An underwater volcanic eruption on Oct. 30 has birthed a new island in the Pacific after the explosion flung huge chunks of rock into a pile off the coast of Japan's Iwo Jima island.
"Floating pumice and discolored water occur from the entire periphery of the island, suggesting that magma is erupting from this location," researchers wrote in the statement. Rocks on the island formed a concentric pattern, they noted, but there was no sign of a crater on the surface. Underwater, volcanic material gushing from the seabed instantly solidifies. Regular eruptions have caused Iwo Jima to rise by more than 3.3 feet every year, making it one of the fastest-rising caldera volcanoes in the world, according to the statement.
The eruption is ongoing, and the constant addition of volcanic rock to the newly formed island could protect it from fast erosion.
