Results of the Galileo solid state imaging (SSI) experiment Results of the Galileo solid state imaging (SSI) experiment
We present a brief synopsis of the nature of SSI data that was taken during the nominal Galileo mission. Significant results are briefly described. These include evidence for geologic activity on Europa that supports the hypothesis of liquid water under a thin ice shell; a demonstration of the ubiquitous presence of a thick crust and high temperature silicate volcanism on Io; a...

Landslide Hazards Landslide Hazards
Landslide hazards occur in many places around What Can You Do If You Live Near Steep Hills? the world and include fast-moving debris flows, slow-moving landslides, and a variety of flows and slides initiating from volcanoes. Each year, these hazards cost billions of dollars and cause numerous fatalities and injuries. Awareness and education about these hazards is a first step toward...

Peligros de deslizamientos [Landslide Hazards] Peligros de deslizamientos [Landslide Hazards]
Deslizamientos, flujos de escombrera y desastres geológicos similares provenientes de volcanes ocurren alrededor del mundo. Cada año estos desastres causan billones de dólares en pérdidas y un sinnúmero de fatalidades y heridos. El primer paso para reducir los efectos dañinos causados por estos desastres es el conocimiento y educación acerca de ellos. El Servicio Geológico de los Estados...

Compositional analyses of small lunar pyroclastic deposits using Clementine multispectral data Compositional analyses of small lunar pyroclastic deposits using Clementine multispectral data
Clementine ultraviolet-visible (UVVIS) data are used to examine the compositions of 18 pyroclastic deposits (15 small, three large) at 13 sites on the Moon. Compositional variations among pyroclastic deposits largely result from differing amounts of new basaltic (or juvenile) material and reworked local material entrained in their ejecta upon eruption. Characterization of pyroclastic...

Methane Hydrate Dissociation Rates at 0.1 MPa and Temperatures above 272 K Methane Hydrate Dissociation Rates at 0.1 MPa and Temperatures above 272 K
We performed rapid depressurization experiments on methane hydrate under isothermal conditions above 272 K to determine the amount and rate of methane evolution. Sample temperatures rapidly drop below 273 K and stabilize near 272.5 K during dissociation. This thermal anomaly and the persistence of methane hydrate are consistent with the reported recovery of partially dissociated methane...

How useful is landslide hazard information? Lessons learned in the San Francisco Bay region How useful is landslide hazard information? Lessons learned in the San Francisco Bay region
Landslides, worldwide and in the United States, are arguably the most costly natural hazard. Substantial landslide information is available, but much of it remains underutilized, as a disconnect exists among geologists, decision makers, and the public. The lack of a national landslide insurance policy exacerbates this situation and promotes litigation as the principal recourse for...

Data for Quaternary faults in western Montana Data for Quaternary faults in western Montana
The "World Map of Major Active Faults" Task Group is compiling published fault data, developing a digital database of the fault data, and preparing a series of maps for the United States and other countries in the western Hemisphere. The data is intended to portray the locations, ages, and activity rates of major earthquake-related features such as faults, folds, and liquefaction...
