Virtual Lava Tube

Lava tubes are cave formations found where volcanoes generate surface flows in the western United States, Japan, Italy, Australia, and other areas. They vary in size and complexity, from short, straight formations to multi-leveled labyrinths that extend for miles. The largest and most extensive lava tubes discovered to date are in Hawaii, where lava flows can travel more than 80 kilometers (50 miles) from their source. This interactive feature offers a visual tour of lava tubes and various features formed by flowing, splashing, or dripping lava. Viewers can click on a cross-section of a lava tube and see photos and explanations for the formation of the features. Educational levels: Middle school, High school, Intermediate elementary
