Long-lived mud "eruption" inundates housing and infrastructure

By Thomas J. Casadevall, Geologist

(January 26, 2008, 10:50:12 to 19:12:16) Perched lava ponds often formed atop the rootless shields built by the "Thanksgiving Eve Breakout" (TEB) lava flow. This movie shows the failure of the flank of a rootless shield on January 26, 2008, and the release of the lava contained within the perched lava pond at its summit.

Just after midnight on July 21, 2007, a new fissure eruption broke out on the eastern flank of the Pu'u 'O'o cone (http://hvo.wr.usgs.gov/pressreleases/pr07_21_07.html).

The rapid onset of unrest at Mount St. Helens on September 23, 2004 initiated an uninterrupted lava-dome-building eruption that continued until 2008. The initial phase produced rapid growth of a lava dome as magma pushed upward.

Michael Shulter (USGS) Director, California Water Science Center discusses the USGS's science and collaborative efforts regarding the 2007 California wildfires.

USGS scientists talk about the importance of spectral data, the instrumentation used, and what USGS brings to the table regarding fire science.

Robert Fisher, USGS Research Biologist talks about the overall impact of fires on the biology of the area.

Adam Backlin, USGS Ecologist, talks about the potential dangers to the aquatic life in the streams around the Santa Ana Mountains as a result of the 2007 California wildfires.

Jim Bowers, USGS, California Hydrologic Monitoring Program Chief, talks about an historic streamflow site that was buried by debris flows as a result of the 2003 fires.

Jim Bowers, USGS, California Hydrologic Monitoring Program Chief talks about the potential for debris flows in central Orange County, Modjeska Canyon, as a result of the 2007 fires.

On September 21, 1966, Secretary of the Interior Stewart Udall issued a press statement stating his belief that "the time is now right and urgent to apply space technology towards the solution of many pressing natural resources problems being compounded by population and industrial growth."

The USGS Antarctic Program from the 1957 International
Geophysical Year to the 2007 International Polar Year

(December 1, 2007, 02:01:38 to 16:01:36) On November 21, 2007—the eve of the U.S. Thanksgiving holiday—Episode 58 changed dramatically. Lava, erupting from Fissure D into a perched lava channel, found an easier path to the surface and broke out from directly over Fissure D on what was, by then, the southern flank of the channel.

Just after midnight on July 21, 2007, a new fissure eruption broke out on the eastern flank of the Pu'u 'O'o cone (http://hvo.wr.usgs.gov/pressreleases/pr07_21_07.html).

(November 15, 2007, 09:00:15 to 13:00:15) Periods of overflow and levee construction at the Episode 58 lava channel were interspersed with periods when the lava level was below the channel rim. The lava surface within the lava channel commonly experienced repeated cycles of rise and fall, as shown here.

Using geoscience to help understand whether health risks lurk in particles produced by disasters

Video Highlights:

* A catastrophic 1982 rainstorm triggered 18,000 landslides in the Bay Area, claiming 25 lives and causing \$66 million in property damage

* The combination of steep slopes, weak rocks, and intense winter storms make Bay Area uplands an ideal setting for landslides

Past, Present, And Future

The USGS put together time-lapse video of the breach of the Marmot Dam, on the Sandy River in Oregon. Hydrology experts from the USGS Oregon Water Science Center and the USGS Cascades Volcano Observatory are studying this removal, the largest planned removal in the Pacific Northwest thus far.
