Scientists flying over Ka lauea's lower East Rift Zone used a telephoto lens to photograph the surface of the fissure 8 lava channel. Incandescent lava is visible through pieces of darker crust that forms as the flow surface cools. Note the apparent symmetry on either side of the channel center, where lava flows more quickly than it does along the channel margins a visual representation of flow velocity across the channel width. | |
