Detailed Description

(September 8 to November 30, 2007) Within days of the onset of Episode 58 on July 21, 2008, activity localized on the easternmost eruptive fissure—Fissure D—and channelized lava began flowing to the northeast. Repeated overflows from the channel added slowly to its height, and the channel became perched up to 45 meters above the pre-existing lava surface. The images that make up this movie were captured by a time-lapse camera positioned on the west flank of the Kupaianaha lava shield, about 500 meters from the channel. The erupting vent over Fissure D is the fume source near the left side of the view, and Pu‘u ‘Ō‘ō is the cone in the background behind that. The channel flow direction is from left to right.
