Resembling bundles of licorice, the gnarled lava on Hawaii's Kilauea volcano is known as pahoehoe. The plaited texture forms when the lava's crust slows or stalls but the material below keeps flowing, stretching the surface. Learn to recognize pahoehoe and other volcanic features at this illustrated glossary from the U.S. Geological Survey (USGS). Photos, drawings, and animations can help users distinguish types of volcanoes, eruptions, and ejected material. The glossary is part of the USGS Volcano Hazards Program Web site, which also offers a primer on dangers from volcanoes, information on historic eruptions, and other facts.
