The island of Hunga Tonga Hunga Ha’apai rose from the seabed about 65 kilometer northwest of the Tongan capital Nuku’alofa in late 2014-early 2015.


Scientists initially expected the island, created when vast quantities of rock and dense ash spewed from the Earth’s crust, to wash away within a few months. But NASA said it had proved more resilient than expected, possibly because warm sea water combined with ash during the volcanic explosion to create a concrete-like substance known as “tuff.”


While the island Cheap NCAA Jerseys Online , which initially measured 1 kilometer wide, 2 kilometers long and about 100 meters high, has undergone significant erosion, it is now expected to last anywhere from six to 30 years.


Jim Garvin, the chief scientist at NASA’s Goddard Space Flight Center, said it was a rare chance to study the life cycle of a new island.


He said Mars has many similar volcanic islands that appeared to have been surrounded by water when they were created.


Garvin said such spots may be prime locations to look for evidence of past life because they combined a wet environment with heat from volcanic processes. Examining how life gained a foothold on the Tongan island could help scientists pinpoint where to look for evidence of life on Mars Cheap NCAA Hats China , he said.
