Environmental impacts on the southern Florida coastal waters: A history of change in Florida Bay Environmental impacts on the southern Florida coastal waters: A history of change in Florida Bay
Analyses of four cores located in the northern transitional, eastern, and central portions of Florida Bay reveal historical patterns of change in salinity and seagrass distribution. Salinity and the distribution of seagrass beds are two critical issues for the restoration of Florida Bay. The distribution of benthic fauna in Bob Allen 6A and Russell Bank 19B cores illustrates changes in

The Pu‘u ‘Ō‘ō-Kūpaianaha erruption of Kīlauea, November 1991–February 1994: Field data and flow maps The Pu‘u ‘Ō‘ō-Kūpaianaha erruption of Kīlauea, November 1991–February 1994: Field data and flow maps
The Pu'u 'Ō'ō-Kūpaianaha eruption on the east rift zone of Kīlauea, which began in January 1983, is the longest-lived rift zone eruption of the last two centuries. By 1994, a broad field of lava, nearly 1 km3 in volume and 12 km wide at the coast, had buried 87 km2 of the volcano's south flank. The initial six months of fissure eruptions (episodes 1-3) were followed by three years of...

Landslides triggered by the winter 1996-97 storms in the Puget Lowland, Washington Landslides triggered by the winter 1996-97 storms in the Puget Lowland, Washington
Snowmelt and rainfall events triggered many landslides and debris flows in the Seattle, Washington, area during late December 1996 and January and March 1997. Landslides caused the deaths of at least four people, millions of dollars in damage to public and private property, lost revenues, traffic diversions, and other direct and indirect losses. Although shallow slides and debris flows...

Compilation of 29 sonic and density logs from 23 oil test wells in western Washington State Compilation of 29 sonic and density logs from 23 oil test wells in western Washington State
Three-dimensional velocity models for Puget Sound provide a means for better understanding the lateral variations in strong ground motions recorded during local earthquakes in Puget Lowland. We have compiled 29 sonic and density logs from 23 oil test wells to help us determine the geometry and physical properties of the Cenozoic basins in western Washington. The maximum depths sampled by...

Landslide Hazards in Glacial Lake Clays - Tully Valley, New York Landslide Hazards in Glacial Lake Clays - Tully Valley, New York
At approximately midday on April 27, 1993, a large landslide occurred along the foot of Bare Mountain in LaFayette, Onondaga County, New York, about 12 miles south of Syracuse (figs. 1, 2). The slide moved rapidly east toward the middle of the Tully Valley and impacted approximately 50 acres of land, destroyed three homes, and resulted in the evacuation of four other homes. Debris from...

Pebble orientation on large, experimental debris-flow deposits Pebble orientation on large, experimental debris-flow deposits
Replicable, pronounced orientation of discoid pebbles (≥8 mm) embedded on surfaces of large (∼10 m3) experimental debris-flow deposits reveals that strongly aligned, imbricate fabric can develop rapidly over short distances in mass flows. Pebble long axes aligned subparallel to deposit margins as well as subparallel to margins of surge waves arrested within the deposits. Pebble alignment...

The coseismic slip distributions of the 1940 and 1979 Imperial Valley, California, earthquakes and their implications The coseismic slip distributions of the 1940 and 1979 Imperial Valley, California, earthquakes and their implications
Geodetic arrays observed by the U.S. Coast and Geodetic Survey span the Imperial fault in southern California. For the 1940 M 7.1 Imperial Valley earthquake, a 1934–1941 triangulation network has sufficient resolution to allow inversion for the coseismic slip distribution on fault segments 5 to 25 km long extending from the surface to a depth of 9 km. The estimated right-lateral slip is...
