Dome fountain over Fissure D vent of the Episode 58 eruption

(September 20, 2007, 05:00:03 to 09:00:03) As the Episode 58 lava channel developed, the upper end of the channel crusted over so that lava—extruding from the erupting fissure—flowed through a short tube before entering the channel. A small surge of lava on September 20, 2007, exceeded the carrying capacity of this tube and resulted in a small dome fountain through the tube roof near the head of the lava channel. Fortunately, the fountain was short-lived and quit before the cliff on which the camera stood was overtopped by lava. The images that make up this movie were acquired by a time-lapse camera positioned on a small cliff about 70 meters west of the dome fountain. The trace of Fissure D runs directly beneath the camera. Lava enters the channel to the right and flows toward the left.
