I believe the most recent volcano - is 14 November 2006 at Home Reef, Tonga Island, Tonga.

Pumice rafts originally reported to have been from Metis Shoal are now confirmed to have originated from an island-building eruption of the submarine Home Reef volcano. On 12 August, possibly four days after the beginning of the eruption, a sailor spotted the new island after encountering pumice rafts the previous day. The encounter was written in an on-line journal that described the island as four-peaked. A central crater produced steam plumes and occasional bursts of tephra. Data from the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite showed that sulfur dioxide emissions from the Home Reef area began on 8 August, peaked during 8-9 August, and ceased on 15 August. Based on ASTER satellite imagery from 4 October, the island was an estimated 1 km long with an area of 0.23 square km. The temperature of a small lake on the island was 64.7?C. The island was 0.15 square km, based on ASTER imagery from 12 October. Geologic Summary: Home Reef, a submarine volcano midway between Metis Shoal and Late Island in the central Tonga islands, was first reported active in the mid-19th century, when an ephemeral island formed. An eruption in 1984 produced a 12-km-high eruption plume, copious amounts of floating pumice, and an ephemeral island 500 x 1500 m wide, with cliffs 30-50 m high that enclosed a water-filled crater.

I hope the above is the right answer you are looking for.

There's one here in Hawaii called Lo'ihi- it is a volcano underwater, and the eruptions will make it the next island of Hawaii.

there are thousands of volcanoes all over the place... so the last one would have gone off probably not very long ago, under the sea...

There are some vocanoes, such as Etna, in Sicily which are almost always active. Do you mean the spectacular eruptions?
