Earth’s New Island in Red Sea is Here to Stay

Posted on January 11, 2012


Earth’s newest island is here to stay.

The island, a mound of lava and ash about 2,000 feet (600 meters) across, piled up during the eruption of an underwater volcano in the Red Sea in mid-December. It was initially suspected of being short-lived — most pileups of volcano debris in water quickly crumble back to the depths — but scientists say this one has solidified nicely.

The new land mass has arisen at the northern edge of the Zubair Islands, a group of 10 islands and shoals off the coast of Yemen that are all thought to have formed during prehistoric volcanic eruptions.

For volcano debris to lay down a permanent address, it must build up faster than waves can erode it; the new island grew at such a rate. According to NASA, “past eruptions in the Zubair Islands were primarily effusive, with relatively runny lava forming thin lava flows. In contrast to the fragmented rock that forms when lava interacts  with water, lava that solidifies on land is tough, so this new island is likely to stick around.”
