Mount St. Helens (May 18, 1980) in southwest Washington state is the most recent volcanic eruption in the continental US. In Hawaii, Mauna Loa has erupted more recently (1984) and Mount Kilauea has continued to erupt since 1993.

Mount Vesuvius which last erupted in 1944.
There are actually two ways of classifying volcanoes. The first one is by activity. If it has erupted recently and most likely will, then it's active. If it hasn't erupted recently but still has a magma chamber, it's considered dormant. If it will never erupt again and has no source of magma, then it's extinct. The second one is by the shape. Usually they are put into three main categories. The shortest, but wide volcano is called the shield volcano. These volcanoes are made from heavy and unpressurized lava. Some can be found in Hawaii. A less wide, but much taller volcano is called the cinder cone volcano. This volcano is made from lava building up upon the volcano. The tallest of the volcanoes are called composite volcanoes or stratovolcanoes. They are much bigger than the others and they are considered the most dangerous not just because of the lava, but especially because of the ash they eject.
The Akutan volcano is a stratovolcano on Akutan Island in the east-central Aleutian Islands of southwest Alaska. In 1992 the volcano erupted with just ash and steam in 1992. There was no damage, just plumes of ash and smoke.
volcano name= ETNA location= ITALY active time= 3500 YEARS
Sufrie hills has recently erupted on February 11, 2010 and blew vast clods of ash towards other islands.
The most eruptive volcano is Etna in Italy. It has erupted continually for over 3500 years.
Kilauea volcano
krakatoa/krakatue

No, not by any definition. If you define the "youngest volcano" by "most recently erupted", then that honor goes to Kilauea, which has been erupting non-stop since 1983. Mount St. Helens last "erupted" in early 2008 when steam escaped from a fracture in the lava dome.
well, so far... in the internet, its say... mt helens i think... better to check on google...there is one that has happened in the middle of the sea

The volcano erupted in Iceland but the ash from the volcano covered most of Europe and Asia.
