Lava lake draining event during Pu‘u ‘Ō‘ō refilling

(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. The other vent, out of sight to the left, was located on the west-central part of the crater

Long-term Change at MLK Vent

(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. This location overlooked the "Martin Luther King" (MLK) vent, in the foreground (~70 m away), and provided a distant view of the top of the "Prince Kūhiō Kalaniana‘ole" (PKK) tube system—the Episode 55 lava tube system that

Active lava delta on south coast of Kīlauea, Hawai‘i

This lava delta at Lae‘apuki added about 24 hectares (60 acres) of new land to the southeast coast of Kīlauea in 2006, but 6.5 hectares (16 acres) slid into the sea in 2007. White plume marks location of lava entering the sea through a tube whose location is shown by blueish fume in middle right. The delta is covered with many recent surface flows (light gray) that escaped

East Lae‘apuki shatter ring

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). This shatter ring, about 55 meters across and 2.5 meters high, grew between late September and mid-October, 2006, as a result of frequent breakouts from the PKK lava tube just inland from the East Lae‘apuki lava delta, like

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. This movie shows the most spectacular breakout of the series, which fed up to at

Active lava delta, Kīlauea, Hawai‘i

Lava pours over the former sea cliff at East Lae‘apuki onto an active lava delta (left of cliff). The lava broke out from a lava tube just inland of the sea cliff (right of photograph). Lava is also pouring over the cliff within a tube, indicated by the blueish fume rising from cliff behind the lava streams, and entering the ocean as shown by the white laze plume on edge

Lava Breakout from PKK Lava Tube at East Lae‘apuki

(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 lava delta below. The cascade was

Gas Pistons Within Drainhole Vent at Pu‘u ‘Ō‘ō

(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). The shallow accumulation of gas causes the lava surface to rise (the "piston"). Eventually, the gas breaches

Lava Tube Bubble Bursts on the East Lae‘apuki Lava Delta

(May 29, 2006, 10:45:46 to 19:30:49) The interaction of sea water and lava creates a volatile situation (Mattox and Mangan, 1997). When this happens inside the confined space of a lava tube, or a narrow, water-filled crack, the results can be impressive. In this movie, lava bubbles, bursting from the top of the PKK lava tube, put on quite a show for several hours. Some of

Large cracks in active lava delta, Kīlauea

Substantial cracks cutting across a lava delta are clear indication that the delta is subsiding as it grows across the unstable pile of interfingering lava flows and fragments built on the steep submarine slope. The larger cracks on this delta are 1-2 m (3-6 ft) wide. Lava flows spread onto the delta from some of the cracks and then, after solidifying, were cut by renewed

Active lava delta on SE coast of Kīlauea, Hawai‘i

Lava delta at East Lae‘apuki on the southeast coast of Kīlauea Volcano is about 17 hectares (43 acres). The delta extends about 400 m seaward from the sea cliff and is about 850 m long parallel to the shoreline. The steep sea cliff embayment resulted from collapses of earlier deltas; the collapses undermined and took away parts of the cliff. Note similar inactive delta

Shatter Ring on the PKK Lava Tube

(March 20, 2006, 11:30:10 to March 22, 2006, 07:00:16) The flow field feature seen here in profile is a shatter ring. Shatter rings are circular to elliptical volcanic features, typically tens of meters in diameter, that form over active lava tubes (Kauahikaua and others, 2003; Orr, 2011) They are typified by an upraised rim of blocky rubble and a central depression.
