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.

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.

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.

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.

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.

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.

movie shows a draining event in the Halema`uma`u lava lake. Filling and draining cycles have been observed before here, but this video is one of the clearest examples thus far. The video is shown at actual speed, with draining taking about 40 seconds. Note the draining is highly unsteady, and proceeds in a step-wise fashion.

video shows another rare view of the active lava surface deep within the cavity in Halema`uma`u crater. The lava is approximately 100 m below the floor of Halema`uma`u. The lava surface is disrupted by waves, splashes, bubbling and upwelling, with overall lava movement from the upper right to the lower left.

movie shows the behavior of the active lava at the base of the cavity in Halema`uma`u crater. Lava emerged in the upper right and flowed towards the lower left. The surface was disrupted by a chaos of waves, splashes, bubble bursts and spattering. The video is shown at actual speed.

movie shows recent activity observed within the Halema`uma`u vent with a thermal camera. The video speed is approximately x30. Cycles of filling and draining of the lava lake have been observed throughout much of the past week, following a collapse in the vent on March 25. Filling-draining frequencies have ranged from about 10 to 20 cycles per hour.

movie shows the robust brown plume associated with a hybrid seismic event at 11:03 am. Brown plumes such as this have appeared occasionally throughout the past year of eruptive activity at the summit, and are often associated with rockfalls.

movie shows a thermal video providing views into the Halema`uma`u vent. At a depth of about 130 yards below the vent rim, there is a series of small puffing gas vents, and these occasionally throw small amounts of spatter into the air. The configuration and geometry of these small puffing vents have been observed to change on a daily basis.

movie shows the new ocean entry within the National Park, near the location of the buried Poupou-Kauka West archeological site. The entry consists of a series of narrow lava cascades falling onto the rocks at the base of the sea cliff.

This video shows thermal imagery of the vent inside Halema`uma`u crater. The lava surface, about 130 yards below the vent rim, is clearly visible and can be seen undergoing cycles of filling and drainback. Filling phases entail a rapidly rising lava level with intense (and loud) spattering, followed by a gradual phase of lava draining back down the conduit.

movie (x3 speed) shows the latest explosive eruption from the vent in Halema`uma`u, which occurred at 7:28am. A robust, ash-rich mushroom cloud is ejected, and followed by pulses of hot, glowing gas and particles. The explosion deposited a field of fist-size ejecta around the crater rim.

movie of the October 12 explosive eruption captured by a camera located on the rim of Halema`uma`u just above the vent. The camera was completely engulfed in the ash cloud, turning day to night, then bombarded by falling ejecta.

movie (x3 speed) shows an ash event from the vent in Halema`uma`u, occurring at 3:54 pm. The normally white degassing plume is rapidly overwhelmed with a vigorous ash-rich pulse that rises rapidly from the vent. Red flashes above the vent indicate hot, incandescent material being ejected.

Movie shows a roiling, bubbling lava surface approximately 100 yards beneath the rim of the vent within Halema`uma`u. This is the first clear view of lava within the vent, which opened on March 19, 2008. The video was taken from a helicopter hovering over the Halema`uma`u overlook area.

Movie, in 'nightshot' mode and zoomed in on the Halema`uma`u vent, shows the explosive eruption which occurred at 8:13 pm. This eruption carpeted the area around the Halema`uma`u crater rim with ejecta as large as 8 inches long.

Video shows an ash-emission event at 6:53pm on August 31 from the vent in Halema`uma`u crater. The event begins with a robust pulse of ash, followed shortly by flashes of bright incandescence that rise about 50 yards above the vent.

Movie shows a small explosive eruption, at 7:37 am, from the vent in Halema`uma`u crater. The normal white degassing plume is rapidly overwhelmed by a more robust, ash-rich plume that rises rapidly from the vent. This is the fifth explosive eruption since the new vent at Halema`uma`u appeared in mid-March.
