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.

Actual speed Quicktime movie showing TEB lava stream through skylight

movie shows a view into the Thanksgiving Eve Breakout (TEB) lava tube, thanks to a skylight (a hole in the roof of the tube). The lava stream, which is about two yards below the skylight, is moving swiftly downhill (the video is shown at actual speed), towards the Waikupanaha ocean entry.

Thermal video showing the new gas vent in Halema`uma`u cavity

movie shows the new gas vent which opened yesterday on the floor of the cavity in Halema`uma`u. Following this reawakening, very faint glow was observed last night for the first time since July 4

Halema`uma`u showing the lava surface deep within the cavity850

movie shows the lava surface deep within the Halema`uma`u cavity. The lava surface is relatively sluggish, with little movement and only one spattering source.

Halema`uma`u showing spattering, sloshing at the ponded lava surface

movie shows a source of minor spattering at the margin of the ponded lava surface within the Halema`uma`u cavity. Weak sloshing of the lava surface can be seen around the spattering source.

Lava surface within the cavity of Halema`uma`u

movie shows the lava surface within the cavity at Halema`uma`u. Keeping an eye on the lower left portion of the screen, one can see a large rock impacting the lava surface. This impact appears to trigger degassing and overturning that migrates across a large portion of the lava surface.

Halema`uma`u crusted lava surface and occasional spatter

movie shows activity of the lava surface deep within the Halema`uma`u cavity. The crusted lava surface is moving slowly from northeast to southwest, with occasional bursts of spatter from the margins and cracks. The first half of the movie is shown at actual speed, with the second half shown at x10 speed to convey the sense of movement and illustrate the oscillations of

'Nightshot' mode of Halema`uma`u crusted and sluggish

movie shows the lava surface within the Halema`uma`u cavity, again using 'nightshot' mode to see through the fume. The lava surface this evening was considerably more crusted and sluggish than on previous nights, and had risen a minor amount compared to much of last week. The lava migrates from the top of screen towards the bottom, with occasional bubble bursts disrupting

'Nightshot' mode movie of Halema`uma`u rolling lava surface

movie shows the roiling lava surface within the cavity in Halema`uma`u. The video was captured in 'nightshot' mode in order to see through the fume, which obscured viewing by the naked eye. Vigorous upwelling occurs in the northeast (upper right) corner of the opening, with the southwest corner consisting of passively sloshing, and partly crusted lava.
