This video 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, until the lake finally disintegrates. By the end of the sequence, the lava lake is gone and floor has dropped about 80 meters (260 ft). Around 3:15pm, you can see a portion of the rim, at the very right end of the image, collapse into the crater.
This video 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 only hot rubble and inclined blocks of the pre-existing crater floor. The temperature scale is degrees Celsius.
This video 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 video shows activity at some of the individual vents, which are each distinct in their behavior.
