Flying at about the elevation of the plume top, this video shows a number of aspects of the ongoing activity at Halema`uma`u Crater. The mostly whitish plume rises to an elevation of about 5,500 feet and blows first to the southwest but apparently spreads to the west over the Ka`u Desert. Mauna Loa rises above the clouds in the background.

USGS scientists deliver a variety of science in the effort to restore wetlands to over 25,000 acres in San Francisco Bay. "Wetland Revival" shows how science is contributing to the transformation of once industrial salt producing ponds into more natural habitat. The program was completed in 2008. USGS General Information Product 61.

This video describes how scientists study past changes in sea-level and coastal environments by analyzing mangrove peat. Mangrove islands located off the coast of Belize are underlain by deep deposits of peat (organic soil), which retain a record of past sea level, vegetation, and climate.

Restoring San Francisco Bay Salt Ponds to Wetlands Habitat

A video production introduced and discussed by Steven E. Schwarzbach, Director, USGS Western Ecological Research Center

Today marks the 10th anniversary of the eruption within Halema‘uma‘u at the summit of Kīlauea Volcano. When the vent first opened on March 19, 2008, it formed a small pit about 115 feet (35 m) wide. Over the past decade, that pit (informally called the "Overlook crater") has grown into a gaping hole about 919 feet by 656 feet (280 x 200 m) in size.

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.
