Collapse and refilling of Pu‘u ‘Ō‘ō crater

(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). The quiet did not last long, though, and lava began to erupt on the floor of the Pu‘u ‘Ō‘ō crater in early July (Episode 57). After

Refilling of Pu‘u ‘Ō‘ō crater

(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. This movie shows lava erupting from the eastern of the two vents. Lava can be seen occasionally overtopping levees that formed along the edges of the lava lake. The images that

Refilling of Pu‘u ‘Ō‘ō crater

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. The images that make up this movie

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

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

The nearly 12-year-long eruption on Kīlauea's east rift zone took a short vacation this past week. No lavaerupted between Wednesday morning and Thursday afternoon, when lava once again reoccupied the same tube to the western ocean entry at Laeapuki and a small channelized 'a'a flow broke out of the tube in the center of the flow field above Kamoamoa.

Several large surface lava flows from the eruption along Kīlauea's east rift zone occurred this past week. The largest of these flowed down the east side of the flow field between the Kamoamoa flows and those that surrounded Waha'ula several years ago.

The eruption along Kīlauea's East Rift Zone continues with little change since our last report in mid-June. There are still two erupting vents located on the southwest and west flanks of the Pu'u 'O'o cone, which is located about 11 miles east of Kīlauea's summit.
