His name is Niijima, and was given a nickname “Neverland”. We’re talking about a nice little island south of Iwo Jima, in Japan, after the eruption of an underwater volcano. The eruption dates back to last October 21, when the underwater volcano began to erupt, creating the appropriate island in the span of just a week without taking damage.

The site of the eruption, 1,200 kilometers south of Tokyo, is known for some undersea volcanic activity, it is part of the Ogasawara island chain in the western Pacific.

An area characterized by strong volcanic activity

The eruption in recent weeks indicates how volcanic activity in the area has further intensified. The new island could grow and change shape if the eruptions continue, but it could also disappear beneath the waves, as had already happened to those created in the area in 1904, 1914 and 1986, as a direct result of erosion.

Kind of like what happened to us Fedinandea Islandwhich was once born, has been eroded by the constant movement along the Strait of Sicily, one of the windiest seas in the entire Mediterranean.

More and more islands around Japan

From the latest census of geographers, dated early 2023, based on conversion Japan recorded double the number of islands compared to the previously known figures of four archipelagos and approximately 6 thousand islands.

The eruption in recent weeks indicates how volcanic activity in the area has further intensified.

Using digital mapping technology, The National Information Agency has identified a total of 14,125 islands, 7,273 more than previously thought. However, the number will continue to increase in the coming decades.

Attention also remains high in Italy and Indonesia

We know well that volcanic eruptions can change the physical geography of the earth at least locally. What’s happening in Japan actually brings attention to what’s happening in Italy, for example, in the area of ​​the super volcano Campi Flegrei, whose volcanic activity and bradyseism are constantly developing.

It is true that the last significant eruption dates back to 1538 and although it was one of the smallest in the entire history of the Campi Flegrei eruption, it broke a period of calm for approximately 3000 years.

But within a few days it gave rise to the cone of Monte Nuovo, about 130 meters high. In addition to Japan and Italy, where Etna has also been active in recent weeks, it seems that other volcanoes have returned to full activity.

Volcanoes
In Indonesia, since December 4, Mount Marapi on the island of Sumatra, one of 130 active volcanoes in Indonesia, has been erupting, spewing a gray column of ash 3 kilometers high above its 2,891-meter summit.

In Indonesia, Mount Marapi on the island of Sumatra, one of 130 active volcanoes in Indonesia, has been erupting since December 4. a jutting gray column of ash 3 kilometers high beyond its 2,891 meter summit. This activity of his caused, unfortunately, already 23 dead.

Approaching the volcano is prohibited and the eruption warning issued by the Institute of Volcanology of Indonesia is at level 3 on a scale of 4. People working near Mount Marapi are asked to wear goggles, mask and hat. Ash mixed with rain fell on the city of Bukittinggi, Sumatra’s third largest with a population of about 100,000.
