Spanish authorities have closed a port on Hierro island, ordered ships away from the island's village of La Restinga, and banned aircraft from flying over the island's southern tip, according to the AFP news service.

The Atlantic turns lime green as lava and gas billow from an underwater volcano off the coast of Hierro island on Monday 17th.

About 10,000 earthquakes have hit Hierro, the smallest of the Canary Islands, since July 19-a sign of the volcano's rising magma, according to the European Pressphoto news agency.
