Massive Underwater Volcano Eruption Creates New Island

A new island has been formed in the Pacific Ocean off the coast of Japan due to volcanic eruptions from an underwater volcano. The islet is located in the Ogasawara island chain, more than 1,000 kilometers south of Tokyo. According to the Maritime Self-Defence Force’s air base on Iwoto Island, previously known as Iwojima Island, the new isle emerged on November 1. The personnel on Iwojima heard a loud noise and saw sand being sent high in the air as the new island was created.

The Japan Meteorological Agency (JMA) detected tremors on Iwoto Island every few minutes since October 21, after which the volcanic eruptions were reported. The new island was formed near the crater of the undersea volcano. A JMA official stated that it is possible that a large amount of rocks and stones ejected from the crater on the seafloor accumulated and created the islet.

New islands have emerged in the region in the past, but all of them submerged within months due to harsh sea conditions. This islet is the first in the region since 1986. Volcanic eruptions are continuing, and officials have warned of smoke and large ash deposits in the region.

Earlier this year, digital mapping led to around 7,000 new islands being discovered around Japan, according to a report in The Guardian. The islands were found after the Geospatial Information Authority of Japan conducted a survey, the first of its kind in 35 years. However, it had no impact on the size of Japan’s territory of 37,000 square kilometers.

The emergence of this new island is a result of the volcanic activity in the region. Researchers are studying the island to understand more about the geological processes that led to its formation. The residents in the region are advised to take necessary precautions due to the continuing volcanic activity, including acidic seawater and gas emissions.
