Looking down the channel of Fissure D

(June 10 to July 25, 2007) During June 17–19, 2007, an intrusion into Kīlauea's upper east rift zone (Episode 56) led to the cessation of eruptive activity at Pu‘u ‘Ō‘ō and the collapse of the Pu‘u ‘Ō‘ō crater floor (Poland and others, 2008).

(July 13, 2007, 14:00:30 to 21:00:36) Episode 57 was driven by the eruption of lava from two vents—one on the west-central part of the crater floor and the other on the eastern side of the crater.

On June 17-19, 2007, and intrusion into Kilauea's upper east rift zone led to the cessation of eruptive activity at Pu'u 'O'o and the collapse of the Pu'u 'O'o crater floor.

The refilling of Pu‘u ‘Ō‘ō during Episode 57 was driven by the eruption of lava from two vents—one on the west-central part of the crater floor (to the right) and the other on the eastern side of the crater (to the left). This movie shows the competing interaction between flows from these two vents for a period of several hours on July 8.

(July 5, 2007, 23:00:06 to July 6, 2007, 09:00:06) With the resumption of eruptive activity at Pu‘u ‘Ō‘ō on July 1, 2007 (Episode 57), a lava lake, fed by two vents, quickly began to form within the Pu‘u ‘Ō‘ō crater. The vent seen here was located on the eastern side of the crater.

(April 2, 2004, to October 28, 2006) A time-lapse camera was poised on the southwestern flank of Pu‘u ‘Ō‘ō cone from early 2004 through mid-2007.

October 16 , 2006, 06:20:23 to 08:00:22) This is another movie showing a shatter ring in action (see "Shatter ring on the PKK lava tube", 03-20-06).

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.

(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.

Between the morning of September 20, 2006 and the evening of September 22, 2006, there were 10 separate breakouts from the East Lae`apuki tube about 50 meters (165 feet) inland from the older sea cliff behind the East Lae'apuki lava delta.

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 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.

(June 24, 2006, 19:00:53 to June 25, 2006, 01:00:55) After sunset on June 24, 2006, lava burst from the PKK lava tube about 50 meters inland from the older sea cliff bounding the inboard edge of the East Lae‘apuki lava delta. Lava reached the sea cliff and began cascading over it in less than a minute, and it spread quickly across the l

After sunset on June 24, 2006, lava burst from the East Lae'apuki lava tube about 50 meters (165 feet) inland from the older sea cliff behind the East Lae'apuki lava delta. Lava reached and began cascading over the sea cliff within a minute, and quickly spread across the lava delta below.

(June 2, 2006, 18:30:02 to June 3, 2006, 02:00:03) Gas-pistoning is an interesting phenomenon seen at Kīlauea and some other basalticvolcanoes. It is caused by the accumulation of gas near the top of the lava column within a volcanic vent (Swanson and others, 1979).
