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

Kīlauea Summit Vent Collapse

Movie showing the fourth of five large collapses within Kīlauea's summit vent on the floor of Halema‘uma‘u. The collapse was captured by a Webcam located on the rim of Halema‘uma‘u directly above the erupting vent.

Vigorous boiling of the lava surface in Kīlauea's summit vent

Photo of vigorous boiling of the lava surface in Kīlauea's summit vent following vent wall and rim collapses earlier in the day. The rim of the vent on the floor of Halema‘uma‘u is about 150 m (yards) across. The lava surface is about 100 m (yards) below the rim.

Erupting Vent and Flow (Pu`u `Ō`ō Crater)

A movie of the erupting vent on the east wall of Pu‘u ‘Ō‘ō Crater. The movie begins with a cascade of lava filling the southern opening on the east wall and ends at the spattering source, which is producing the cascading flow.

For more than twenty years, Kīlauea has been erupting almost continuously. In the early years, the eruption alternated between dramatic fountains and periods of repose. For the last 16 years, however, Kīlauea has settled into a stable routine-lava quietly flows out of flank vents on Pu`u `O`o cone into lava tubes, which wind sinuously toward the ocean.

The inflation of Mauna Loa Volcano that started last year appears to be slowing down. From May 2002 until very recently, continuously recording instruments spanning Moku`aweoweo, Mauna Loa's caldera, showed that the summit area was extending and rising, indicating that magma was pressurizing a reservoir beneath the surface.

On January 4, as lava flowed from the Pu`u `O`o cone 11 km (7 miles) to the south shoreline of Kilauea Volcano, the staff of the Hawaiian Volcano Observatory welcomed the public to our Open House in the Park, celebrating the twentieth anniversary of the eruption.
