movie shows video taken during today's field visit and overflight. The first portion of the video is taken at the rim of Pu`u `Ō `ō crater, and shows the north vent feeding the lava pond. The lava surface undulates due to rising gas bubbles, and a small overturn is triggered.

Field measurements at about 4;00 p.m. on Wednesday, June 9, 2010 at gage 13246000, North Fork Payette River near Banks, Idaho. Measured discharge was at 7,500 cfs. Beginning the weekend of June 3-4, the Payette rose quickly to above flood stage. The peak of record for this gage is 8,830 cfs, recorded May 11, 1947.

movie shows the active lava pond within Pu`u `Ō `ō crater, imaged with a thermal camera. The video is shown at x60 speed, and covers about 25 minutes. Lava is being supplied to the crater from two vents, one visible in the upper right corner of the image and one out of view in the lower left.

Development can have negative effects on streams in urban and suburban areas.

video from a thermal camera looking into the vent cavity at Halema`uma`u around 3pm today. The video is shown at x4 speed. At the beginning of the clip, the lava level is at a high stand, with slowly migrating crustal plates and little spattering. Eventually, small scale spattering begins in the northeast corner of the pond, accompanied by vigorous degassing.

A New USGS documentary video exploring the world of the mojave desert tortoise

The May 18, 1980 eruption of Mount St. Helens triggered a growth in volcano science and volcano monitoring. Five USGS volcano observatories have been established since the eruption. With new technologies and improved awareness of volcanic hazards USGS scientists are helping save lives and property across the planet.

On September 30, 2009 a M7.6 earthquake struck off the west coast of Sumatra, Indonesia, near the cities of Padang and Pariaman, affecting an area with a population of 1.2 million people. The Indonesian government estimates that the earthquake caused 1,195 deaths and significant damage to around 140,000 houses and 4,000 buildings.

The Submersible Habitat for Analyzing Reef Quality (SHARQ) is a new tool scientists use to understand and map metabolic characteristics associated with marine communities living on the sea floor. This podcast gives a closer look at how scientists use SHARQ to analyze important habitats like coral reefs.

Mark DeMulder, Director of the U.S. Geological Survey's National Geospatial Program (NGP) is featured as part of a panel discussion at the annual Association of American Geographer's conference in Washington DC, mid-April 2010.  The presentation includes:

Urban development is associated with an increase in impervious surfaces, that is, surfaces such as rooftops, sidewalks, and streets that prevent precipitation from infiltrating into the groundwater.  Impervious surfaces increase the volume and energy of stormwater that reaches streams and can lead to adverse physical and water quality impacts, including erosion

movie shows the lava surface deep within the Halema`uma`u vent cavity, captured with a thermal camera that can see through the thick fume. The lava surface is about 70 meters (230 ft) wide, and remains about 200 meters (660 ft) below the cavity rim. The surface is mostly crusted, with a slow migration from north to south.
