Last week, we told you about a 7,500-square-mile raft of pumice discovered floating in the Pacific Ocean, but more recent observations by NASA reveal that chunks of the volcanic rock have since spread over an area of 100,000 square miles. So people are starting to wonder: What will become of the pumice?
Australian Naval officer Tim Oscar called the massive chunk of volcanic rock pictured up top "the weirdest thing [he'd] seen in 18 years at sea." Now, NASA satellite images have revealed the source of the floating raft: a mysterious undersea volcano known as the Havre Seamount.
When an undersea volcano erupted this past May near Samoa, researchers captured video of the blast. Now they've released the footage, giving the rest of the world its first look at the deepest underwater eruption ever caught on film.
