From the rim of the caldera in Hawaii Volcanoes National Park you can see the massive eruption of Kīlauea, one of two volcanoes in the park. Glowing red lava shoots high into the air before falling back to the ground. Large white clouds of smoke float upwards, almost like a forest fire. Eruptions are common here.
