East Lae'apuki Shatter Ring (October 16, 2006)
The lava-tube 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.

Lava breakout from the PKK lava tube at East Lae‘apuki
(Sept 21, 2006, 18:00:02 to 00:00:05) Between the morning of September 20 and the evening of September 22, 2006, there were 10 separate breakouts from the PKK lava tube. Each originated about 50 meters inland from the older sea cliff bounding the inboard edge of the East Lae‘apuki lava delta.

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.

Gas-Pistoning at Drainhole Vent in Pu'u 'O'o Crater (June 28, 2006)
Gas-pistoning is an interesting phenomenon seen at Kilauea and other volcanoes. It is caused by the accumulation of gas within, or the rise of a gas slug through, a column of lava. In either case, the gas pushes up the overlying lava (the "piston"). Eventually, the gas breaches the surface and escapes, sometimes as a forceful jet of fume and spatter.
