A new island is forming in the Red Sea. About 60 kilometres (40 miles) from the coast of Yemen, an undersea eruption began in mid-December 2011. The eruption has risen nearly completely above water.
The activity was located on the northern edge of the Zubair Islands. On December 23.
The land surrounding the vent has grown, and is now about 530 by 710 meters (1,700 by 2,300 feet) across.
Once above water, 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 directly with water, lava that solidifies on land is tough, so this new island is likely to stick around.
