I had intended adding video of my helicopter ride over Hawaii. It showed lava flowing into the ocean as well as a view into a caldera at the lava below. Having had my trasnfer device break down, I though I would add some You Tube links of volcanic activity if it's okay for you all to view....

National Geographic also has a short video of their favourite photos of volcanic activity. There is an ad at the beginning.

I hope you all have had fun learning about volcanoes.
