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.

'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.
'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.

Halema`uma`u lava lake draining event
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.

Another rare look into Halema`uma`u crater
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.

As the Lava Churns
On June 4, 2009, conditions provided a rare view of active lava churning within Kilauea Volcano's summit vent located in Halema'uma'u Crater. This video (actual speed) shows the surface of the circulating lava, which is about 100 meters (300 feet) below the crater floor, or 180 meters (590 feet) below the camera.

Halema`uma`u crater
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.

Tsunami Preparedness along the West Coast, USA
Tsunami Preparedness explains how and why tsunamis occur, how to know that a tsunami is approaching, and what you should do. These issues are addressed by scientists, emergency managers, and first responders.

Tsunami Preparedness in Northern California, USA
Tsunamis are a constant threat to the coasts of our world. Although tsunamis are infrequent along the California coast, it is possible and necessary to prepare for potential tsunami hazards to minimize loss of life and property. Community awareness programs are important, as they strive to create an informed society by providing education and training.

Effects of Sea-Level Rise on Coastal Wetlands in the Mississippi Delta
This video describes research being conducted by Dr. Karen McKee, USGS Research Ecologist, and her university partner, Dr. Julia Cherry. Their goal is to better understand the effects of sea-level rise and other global change factors on coastal wetlands in the Mississippi River Delta. This region contains over 40% of the U.S.

Halema`uma`u vent with thermal camera
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.

Robust brown plume
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.
