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.

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.

On February 9, 2005, an eruptive surge at Pu'u 'O'o resulted in episodic spattering and fountaining from the MLK vent, on the southwestern flank of the Pu'u 'O'o cone. The main cone active during this event was 6-7 meters (20-23 feet) high. This suggests that fountain heights reached about 10 meters (33 feet).

At 11:10 in the morning on November 28, 2005, the lava delta at the East Lae'apuki ocean entry, on Hawai'i's southeastern coast, began to collapse into the ocean. This was not a catastrophic failure with the entire 34-acre delta going at once, but instead occurred in a piece-meal fashion over a period of just less than 5 hours.

After the collapse of the main spatter cone at the Martin Luther King (MLK) vent on May 2, 2005, a small lava pond was visible within the new pit. Over the following weeks, the level of the lava pond often changed abruptly, resulting in overflows and spattering along the edge of the pond.

During Spring 2005, activity at the Martin Luther King (MLK) vent, an eruptive vent on the southwestern flank of the Pu'u 'O'o cone, changed from a period of construction to one of destruction. This was highlighted by the collapse of the main MLK spatter cone.

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.

On February 9, 2005, an eruptive surge at Pu'u 'O'o resulted in episodic spattering and fountaining from the MLK vent, on the southwestern flank of the Pu'u 'O'o cone. The main cone active during this event was 6-7 meters (20-23 feet) high. This suggests that fountain heights reached about 10 meters (33 feet).

At 11:10 in the morning on November 28, 2005, the lava delta at the East Lae'apuki ocean entry, on Hawai'i's southeastern coast, began to collapse into the ocean. This was not a catastrophic failure with the entire 34-acre delta going at once, but instead occurred in a piece-meal fashion over a period of just less than 5 hours.

After the collapse of the main spatter cone at the Martin Luther King (MLK) vent on May 2, 2005, a small lava pond was visible within the new pit. Over the following weeks, the level of the lava pond often changed abruptly, resulting in overflows and spattering along the edge of the pond.

During Spring 2005, activity at the Martin Luther King (MLK) vent, an eruptive vent on the southwestern flank of the Pu'u 'O'o cone, changed from a period of construction to one of destruction. This was highlighted by the collapse of the main MLK spatter cone.

A time lapse camera was poised on the southern flank of Pu'u 'O'o cone from early 2004 through mid-2007. This location overlooked the Martin Luther King (MLK) vent and provided a distant view of the top of the Prince Kuhio Kalanianaole (PKK) tube system—the lava tube system active at Pu'u 'O'o from 2004 to 2007.

Late 2003 through early 2004 marked a period of heightened eruptive activity at Pu'u 'O'o, on Kilauea Volcano's east rift zone, with lava frequently spilling from vents within the Pu'u 'O'o crater.

Channeled cascade on Paliuli. Other videos on this day focus on front of this cascade. Wind noise in this and other clips is obvious, but listen for sounds of pieces of crust scraping against one another or across ground. For scale, flow front in all clips is 1-1.5 m high.
