When Did the Last Volcano Erupt?

There are still active volcanos erupting today. In Hawaii you can take tours to see the lava and the eruptions. It is actually big business there with helicopter tours and going at sunset. Guatemala City also has active volcanos right outside the city. When visiting you can see the smoke coming out of the top of the volcano. These are just a couple of examples of volcanos that are still active. There are also volcanos under the water in the ocean that are constantly erupting building new islands.
