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.

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.

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.

This short video gives an overview of the USGS Menlo Park Science Center in California. It briefly introduces you to the San Francisco Bay Area, shows the campus and facilities, and includes interviews with scientists describing their work.

This video gives a brief overview of the U.S. Program for the Indian Ocean Tsunami Warning System.
It includes footage of the deployment of the first Indian Ocean Tsunami Detection (DART) buoy in December 2006, of a simulation exercise in Padang, Indonesia, a training course in seismology that took place in 2007, as well as interviews with scientists.

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.

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.
