Witnessing the birth of a volcanic island is incredibly rare, but thanks to satellite images, researchers from the King Abdullah University of Science and Technology in Thuwal, Saudi Arabia, retraced the formation of two islands in the Red Sea.
The new islands, called Sholan and Jadid, formed where two tectonic plates pull apart at a rate of about 6 millimeters a year. Magma burst through cracks in Earth’s crust during weeks-long eruptions, piling up rock and creating the new isles, one in 2011–2012 and the other in 2013. The larger island, Jadid, is about one-fifth the size of New York’s Central Park, the researchers report online May 26 in Nature Communications. Anyone wanting to take advantage of the new
