Overflight of Pu‘u ‘Ō‘ō

This movie shows views from today's overflight of the vents on the lower west flank of Pu‘u ‘Ō‘ō. There are several vents, topped by spatter cones, that are feeding narrow, fast-moving flows that feed into a broad area of ponded lava.

Lava Lake Within Halema`uma`u Vent

This Quicktime video shows recent activity at the lava lake deep within the Halema‘uma‘u vent cavity. Spattering can be seen in the northwest corner (upper left) and a steady stream of lava, coming from an unseen source towards the southeast, is in the lower right. For scale, the lava lake is about 150 meters (164 yards) wide here. The lava stream plunges into the lava

Spattering Vents

This Quicktime movie shows views of the numerous spattering vents during today's overflight. Spattering at each source is creating spatter cones and ramparts, and the lava issuing from the individual vents is creating a series of narrow streams which join to feed a broader flow channel.

Lava Flow From Pu‘u ‘Ō‘ō

Video showing the main lava stream on the lower east flank of Pu‘u ‘Ō‘ō. This stream carries most of the lava—the rest splits off to the south (to the left) and flows behind the mounds at upper left. The previous video shows the section of the stream visible at upper right. The lava stream here is about 4 m (13 ft) across, 2 m (7 ft) deep, and is moving at speed of about 3

Lava Stream Level Rise Seen Through "Kelly's" Skylight

(Aug 19, 2006, 00:00:33 to 01:40:33) To document changes in the lava stream level within the PKK lava tube, a time-lapse camera was placed at the edge of the informally named "Kelly's" skylight. The camera recorded several abrupt and short-lived increases in lava stream level that eventually sealed the skylight shut. This movie shows a brief increases in lava level of

Time-Lapse of Lava Lake Drop at Pu`u `Ō`ō

This Quicktime movie shows a timelapse sequence taken from the webcam on Pu‘u ‘Ō‘ō's north rim. The movie starts just after noon on August 3, with the typical westward flow of lava within the perched lava lake. Just after 2pm, breakouts start on the flank of the perched lava lake and the lake begins to drop. Remarkably, while the lake drops the circulation is maintained,

Time-Lapse From Thermal Camera at Pu`u `Ō`ō

This Quicktime movie shows a timelapse sequence taken from a thermal camera on the south rim of Pu‘u ‘Ō‘ō, beginning just before noon on August 3. Just after 2pm, the lava lake and surrounding floor abruptly drop. As the lava lake drops, solidified portions of the crater floor slide into the fluid lava. By the end of the sequence, the floor of the crater is composed of

Pu`u `Ō`ō Crater Lava Lake Uplift

This Quicktime movie shows the recent uplift of the lava lake and crater floor in Pu‘u ‘Ō‘ō crater, captured by a thermal camera on the crater rim. The time-lapse movie spans July 9 to today, July 18, and is looped several times. The uplift was continuous between July 9 and 16, but had stalled by the 17th. Throughout this movie, the lava lake activity in the crater was

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

Between June 16 and June 23, 2006, the floor of the pit containing the "Drainhole" vent collapsed, revealing a small lava pond about 12 meters across. Gas pistons continued to occur but were much larger, as is evident when comparing this movie to the others with the same title. The images that make up this movie were acquired by a time-lapse camera positioned on the
