Lava Level Change in PKK Tube Skylight (August 19, 2006)
To document changes in the lava stream level within the Prince Kuhio Kalaniana'ole (PKK) lava tube, a time-lapse camera was placed on the brink of a lava tube skylight (an opening in the roof of the lava tube) with a view of the lava. Despite its proximity to high radiant heat from the lava, the camera successfully captured several abrupt and short-lived increases in lava stream level that eventually sealed the skylight shut. This video shows one of these brief increases in lava level.
The images that comprise this video were acquired from the edge of a skylight informally called Kelly's skylight. The image acquisition rate was 1 frame per minute, and the resulting video is played at 10 frames per second.
