Collapse of the Pu'u 'O 'o Crater Floor on March 5, 2011
Collapse of the Pu'u 'O 'o Crater Floor on March 5, 2011Video showing the collapse of the Pu'u 'O 'o crater floor on March 5. The video starts at 4 am and ends at 11 pm. The floor of the crater dropped about 115 meters (377 ft) in just a few hours.

Propagating Fissure
Video clip shot in front of the propagating fissure, showing low spattering that started moments earlier. Thick white steam from the crack in the foreground indicates that lava is about to reach the surface, and is seen doing so seconds later.

Fissure Eruption Between Pu'u 'O 'o and Napau Crater
Fissure Eruption Between Pu'u 'O 'o and Napau CraterVideo clip shot from the air looking SW at the fissure eruption between Pu'u 'O 'o and Napau Crater. The fissure segment in the tephra in the foreground opened seconds earlier, and only about 10 minutes after the eruption as a whole started. The cracks through the tephra are in the process of opening, though this can't be picked out at this distance.

Wall and rim collapses of Halema‘uma‘u
There was a series of vent wall and rim collapses on March 3, much like those than occurred in January and February. This video, compiled from the Webcam on the rim of Halema‘uma‘u above the vent, is one of the larger collapses, and shows the northwest rim of the vent falling into the lava lake.

Halema'uma'u North Rim Collapse
This video, compiled from the Webcam on the rim of Halema'uma'u, shows the north rim of the vent collapsing.

Rockfall in Halema'uma'u
The level of the lava lake sometimes changes abruptly. These cycles of rise and fall, which amount to a vertical change of around 15 m (about 50 ft), are occasionally triggered by rockfalls. Here, a small collapse from the vent wall triggers degassing and a drop in the lava level.

Thunder Sounds from the Vent in Halema'uma'u
Booming sounds from the vent in Halema'uma'u have been audible around the summit area of Kilauea for the past several days. Some of these sounds are caused by rocks striking the surface of the lava lake, but most are actually the sound of the vent walls cracking due to heating and expansion of rock.

Spattering in Halema'uma'u
As spattering intensifies, the walls of the vent heat even more, causing the cracking of the rocks through thermal expansion to speed up, creating the cacophony of popping noises apparent in this video.

Halema'uma'u West Rim Collapse
This clip, captured by a video camera on the rim of Halema'uma'u to the southwest of the vent, shows a small slice of the western rim of the vent collapsing into the lava lake.
