The Jaggar Museum has tons of information about the volcanic activity occurring on the Big Island which is the home to Mauna Kea, Mauna Loa, Kohala, Hualalai, Kilauea, and Loihi volcanoes.
The friendly and information-packed Rangers at the museum can hardly wait the sun to set and for the caldera to light up because crowds of people come to see the dynamic show
The crater at the Jaggar Museum has been erupting steadily since 2008, and lava is flowing outside of the National Park. They offer a webcam of the caldera at: http://hvo.wr.usgs.gov/cams/panorama.php?cam=KIcam.
