A river of lava flows smoothly through a lava field. Another flow, this time rough and jagged, tumbles down a small hill. Another smooth pahoehoe lava flow is shown again. At night, tiny dots of orange are visible at the lava field, like city lights. Through a skylight, a river of lava is flowing. Students on a lava field view a plume of smoke out in the horizon. At night, silhouettes of people are outlined by the orange glow of a lava flow. Explosive eruptions then can be seen, with lava splattering in every direction.
