The sea bubbled and boiled, steam rose and rocks spat forth into the air. Slowly a mound began to emerge from the waves, and within days a new island was born. It might sound like something from the book of Genesis, but it is just how the world's newest island emerged from the ocean.
On 9 August 2006, yachts sailing around Tonga reported sightings of a submarine volcanic eruption at Home Reef, south of Late Island. Three days later the crew of the Norwegian yacht Maiken caught sight of an island not found on any nautical chart. Approximately 1.5 kilometres across, it was capped by a huge plume of steam, and the sea for miles around was covered with floating rafts of pumice spewed out by the eruption.

August 2006 brought two new things to the Tonga Islands in the South Pacific. One was a raft of lightweight, frothy volcanic rock—pumice—floating on the ocean surface. The other was a new island emerging out of the water.

According to the Pacific Tsunami Warning Centre a tsunami was generated by a strong earthquake that struck under the Pacific Ocean floor near Samoa on Thursday.

"Sea level readings indicate a tsunami was generated. It may have been destructive along coasts near the earthquake epicentre".

But there was no immediate report of damage.
