Preliminary Seismic Risk Maps for Puget Sound
Ground shaking during Puget Sound earthquakes is characterized by irregularly shaped areas of high intensity ground motion, not all of which are correlated with soil type. Simulation of...
Seismic Acceleration Maps for Oregon
To evaluate the seismic hazard for the Corps dams in the Portland District, operating basis earthquakes (OBE) and maximum credible earthquakes (MCE) were established for seismic zones...
Systems Model for Water Supply Following Earthquakes
The water supply for San Francisco is described with emphasis on the city's auxiliary water distribution network, which provides fire protection for the most heavily built-up...
Earthquake Risks to Utah Water and Gas Systems
Designed to guide local earthquake hazard reduction programs, this study estimates direct aggregate earthquake damage to Davis and Salt Lake County utilities. For making these loss estimates,...
Landslide Dammed Lakes at Mount St. Helens, Washington
The collapse of the north face of Mount St. Helens on May 18, 1980, and the debris avalanche that resulted blocked outflow from Spirit Lake and Coldwater and South Fork Castle Creeks....
Design and Construction of the Spirit Lake Outlet Tunnel, Mount St. Helens, Washington
In 1982, a governmental task force was formed to evaluate the hazard posed by the blockage of Spirit Lake that resulted from the eruption of Mount St. Helens in May 1980. An analysis was...
The 1983 Landslide Dam at Thistle, Utah
The Thistle, Utah, landslide began rapid movement on April 13, 1983. The landslide, a reactivation of an estimated 22 multiplied by 10**6 m**3 of old landslide debris, blocked Spanish...
Control of Thistle Lake, Utah
In April of 1983, the Thistle slide blocked the flow of the Spanish Fork River and traffic using the Denver and Rio Grande Western Railroad, U. S. Highway 89, and U. S. Highway 50 and...

Non-Freeway Programwide 3R Accident Analysis: New York
The New York Program for restoration, rehabilitation and resurfacing (3R's) has relied on broad scoped projects and case-by-case consideration of exceptions to design standards...
An Analysis of Traffic Signal Safety Improvements
Identifying high accident rate locations and determining that they have an overrepresented type or pattern of accidents is an important first step in the safety improvement process. However,...
Location and Development of Safety Projects
Projects to be considered for inclusion in the Highway Safety Improvement Program (HSIP) must be part of a prioritized listing in which each project is based on accident experience or...
U.S.-Japan Coordinated Program on Masonry Research
An overview of the U. S. -Japan Coordinated Program on Masonry Research is presented. The program consists of parallel efforts in Japan and the United States to develop design methods...
Sequential Earthquake Response of an Earth Dam
Sequential earthquake-response records of the well-instrumented Long Valley earth dam (Mammoth Lake area in California) are analyzed and engineering interpretations are made. The dam,...
Evaluation of Building Response Recorded During the Morgan Hill Earthquake
On April 24, 1984, the Morgan Hill Earthquake (Richter magnitude 6. 2) occurred within approximately 15 km of IBM Corporation's computer-equipment manufacturing facility located...
Dynamics of Fender and Rack Systems for Docking Ferries
A dynamic analysis of a ferry fender and rack system is developed based on the conservation of energy principle and Newton's laws of motion. The dynamics of the interaction...
