Vast 'pumice raft' found drifting through Pacific Ocean
A vast "raft" of volcanic rocks stretching over 150 sq km (58 sq miles) is drifting through the Pacific Ocean, scientists say.
The sea of pumice - the size of 20,000 football fields - was first reported by Australian sailors earlier this month.
Experts say the mass likely came from an underwater volcano near Tonga which erupted around 7 August according to satellite images.
...
"At the moment there are more than a trillion pieces of pumice all floating together, but over time it will break up and disperse across the area," he said. The pumice is currently drifting westwards towards Fiji, and is likely to pass New Caledonia and Vanuatu. It has also been forecast to reach Australia.
