Time-series of dome & glacier growth at Mount St. Helens, WA

The video shows time-lapse changes in the lava dome and Crater Glacier from 2004-2012. The images were created from 1:12,000 scale vertical aerial photographs combined with ground control points from campaign GPS and targets. Photogrammetry software was used to collect a 3-D point cloud and combined to make a digital elevation model (DEM).

Video showing a 6 m (20 ft) high lava cascade near the eastern base of Pu‘u ‘Ō‘ō. This is the same lava stream shown in the previous two videos. The lava stream continues on several hundred more meters (yards) before transitioning into rubbly pāhoehoe and ‘a‘ā and stalling well short of yesterday’s flow front, which is now inactive.

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.

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.

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.

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.

(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 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.

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.

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.

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.

Halema`uma`u Lava Lake

Movie of the lava lake in Kīlauea's summit vent in Halema‘uma‘u crater minutes after a slice of the vent wall had plunged into the lava. The lava lake is roiling violently as the recently added wall debris is digested by the lava. Slabs of rock can be seen breaking loose from the base of the overhanging vent wall and falling into the lava.
