Efficiency in the Bag
Heavy snowfalls made the existing water treatment plant at the Lassen Volcanic National Park in northern California inaccessible during winter months. As activity in the park during colder...

Natural Disaster Reduction
These proceedings contains the summaries of the presentations at the 1996 ASCE International Conference and Exposition on Natural Disaster Reduction held in Washington, D.C., December...

Terrestrial Analogs: Implications for Lunar Lava Tubes
Earlier work has demonstrated that lava tubes did form on the Moon. Comparison of terrestrial lava tubes to their lunar counterparts suggest that they are very similar despite the order...

Science Education Beyond the Classroom
The Yucca Mountain Site Characterization Project (YMP) sponsors a variety of classroom-oriented projects and activities for teachers who request them. Also available, though, are extra-curricular...

An Inverse Procedure for Estimating the Unsaturated Hydraulic Conductivities of Volcanic Tuffs
A procedure is developed for estimating the hydraulic conductivity function of unsaturated volcanic tuff, using measurements of the sorptivity and capillary pressure functions. The method...

Geophycal Investigations of Buried Volcanic Centers Near Yucca Mountain, Southwest Nevada
Several aeromagnetic dipolar anomalies occur over flat, alluvial areas near Yucca Mountain that resemble anomalies typically associated with subaerial basaltic volcanic centers. Detailed...

Volcanic Episodes Near Yucca Mountain As Determined by Paleomagnetic Studies at Lathrop Wells, Crater Flat, and Sleeping Butte, Nevada
It has been suggested that mafic volcanism in the vicinity of Yucca Mountain, Nev., is both recent (20 ka) and a product of complex 'polycyclic' eruptions. This...

⁴⁰Ar/?⁹Ar Laser Fusion and K-Ar Ages From Lathrop Wells, Nevada, and Cima, California: The Age of the Latest Volcanic Activity in the Yucca Mountain Area
K-Ar and ⁴⁰Ar/³⁹Ar ages from the Lathrop Wells volcanic center, Nevada, and from the Cima volcanic field,...

Design Considerations for the Yucca Mountain Project Site Characterization
The Site Characterization Facilities (SCF) to be located in volcanic tuff at Yucca Mountain is a challenge to manage, design, and construct. This challenge is a result of a number of factors....

Radioactive Waste: Finding a Safe Place
The Nuclear Waste Policy Act of 1981 and its amendments mandate that the U.S. Department of Energy find a repository for the nation's high-level radioactive wastes, characterize...

Hydrologic Change Caused by the Eruption of Mount St. Helens
On 18 May 1980, the eruption of Mount St. Helens created a massive landslide which covered 32 square miles and stripped all vegetation from 150 square miles. A study of changes in hydrologic...

Basaltic Volcanic Episodes of the Yucca Mountain Region
The purpose of this paper is to summarize briefly the distribution and geologic characteristics of basaltic volcanism in the Yucca Mountain region during the last 10-12 Ma. This interval...

Volcano-Tectonic Interpretations: An Example from the Northern Basin & Range
Study of volcano-tectonic relationships in the Northern Basin and Range suggests a temporal relationship between basin propagation and the inception of volvanism. The age relationships...

The Area of Most Recent Volcanism Near Yucca Mountain, Nevada: Implications for Volcanic Risk Assessment
The proposed area of most recent volcanism (AMRV) includes all known post-6 Ma volcanic complexes in the Yucca Mountain area and encompasses the four volcanic centers in Crater Flat, the...

The USGS Centennial: From Mining to Mapping the Moon
The United States Geological Survey was established 100 years ago by the U.S. Congress primarily to determine the extent of the rapidly industrializing nation's mineral resources. The...
