Dome Fountain Over Fissure D of the July 21, 2007 Eruption (September 20, 2007)

Just after midnight on July 21, 2007, a new fissure eruption broke out on the eastern flank of the Pu'u 'O'o cone (http://hvo.wr.usgs.gov/pressreleases/pr07_21_07.html). Activity quickly focused on the easternmost fissure—Fissure D—and lava began flowing to the northeast (http://hvo.wr.usgs.gov/archive/2007_09_08.html) eventually creating a lava channel perched above the surrounding terrain. A small surge of lava through the system on September 20, 2007 resulted in a small dome fountain over Fissure D at the head of the perched lava channel. Fortunately, the fountain was short-lived and quit before the cliff on which the camera stood was overtopped.

The images that comprise this video were acquired by a time-lapse camera positioned on a small cliff about 70 meters (230 feet) west of the dome fountain. The image acquisition rate was 1 frame every two minutes, and the resulting video is played at 10 frames per second.
