Seismic Vulnerability Assessment of Seattle Water Department's Water System Facilities
The Seattle Water Department (SWD) service area and watersheds lie in seismic zone 3, in which there is potential for major earthquakes (Richter magnitude 7.5 or greater). The SWD system...
Performance of Pipelines During Soil Liquefaction
This paper presents the behavior of buried pipelines during soil liquefaction through reconnaissance work after the 1989 Loma Prieta Earthquake and response analysis based on a beam theory....
Inventory and Seismic Loss Estimation of Portland Water/Sewer Systems GIS Application to Buried Pipelines
Portland, Oregon has been identified by USGS as one of the earthquake-prone areas, in which earthquake hazard mitigation is important. This project develops an efficient and realistic...
Earthquake Loss Estimation of the Portland, Oregon Water and Sewage Systems?Evaluation of Concentrated Facilities
This paper summarizes a report that provides an inventory of concentrated water and sewage facilities in two selected drainage basins in the City of Portland. Concentrated facilities include...
Seismic Hazards for Memphis Water Delivery Systems
Estimation of seismic hazards is the first essential task in performing the seismic risk assessment of a municipal water delivery system. This paper presents the evaluation of seismic...
Economic Impact of Earthquake Effects on the City of Everett's Lifelines
The economic effects of lifelines failures, caused by three hypothesized earthquake scenarios, in the city of Everett, Washington are estimated. The project team consists of lifeline seismic...
Spectral Shapes and Amplifications for the Loma Prieta Earthquake of October 17, 1989
The 1971 San Fernando earthquake provided engineers and seismologists with the largest number of strong motion accelerograms ever recorded for an earthquake at that time. Those records...
Modeling Path Effects in the Los Angeles Region
Path effects for seismic wave propagation within three-dimensional (3-D) basin structures are analyzed using a reciprocal source experiment. In this experiment, a numerical simulation...
Liquefaction Hazard Evaluation: Methodology and Application
Deterministic liquefaction potential evaluations are commonly done in engineering practice and several probabilistic models exist. In this paper an extended method is described that combines...
Investigating Fault Rupture Hazards: An Example from the Wasatch Fault Zone, Utah
The Kern River project consists of a 36-inch diameter high-pressure natural gas pipeline, to be constructed from southwestern Wyoming to southern California. The alignment crosses several...
Liquefaction Hazard Analysis for Design of the Kern River Pipeline at the Muddy River Crossing, Southern Nevada
The 91.4-cm (36-in.) diameter Kern River natural gas transmission pipeline will cross the Muddy River in Moapa Valley, about 5 km west of Glendale, Nevada, in an area of relatively low...
Seismic Hazards Associated with a Major San Diego Lifeline Corridor
Evidence for multiple Holocene earthquakes on the Rose Canyon fault zone in San Diego sheds new light on the seismic hazards of San Diego, and in particular, a major lifeline corridor....
GIS-Based Interactive and Graphic Computer System to Evaluate Seismic Risks on Water Delivery Networks
As interactive and graphic computer system to evaluate seismic risks of an arbitrary water delivery network is developed, based on G/S (geographic information system) software, ARC/INFO....
Lifeline Seismic Risk Analysis Impacts of a Catastrophic Earthquake on U.S. National Lifeline Systems
Electric power, water, gas, and oil pipelines, highways, railroads and several other lifelines of critical importance at the U.S. national level have been inventoried and analyzed, to...
Earthquake Loss Estimation Modeling of the Seattle Water System Using a Deterministic Approach
This paper summarizes the project and resulting report entitled Earthquake Loss Estimation Modeling of the Seattle Water System (Ballantyne, 1990) conducted under funding from the United...
A Methodology for Assessing the Risk of Hazardous Materials Release Following Earthquakes?A Demonstration Study for the Los Angeles Area
A methodology for estimating the risk of post-earthquake hazardous materials releases was developed for the National Science Foundation and the National Center for Earthquake Engineering...
Seismic Vulnerability Assessment of Bridges on Earthquake Priority Routes in Western Kentucky
This paper discusses the current conditions of 203 bridges on the priority routes in Western Kentucky and their vulnerabilities to earthquakes. A span-loss type of bridge collapse due...
Seismic Vulnerability Analysis and Upgrade of Seattle Metro Wastewater Facilities
The Municipality of Metropolitan Seattle, Metro, provides wholesale wastewater transport and treatment for 30 cities and sewer districts. A Seismic Vulnerability Assessment Worksheet for...
Seismic Design Criteria for Transportation Structures
Seismic criteria for the design of transportation stuctures have evolved slowly since their inception in the early 1940s. Although seismic design criteria are far more sophisticated than...
Understanding the Earthquake Environment, Corporate Strategies
