The Hawaiian Volcano Observatory has two panoramic volcano cams that you can view to watch the current activity at two volcanoes on the big island of Hawaii: Mauna Loa and Kilauea. Mauna Loa is the world’s biggest volcano, by the way. You can also watch some pretty cool time lapse volcano movies on their site as well.
