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.

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.

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.

USGS scientists continue to monitor streamflow during the historic flooding taking place in Fargo, ND. This information provides critical information used to estimate flood dangers and helps protect lives and property.

B-roll footage taken of USGS crews measuring severe flooding during the March 2009 flooding events in Fargo, ND.

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.

Doppler radar can be used for more than predicting the weather—it can be used to record migrating birds!

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.
