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 of the 13.8-hectare delta, but instead occurred by piecemeal calving of the front of the delta over a period of just less than 5 hours.

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.

(May 10, 2005, 16:20:29 to 18:30:29) After the collapse of the main spatter cone at the MLK vent (see movies "Spatter cone collapse at the MLK vent"), a small lava pond was visible within the new pit. At times, the level of the lava pond rose abruptly, overflowing the rim of the pit.

(May 2, 2005, 05:30:04 to 07:30:02) During spring 2005, activity at the MLK vent, on the southwestern flank of the Pu‘u ‘Ō‘ō cone, changed from a period of construction to one of destruction. This was highlighted by the collapse of the main MLK spatter cone.

(May 2, 2005, 02:30:28 to 07:30:37) The spatter cone collapse described in the movie below was also recorded by a time-lapse camera on the west flank of the Pu‘u ‘Ō‘ō cone. This camera was located about 70 meters from the MLK vent and recorded two pulses of lava effusion from the vent before collapse.

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.

(February 9, 2005, 18:00:30 to February 10, 2005, 08:00:31) On February 9, 2005, an increase in lava discharge from Pu‘u ‘Ō‘ō, part of a longer term increase in effusion rate (Miklius and others, 2006), resulted in vigorous spattering and low fountaining from the MLK vent.

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.

(March 2, 2004, 11:48:17 to 23:08:42) Late 2003 through early 2004 marked a period of heightened eruptive activity at Pu‘u ‘Ō‘ō (Miklius and others, 2006) on Kīlauea Volcano's east rift zone, with lava frequently spilling from vents within the Pu‘u ‘Ō‘ō crater.

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.

Nearly continuous spattering from west vent of West Gap Pit, and sporadic spatter bursting from tall hornito to left. Heaving pond of lava between camera and vent. Hand-held camera, so a bit shaky. Note especially the symmetrical burst from hornito at about 15 seconds. Noise is reasonable facsimile of the real thing, emphasizing the treble.

Spattering from east vent in West Gap Pit, taken from same place as other video and also hand-held. Note the spatter rampart under construction by the falling spatter. Helicopter noise for first several seconds.

Lava pours out from under crust at front of advancing breakout. See still taken at 0607:33 today.

Lava emerges from under crust along side of breakout on steep slope. Listen to creaking sounds, about halfway through video, as crust flexes and breaks. See still taken at 0610:15 today.

Lava appears from under crust and drops into depression at front of advancing breakout. Width of blob of lava that appears is about 30 cm.

This clip lasts 30 seconds and so is a large file, but it shows such notable dynamics at flow front that it might be worth it to some of you patient ones. The active stream is 50-75 cm wide. Note, early on, how sliding crust plows into lava.

Lava issues from breached tube and quickly disappears over old sea cliff. Note that center of stream stands above margins. See still taken at 0545 today.

Same cascade as in first clip, but viewed more from side to see lava falling down cliff and spreading across surface of lava delta. Similar view to still image taken at 0548 today.

Surging cascade on steep cliff face. Note that surges override part of cascade next to cliff, which is slowed by friction with the cliff.

Lava in channeled breakout from nearby tumulus flowing rapidly down steep slope before spreading out on flat ground. Same channel as shown in last two stills for today. Width of channel, about 2 m.
