Confirmation and calibration of computer modeling of tsunamis produced by Augustine volcano, Alaska Confirmation and calibration of computer modeling of tsunamis produced by Augustine volcano, Alaska
Numerical modeling has been used to calculate the characteristics of a tsunami generated by a landslide into Cook Inlet from Augustine Volcano. The modeling predicts travel times of ca. 50-75 minutes to the nearest populated areas, and indicates that significant wave amplification occurs near Mt. Iliamna on the western side of Cook Inlet, and near the Nanwelak and the Homer-Anchor Point...

Growth and collapse of Hawaiian volcanoes Growth and collapse of Hawaiian volcanoes
This special issue is an outgrowth of a session of the same name held at the 2003 Fall Meeting of the American Geophysical Union (AGU) in San Francisco. The session served dual purposes: to highlight recent advances in our understanding of the development and internal structure of Hawaiian volcanoes, and to recognize the important contributions of James Moore to this field of study.

Estimating landslide losses - preliminary results of a seven-State pilot project Estimating landslide losses - preliminary results of a seven-State pilot project
Introduction: In 2001, the U.S. Geological Survey Landslide Hazards Program provided funding for seven State geological surveys to report on the status of landslide investigation strategies in each of their States, and to suggest improved ways to approach the tracking of landslides, their effects, losses associated with the landslides, and hazard mitigation strategies. Each State was to...

Chemical and isotopic database of water and gas from hydrothermal systems with an emphasis for the western United States Chemical and isotopic database of water and gas from hydrothermal systems with an emphasis for the western United States
Chemical and isotope data accumulated by two USGS Projects (led by I. Barnes and R. Mariner) over a time period of about 40 years can now be found using a basic web search or through an image search (left). The data are primarily chemical and isotopic analyses of waters (thermal, mineral, or fresh) and associated gas (free and/or dissolved) collected from hot springs, mineral springs...

Overview of the Microscopic Imager Investigation during Spirit's first 450 sols in Gusev crater Overview of the Microscopic Imager Investigation during Spirit's first 450 sols in Gusev crater
The Microscopic Imager (MI) on the Mars Exploration Rover Spirit has returned images of Mars with higher resolution than any previous camera system, allowing detailed petrographic and sedimentological studies of the rocks and soils at the Gusev landing site. Designed to simulate a geologist's hand lens, the MI is mounted on Spirit's instrument arm and can resolve objects 0.1 mm in size...

Special issue: The changing shapes of active volcanoes: Recent results and advances in volcano geodesy Special issue: The changing shapes of active volcanoes: Recent results and advances in volcano geodesy
The 18 papers herein report on new geodetic data that offer valuable insights into eruptive activity and magma transport; they present new models and modeling strategies that have the potential to greatly increase understanding of magmatic, hydrothermal, and volcano-tectonic processes; and they describe innovative techniques for collecting geodetic measurements from remote, poorly...
The changing shapes of active volcanoes: History, evolution, and future challenges for volcano geodesy The changing shapes of active volcanoes: History, evolution, and future challenges for volcano geodesy
At the very heart of volcanology lies the search for the 'plumbing systems' that form the inner workings of Earth’s active volcanoes. By their very nature, however, the magmatic reservoirs and conduits that underlie these active volcanic systems are elusive; mostly they are observable only through circumstantial evidence, using indirect, and often ambiguous, surficial measurements. Of...

The Hayward fault The Hayward fault
This field guide consists of eleven stops at sites that illustrate the geological, geophysical, geographic, and engineering aspects of the Hayward fault in the East Bay. Section I (Stops 1–4) consists of stops that are part of the University of California at Berkeley (UC-Berkeley), including research facilities, retrofit of campus buildings, and geomorphic features along the fault...

An overview of the global variability in radiated energy and apparent stress An overview of the global variability in radiated energy and apparent stress
a global study of radiated seismic energies ER and apparent stresses τ a reveals systematic patterns. earthquakes with the highest apparent stress occur in regions of intense deformation and rupture strong lithosphere. in oceanic settings, these are strike-slip earthquakes (τ a up to 27 Mpa) occurring intraplate or at evolving ends of transform faults. at subduction zones and...

King of the 40th parallel - Discovery in the American West King of the 40th parallel - Discovery in the American West
This book recounts the life and achievements of Clarence King, widely recognized as one of America’s most gifted intellectuals of the nineteenth century, and a legendary figure in the American West. King’s genius, singular accomplishments, and near-death adventures unfold in a narrative centered on his personal relationship with his lifelong friend and colleague, James Gardner. The two...

A semi-empirical model for the estimation of maximum horizontal displacement due to liquefaction-induced lateral spreading A semi-empirical model for the estimation of maximum horizontal displacement due to liquefaction-induced lateral spreading
During the 1906 San Francisco Earthquake, liquefaction-induced lateral spreading and resultant ground displacements damaged bridges, buried utilities, and lifelines, conventional structures, and other developed works. This paper presents an improved engineering tool for the prediction of maximum displacement due to liquefaction-induced lateral spreading. A semi-empirical approach is...
