Views: Shatter Ring on PKK Lava Tube (March 20-22, 2006) The flow field feature seen here is called a shatter ring. Shatter rings are circular to elliptical volcanic features, typically tens of meters (yards) in diameter, which form over active lava tubes. They are typified by an upraised rim of blocky rubble and a central depression. Dozens of shatter ri... Shatter Ring on PKK Lava Tube (March 20-22, 2006) ... Location: HI, USA Lava Level Change in PKK Tube Skylight (June 11, 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.
