Nov 30, 2022 · There are two different kinds of solidified lava you can encounter on the Big Island: pāhoehoe (pronounced ‘paw hoey hoey’) and ʻaʻā (pronounced ‘ah ah’). The surface of aʻā lava is sharp, rough, and ‘clinkery’, while Pāhoehoe …

Oct 26, 2022 · When you see lava flow or walk on old lava, the two types of flows are pahoehoe and a’a. Pahoehoe (meaning “smooth lava in Hawaiian) is smooth, undulating, or ropey. A’a is rough, rubbly, and often sharp.

Oct 31, 1997 · The lava is more like foam, and the pahoehoe that forms when the lava cools is very "shelly"; so-called because walking on it is like walking on large egg shells. The lava then tends to form channels that carry the fluid lava away from the vent, thereby beginning a lava flow.

Pahoehoe lava flows are characterized by ropy, billowy, bulbous textures, whether on the surface or on the floor of a cave. It is a Hawaiian word that literally means “smooth.” It is the type of flow most likely to produce lava tubes.

May 27, 1999 · The two main types of lava, pāhoehoe and ‘a‘ā, differ in various properties, such as crystal and gas bubble content, as well as having slight differences in temperature. These properties, along with the steepness of the underlying slope, determine the ease with which a …

Jul 28, 2023 · Pahoehoe is a lava flow with a smooth, ropy, or hummocky continuous surface. Get types, characteristics, how it forms, and transition to aa.

Cross-section of a pahoehoe flow exposed in a sea cliff. Some of the individual flow units have been outlined in white but you can see many others. Two particularly large ones were probably flowing as small lava tubes; the one labeled 'd' drained out at the end of the eruption and the one labeled 'f' solidified full.

Pahoehoe lava flows are characterized by smooth, gently undulating, or broadly hummocky surfaces. The liquid lava flowing beneath a thin, still-plastic crust drags and wrinkles it into tapestry-like folds and rolls resembling twisted rope.

Witness a breakout of pahoehoe (hot, runny) lava (or helluhraun as it is called in Icelandic) as it overtakes a bar...more. Enjoy this video collage with geology professor Shawn Willsey as he...

May 6, 2010 · Pahoehoe is the second most abundant type of lava flow. Pahoehoe lava is characterized by a smooth, billowy, or ropy surface. Pahoehoe flows tend to be relatively thin, from a few inches to a few feet thick. In map-view the flows tend to be narrow and elongate. Image Credit: Steve Mattox, 1989. (Kilauea)
