Lava within the Halema`uma`u vent cavity

movie shows lava within the Halema`uma`u vent cavity, at a depth of about 200 m below the vent rim. The lava surface, which is about 20 m wide, is extremely vigorous, with constant roiling and semi-continuous spattering. Spatter deposited on the walls around the lava surface creates a hot, unstable surface, which can be seen to disintegrate as large blocks break off and

Disappearance of the lava pond within Halema`uma`u

movie shows the disappearance of the lava pond deep within the Halema`uma`u vent cavity during the early morning hours of October 3. The lava surface undergoes two filling and draining cycles, and then retreats to deeper levels in the conduit, completely out of view, around 2 am.

Cycles of filling and draining within Halema`uma`u

movie shows lava pond activity within the Halema`uma`u vent cavity captured with the low-light camera situated at the Halema`uma`u Overlook. The entire night of Oct 1-2, 2009, is shown here in 26 seconds, so the speed of the video is increased considerably. You can see many cycles of filling and draining, with each cycle lasting about two hours. There is also alternating

Fluid motion of pāhoehoe flow at Royal Gardens subdivision

This video shows the remarkable fluid motion of a finger of pāhoehoe flowing into an old skylight at the top of Royal Gardens subdivision. The movement of the viscous lava resembles that of soft-serve ice cream.

Collapse of the unstable walls within Halema`uma`u vent

movie shows two separate rockfalls impacting and disrupting the active lava pond in Halema`uma`u. Rockfalls here result from collapse of the unstable walls of the vent cavity, and are a common occurrence. The first rockfall impacts the lava surface vertically, while the second features small vertical impacts followed by a slide of material that forces the lava surface to

Vigorous spattering deep within Halema`uma`u vent

movie shows vigorous spattering at the northeast margin of the lava pond that is deep within the Halema`uma`u vent cavity. The lava surface, cut by incandescent cracks, is slowly migrating towards the southeast (down in this image). The lava pond has been visible the last several nights in the Halema`uma`u Overlook webcam (see 'webcams' link above).

Spattering deep within Halema`uma`u vent

movie shows spattering on the northeast margin of a small lava pond deep within the Halema`uma`u vent cavity. The video was shot in "nightshot" mode, which provides improved views through the thick fume at night. Each spatter burst represents a gas bubble, or bubbles, breaking at the surface.

Brown plume event within the Halema`uma`u vent cavity

movie shows a brown plume event resulting from a collapse within the Halema`uma`u vent cavity. Later views into the vent cavity with a thermal camera revealed that the floor of the vent cavity—at about 200 yards below the vent rim—had fallen away, deepening the vent cavity even further.

Thermal movie showing a view inside the Halema`uma`u vent cavity

movie shows a view into the Halema`uma`u vent cavity with a thermal camera. To the naked eye, the vent is entirely obscured by thick fume, but the thermal camera can 'see' through much of this and provide views of the cavity interior. These views show four puffing holes on the floor of the cavity. North is to the right. The 3:13am explosion originated from one of the

Explosion from the vent in Halema`uma`u

An explosion at 3:13am from the vent in Halema`uma`u ejected hot particles about a hundred yards above the vent rim, and several tens of yards above the Halema`uma`u Overlook. This Quicktime movie (shown at x2 speed) shows the event captured by a low-light camera in the HVO observation tower.

Two degassing holes on the floor of Halema`uma`u

movie shows two degassing holes on the floor of the Halema`uma`u cavity. Lava is just below the rim of the two holes, creating frequent spattering which falls around their rims. Within the larger of the two (on the right), lava can be seen vigorously sloshing. For scale, these openings are about 10 yards wide. The first half of the movie is shown in normal mode, with the

Halema`uma`u changing of the typical white to dusty brown plume

movie shows a recent instance of the Halema`uma`u changing from its typical white to a dusty brown. The brown plume events are normally associated with collapses of the cavity walls.
