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...

The Loma Prieta, California, Earthquake of October 17, 1989: Forecasts The Loma Prieta, California, Earthquake of October 17, 1989: Forecasts

The magnitude (Mw) 6.9 Loma Prieta earthquake struck the San Francisco Bay region of central California at 5:04 p.m. P.d.t. on October 17, 1989, killing 62 people and generating billions of dollars in property damage. Scientists were not surprised by the occurrence of a destructive earthquake in this region and had, in fact, been attempting to forecast the location of the next large...

Chapter C. The Loma Prieta, California, Earthquake of October 17, 1989 - Building Structures Chapter C. The Loma Prieta, California, Earthquake of October 17, 1989 - Building Structures

Several approaches are used to assess the performance of the built environment following an earthquake -- preliminary damage surveys conducted by professionals, detailed studies of individual structures, and statistical analyses of groups of structures. Reports of damage that are issued by many organizations immediately following an earthquake play a key role in directing subsequent...
