The flow began erupting in Pu'u 'O 'o crater this morning. The primary vent for the flow was producing small pulsating spattering that had built a small rampart on its south side. The final portion of the video is shown at x10 speed with a wide view, and shows how the spattering vent is supplying the flow.

The USGS is a science organization that provides impartial information on the health of our ecosystems and environment, the natural hazards that threaten us, the natural resources we rely on, the impacts of climate and land-use change, and the core science systems that help us provide timely, relevant, and useable information.

The video relates how a team of scientists conducted rapid response sampling of coastal environments before any oil had reached land, following up in October 2010 with post-landfall sampling for comparison.

A caldera is a large, usually circular volcanic depression formed when magma is withdrawn or erupted from a shallow underground magma reservoir. It is often difficult to visualize how calderas form. This simple experiment using flour, a balloon, tubing, and a bicycle pump, provides a helpful visualization for caldera formation.

movie captures a short period of successive littoral explosions at the Puhi-o-Kalaikini ocean entry, where lava exiting the tube enters the water. The explosions were throwing ejecta up to about 20 meters. The video was taken with a high zoom factor from the top of the sea cliff, well away from the entry point and not on the lava delta.

On September, 24, 2010 The USGS briefed Congress, the media and the public on a new USGS study documenting nutrient concentrations in the Nation's water resources, key sources of nutrients, potential effects on humans and aquatic life, and changes in concentrations since the early 1990's.

The lava lake deep within the vent cavity at Halema`uma`u crater remains active, with ongoing degassing and circulation of lava. This Quicktime movie shows the view in the vent today with a thermal camera, and the video is set at x4 speed to better show the slowly moving lava surface.

During the course of our research on walruses hauled out near Point Lay in
early September, USGS obtained aerial video footage of the
walrus aggregation. This footage was taken from an altitude of 4,000' with
a Cineflex camera by Daniel Zatz, of Zatzworks, on contract to USGS for
