After Dark in the Park - Volcanos National Park

Looking for Lava in all the Wrong Places—and Finding it in Some. Most eruptions and intrusions at Kīlauea take place within the summit caldera or the two rift zones. Some, however, occur elsewhere or have trends not readily explainable by this standard model.

HVO geologist Don Swanson elaborates on this theme in a partly factual, partly speculative, broadly based alternative view of Kīlauea. Part of Hawai‘i Volcanoes’ ongoing After Dark in the Park series. Free.
