This video shows a sluggish a'a lava flow from the ongoing July 21 fissure eruption east of Pu'u O'o cone. The lava is flowing over a smoother pahoehoe flow from the 1980's. The hardened clinkers are constantly being floated to the front by the liquid interior. Recorded October 6, 2007.

  • Pahoehoe is more interesting then aa cause to be honest nothing is really cool.. but its nice... I wanna see Pahoehoe and aa in Hawaii

    is it nice? should i go or is it a waste of money?

  • Right now (Jan 09) most of the flows are just outside the Hawaii Volcanoes National Park. The county has a viewing area about 1/2 mile away from the ocean entry. You will have a better chance of getting close to lava if you wait until the flows change direction and go back into the park, as the Park Service is less restrictive in allowing access to the area. It can still be many miles away, so you have to be prepared for a long hike and carry lots of water. See the USGS link.

  • i thought hawii could only have pahoehoe lava not a a lava

  • Both types of lava have the same composition, are found in Hawaii and derive their names from the Native Hawaiian language. It takes the form of a'a or pahoehoe (or many variations in between) depending on it's rate of cooling. This in turn depends on its velocity, slope of the terrain, and how turbulent the flow is. For example, an a'a flow coming down a steep hillside can turn into a pahoehoe flow when it reaches a flat area and spreads out over a large area.
