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...

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...

Chapter B. The Loma Prieta, California, Earthquake of October 17, 1989 - Highway Systems Chapter B. The Loma Prieta, California, Earthquake of October 17, 1989 - Highway Systems
This paper summarizes the impact of the Loma Prieta earthquake on highway systems. City streets, urban freeways, county roads, state routes, and the national highway system were all affected. There was damage to bridges, roads, tunnels, and other highway structures. The most serious damage occurred in the cities of San Francisco and Oakland, 60 miles from the fault rupture. The cost to...

Velocities of the Pine Island, Thwaites, and smaller glaciers along the Marie Byrd Land coast, West Antarctica Velocities of the Pine Island, Thwaites, and smaller glaciers along the Marie Byrd Land coast, West Antarctica
Average velocities for time intervals ranging from 1 to 15 years were measured by tracking ice-surface patterns on sequential Landsat and European Remote-sensing Satellite synthetic aperture radar images. Velocities ofThwaites Glacier range from 2.2 km a−1 above the grounding line to 3.4 km a−1 at the limit of measurements onThwaites Glacier ice tongue. The glacier increases in velocity...

The Loma Prieta, California, Earthquake of October 17, 1989: Performance of the built environment The Loma Prieta, California, Earthquake of October 17, 1989: Performance of the built environment
Professional Paper 1552 focuses on the response of buildings, lifelines, highway systems, and earth structures to the earthquake. Losses to these systems totaled approximated $5.9 billion. The earthquake displaced many residents from their homes and severely disrupted transportation systems. Some significant findings were: * Approximately 16,000 housing units were uninhabitable after the

Scenic drive landslide of January-March 1998, La Honda, San Mateo County, California Scenic drive landslide of January-March 1998, La Honda, San Mateo County, California
The small rural town of La Honda, Calif., is an unincorporated region of San Mateo County situated in the Santa Cruz Mountains in the western part of the San Francisco peninsula. Much of the town is underlain by a previously recognized ancient landslide complex. The ancient slide complex covers about 1.0 to 1.25 km2, parts of which have been historically active. This report describes a...

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

Experimental investigations regarding the use of sand as an inhibitor of air convection in deep seismic boreholes Experimental investigations regarding the use of sand as an inhibitor of air convection in deep seismic boreholes
Tilt has been the nemesis of horizontal long period seismology since its inception. Modern horizontal long period seismometers with their long natural periods are incredibly sensitive to tilt. They can sense tilts smaller than 10-11 radians. To most readers, this is just a very very small number, so we will begin with an example, which should help to illustrate just how small 10-11...

The United States Geological Survey Flagstaff Field Center was founded by the late Eugene Shoemaker in 1963 as a research site for the new science of planetary geology. Flagstaffs clear air and high elevation made it a desirable location for telescope observations of the Moon and planets and nearby Meteor Crater was a superb training ground for the Apollo astronauts. There, and in the...
