Underwater Volcano Erupts, Creating New Island

It’s history coming to life right before our very eyes! An underwater Japanese volcano has recently created a new island. The volcano began to erupt on Frida. And scientists have since confirmed the sighting of a never-before-seen land formation that has resulted from form the eruption.

The new landmass, which was first noticed Sunday by the Japanese Coast Gaurd, is located near the volcanic island of Iwo Jima.

Coast Gaurd Discovers Rare Volcano Phenomonon Near Tokyo

The formation was discovered by the Japanese Coast Guard about 25 miles south of Japan’s Ogasawara island group. The formation is located closest to the island group’s southernmost island, Minami Ioto.

The undersea eruption that created this phenomenon started about 745 miles just south of Tokyo.

The unique land formation occurred when the lava that erupted from the underwater volcano cooled; rising to the sea’s surface.

According to reports, the coast guard crews have also discovered pieces of pumice and volcanic rock floating on the ocean in wide areas.

While this discovery is incredibly exciting, similar events of this nature have proven to be temporary. And experts note, this new formation may not be any different.

In 1904, 1914, and 1986 islands formed in a similar manner. These were discovered shortly after volcanic eruptions. However, the ocean’s waves quickly eroded the formations away. Scientists note that whether or not this island remains for generations to come is dependent on what, exactly, it was that formed the unique addition in the Pacific Ocean.

If the crescent shape landmass was formed by primarily volcanic ash and similar volcanic fragments, scientists report that it is unlikely to last for years to come.

Erosion Could Make Island Temporary

The constant waves atop the new formation will eventually wash it all away.

However, should the underwater volcanic activity that created the unique find continue for some time, the island has a chance of remaining a structure among the sea. The continued volcanic activity is likely to produce lava flows. This hot occurrence will work to solidify much of the ash. This creates a hard shell that is unlikely to erode by the ocean waves. At least, not anytime in the near future.

In 2013, something similar occurred when reported activity from an underwater volcano merged with another existing island, Nishinoshima. The result was an all-new landmass that, before erosion changed the structure, resembled the adorable “Peanuts” pooch, Snoopy.

According to Japan’s meteorological experts, the latest volcanic activity is likely to continue for some time. The Japanese meteorological agency has issued smoke warnings as well as warnings about large ash deposits affecting nearby waters.
