This movie shows the active lava pond within PuuOo 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.

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

Introduced & discussed by USGS Ecologist Todd Esque & Ken Nussear, Wildlife Biologist 

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.

Lessons Learned for the San Francisco Bay Area

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.

In this video excerpt, we see motion from two video surveillance cameras capturing continuous daytime video data on pupfish spawning, and as seen here, other occurrences. The cameras are positioned approximately four feet above the water surface and one underwater.

Using phenology to take the pulse of our planet

By Jake F. Weltzin, Executive Director, USA National Phenology Network

This documentary presents how recent changes in the composition and quantities of African dust transported to the Caribbean and the Americas might provide clues to why Caribbean coral reef ecosystems are deteriorating and human health may be impacted.

movie shows the active lava pond deep within the Halema`uma`u vent cavity. The lava is upwelling at the northern margin of the pond (the upper margin in this view), and slowly migrating south towards the bottom of the image, where it sinks out of view. The pond is about 50 m wide. Small spattering sources appear and disappear occasionally.
