This animation shows how gases behave in magma and how an airplane-mounted UV spectrometer can measure gases in a volcanic plume.

The video shows time-lapse changes in the lava dome and Crater Glacier from 2004-2012. The images were created from 1:12,000 scale vertical aerial photographs combined with ground control points from campaign GPS and targets. Photogrammetry software was used to collect a 3-D point cloud and combined to make a digital elevation model (DEM).

Moving magma can deform the surface of the Earth. This animation shows how a tiltmeter and GPS are used to detect the subtle signs that tell scientists something about what is going on beneath the surface.

Earthquakes serve as an early warning sign for volcanic eruptions, as well as a marker for the location of moving magma. This animation shows magma movement beneath a volcano, simulated seismograms, volcanic tremor and seismicity associated with an impending eruption.

A live, online chat about East Coast earthquakes and the Virginia 5.8M earthquake that occurred on August 23, 2011, with Dr. Michael Blanpied, Associate Coordinator for the USGS Earthquake Hazards Program.

U.S. Geological Survey crews are measuring flooding across Louisiana, including the Morganza and Bonnet Carre Spillways. Jennifer LaVista reports on USGS flood efforts along the Atchafalaya and Mississippi Rivers.

This footage was gathered during peak water levels from the Zionsville Rd./High School Ave.

Video of flooding that took place located in French Lick, Indiana. This is a new USGS streamgage, near the Spring Resort & Casino.

This a video of flooding that took place in Edwardsport, Indiana. The video was taken on SR 358 East of Duke Power Plant. A USGS streamgage is scheduled to be installed at this site by mid summer.

Video showing the collapse of the Pu'u 'O 'o crater floor on March 5. The video starts at 4 am and ends at 11 pm. The floor of the crater dropped about 115 meters (377 ft) in just a few hours.

Video showing low fountaining from the dominant vent, near the southwest end of the fissure system adjacent to Napau Crater, active during the day on March 7.

Video showing spattering from the most persistent vent of the day just west of the base of Pu'u 'O 'o near the northeastern end of the fissure system.

This video shows lava pouring from the fissure into a seemingly bottomless crack. Napau Crater in the background. Helicopter for scale.

Video clip shot in front of the propagating fissure, showing low spattering that started moments earlier. Thick white steam from the crack in the foreground indicates that lava is about to reach the surface, and is seen doing so seconds later.

Video clip shot from the air looking SW at the fissure eruption between Pu'u 'O 'o and Napau Crater. The fissure segment in the tephra in the foreground opened seconds earlier, and only about 10 minutes after the eruption as a whole started. The cracks through the tephra are in the process of opening, though this can't be picked out at this distance.

Spattering near the front of the propagating fissure.

There was a series of vent wall and rim collapses on March 3, much like those than occurred in January and February. This video, compiled from the Webcam on the rim of Halema‘uma‘u above the vent, is one of the larger collapses, and shows the northwest rim of the vent falling into the lava lake.

This video, compiled from the Webcam on the rim of Halema'uma'u, shows the north rim of the vent collapsing.

This clip, captured by a video camera on the rim of Halema'uma'u to the southwest of the vent, shows a small slice of the western rim of the vent collapsing into the lava lake.
