Global Seismic Hazard Assessment Program (GSHAP) in continental Asia Global Seismic Hazard Assessment Program (GSHAP) in continental Asia
The regional hazard mapping for the whole Eastern Asia was coordinated by the SSB Regional Centre in Beijing, originating from the expansion of the test area initially established in the border region of China-India-Nepal-Myanmar- Bangla Dash, in coordination with the other Regional Centres (JIPE, Moscow, and AGSO, Canberra) and with the direct assistance of the USGS. All Eastern Asian...

Debris-flow deposition: Effects of pore-fluid pressure and friction concentrated at flow margins Debris-flow deposition: Effects of pore-fluid pressure and friction concentrated at flow margins
Measurements of pore-fluid pressure and total bed-normal stress at the base of several ∼10 m3 experimental debris flows provide new insight into the process of debris-flow deposition. Pore-fluid pressures nearly sufficient to cause liquefaction were developed and maintained during flow mobilization and acceleration, persisted in debris-flow interiors during flow deceleration and...

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...

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...

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 Loma Prieta, California, earthquake of October 17, 1989: Landslides The Loma Prieta, California, earthquake of October 17, 1989: Landslides
Central California, in the vicinity of San Francisco and Monterey Bays, has a history of fatal and damaging landslides, triggered by heavy rainfall, coastal and stream erosion, construction activity, and earthquakes. The great 1906 San Francisco earthquake (MS=8.2-8.3) generated more than 10,000 landslides throughout an area of 32,000 km2; these landslides killed at least 11 people and...

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...

A method for producing digital probabilistic seismic landslide hazard maps: An example from the Los Angeles, California, area A method for producing digital probabilistic seismic landslide hazard maps: An example from the Los Angeles, California, area
The 1994 Northridge, California, earthquake is the first earthquake for which we have all of the data sets needed to conduct a rigorous regional analysis of seismic slope instability. These data sets include (1) a comprehensive inventory of triggered landslides, (2) about 200 strong-motion records of the mainshock, (3) 1:24,000-scale geologic mapping of the region, (4) extensive data on
