japan, what is the situation? Are global volcanoes also active in 2022?
Of course, the monitoring data of mt. Fuji in Japan is indeed a bit surprising, after all, this change is very strong, so how strong is it?
That is, according to Korean media reports, through the monitoring of Mt. Fuji, the Japanese people are worried that Mt. Fuji is about to erupt, and it seems that the change has really occurred, and there has been a sharp increase in the number of "craters". According to monitoring data, the number of fire vents in Mount Fuji, Japan, has increased by nearly 6 times.
Therefore, at one time, many people worried that Mount Fuji in Japan would erupt. Mt. Fuji, which has been dormant for more than 300 years, may not be stable. But is it really unstable?
In fact, it is not, although there is an active situation in Japan's Mount Fuji, but Japan's Mount Fuji is an active volcano, no matter how active it is, it can be explained that it is also a common thing to be in a relatively "stable" state all year round, and we cannot be sure that the volcano is about to erupt according to some changes in Japan's Mount Fuji, which is not a thing at all.
Mt. Fuji is an "active volcano" that can erupt on a large scale at any time. So, it's not that its crater increases and there will be an eruption, but this sign may indicate a problem, that is, the internal activity has indeed become much stronger.
However, in any case, the eruption of Mt. Fuji in Japan is not a good thing for us, after all, it can have a catastrophic impact.
As you should remember, the large-scale eruption of the Tonga volcano, volcanic ash, gas, water vapor into the sky to form a huge cloud, erupted to a height of 20 kilometers, the United States, Japan and other countries also appeared tsunami warning. Although it will ultimately have little impact on other countries, many say that the eruption of Tonga's volcano may lead to a "summerless year".
Mount Fuji in Japan can be said to be a worldwide "supervolcano", which may be much stronger than the Tonga volcano, and once there is a large-scale eruption, it may bring about great changes in the global climate. Of course, the Tonga volcano has caused the problem of "summerless years", which is basically certainly not.
And this is not, after the two volcanic eruptions, the volcanoes in the United States have come again, and they are afraid of erupting? What's going on here? What has changed in the volcano?
For many people, when it comes to volcanoes in the United States, it is undoubtedly the "Yellowstone Supervolcano" that is the most hotly discussed, but this time it is not the "Yellowstone Supervolcano" in the United States, but the "Three Sister Volcanoes" in Oregon, which is not as powerful as the Yellowstone Supervolcano in the United States, but it is also one of the most dangerous volcanoes.
According to data monitored by the U.S. Geological Survey Center, data from satellite radar images show that the volcano in the United States has an anomaly, with a constant "uplift" on the ground, with about 0.9 inches or 2.2 centimeters of uplift in an area of 12 miles (20 kilometers) in diameter between the summer of 2020 and August 2021.
Since August 2021, GPS data from a volcano monitoring station near the uplift center has measured at least 0.2 inches (0.5 centimeters) of the uplift.
Moreover, for the entire volcano, uplifts are occurring continuously. Scientists at the U.S. Geological Survey are monitoring this activity as carefully and thoroughly as possible and will continue to monitor the area as long as it continues to gain more insight into the process.
Through the overall time data, in the 25 years from 1995 to 2020, the central area of the volcano rose by about 12 inches or 30 centimeters (equivalent to the height of a 2-liter soda bottle), that is, the central area of the volcano, which rose about 30 centimeters in 25 years.
Could it be that one of america's most dangerous volcanoes, the "Three Sisters Volcano," is about to erupt? Through the available data, the volcano's activity may be due to the uplift caused by the eruption of a small earthquake, and scientists have found small pulse activity accumulated by the magma at about 4 miles (7 kilometers) below the surface through specific analysis.
This could have contributed to the volcano's frequent activity. However, whether it will erupt is uncertain, and while any magma intrusion could eventually lead to a volcanic eruption, there could be detectable, more intense earthquakes, ground motion (deformation) and geochemical changes before the eruption.
Today, we can only continue to observe the phenomenon of uplift, whether it is really a large-scale eruption, this is still unknown. So CVO scientists will be closely monitoring the data in the coming months. We can only say that the activity of this volcano is still happening, but there is no way or ability to be sure that this volcano is really likely to erupt.
Although it is also an active volcano, volcanic activity, like earthquakes, cannot be confirmed.
Finally, the "Three Sisters Volcano" of the South Sister Volcano is the most dangerous, the South Sister Volcano last erupted 2000 years ago, and in 2007, although scientists saw the volcano's uplift zone appear smaller, but it is still very active, which makes the South Sister Volcano one of the most dangerous volcanoes in the United States, known by the United States as a "very high-risk" volcano.
The Middle Sister Volcano and the North Sister Volcano echo it and belong to the same large area, so the three of them are called "Three Sister Volcanoes". So, this is also an "extremely dangerous" volcano.
