Radar structure of earthquake-induced, coastal landslides in Anchorage, Alaska Radar structure of earthquake-induced, coastal landslides in Anchorage, Alaska
Ground-penetrating radar (GPR) was used to investigate the internal structure of two large landslides in Anchorage, Alaska that resulted from the great 1964 earthquake. The Government Hill and Turnagain Heights landslides occurred in similar stratigraphic and geographic settings, yet the style of ground deformation is different at each site. GPR data are compared with previous...

Evaluation of landslide hazards with ground-penetrating radar, Lake Michigan coast Evaluation of landslide hazards with ground-penetrating radar, Lake Michigan coast
Ground-penetrating radar (GPR) and boreholes were used to investigate a landslide-prone bluff at Sleeping Bear Dunes National Lakeshore on the northeastern coast of Lake Michigan. Based on borehole observations, sediment underlying the area is homogeneous, consisting of well-sorted, medium to coarse sand. GPR penetrated up to 20 m deep in these sediments, revealing the late Quaternary...

Popular beach disappears underwater in huge coastal landslide — Sleeping Bear Dunes, Michigan Popular beach disappears underwater in huge coastal landslide — Sleeping Bear Dunes, Michigan
In February 1995, a 1,600-foot stretch of popular beach at Sleeping Bear Dunes National Lakeshore suddenly slid into the waters of northeastern Lake Michigan. The National Park Service (NPS) immediately requested the assistance of the U.S. Geological Survey (USGS) in evaluating the hazard at the lakeshore. To protect the public, USGS and NPS scientists are conducting studies that will...

The Loma Prieta, California, earthquake of October 17, 1989: Liquefaction The Loma Prieta, California, earthquake of October 17, 1989: Liquefaction
The 1989 Loma Prieta earthquake both reconfirmed the vulnerability of areas in the San Francisco-Monterey Bay region to liquefaction and provided an opportunity to test methodologies for predicting liquefaction that have been developed since the mid-1970's. This vulnerability is documented in the chapter edited by O'Rourke and by the investigators in this chapter who describe case...

Slope basins, headless canyons, and submarine palaeoseismology of the Cascadia accretionary complex Slope basins, headless canyons, and submarine palaeoseismology of the Cascadia accretionary complex
A combination of geomorphological, seismic reflection and geotechnical data constrains this study of sediment erosion and deposition at the toe of the Cascadia accretionary prism. We conducted a series of ALVIN dives in a region south of Astoria Canyon to examine the interrelationship of fluid flow and slope failure in a series of headless submarine canyons. Elevated head gradients at...

Consolidation, triaxial shear-strength, and index-property characteristics of organic-rich sediment from the Peru continental margin: Results from Leg 112 Consolidation, triaxial shear-strength, and index-property characteristics of organic-rich sediment from the Peru continental margin: Results from Leg 112
Sites 679, 680, and 681 of the Ocean Drilling Program were drilled along an east-west transect across an organic-rich, diatomaceous, coastal upwelling facies that occurs as a shelf/slope lens along the Peru continental margin. Seven 60-cm-long, unsplit core sections from these sites were tested for consolidation, triaxial shear strength, and geotechnical index properties. The testing...
