[Rockhounds] Vast 'pumice raft' found drifting through Pacific Ocean

[Kreigh Tomaszewski]

A vast "raft" of volcanic rocks stretching over 150 sq km (93 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.
