Seismic Safety Margins Research Program: Phase II program plan (FY 83-FY 84)

Description: The Seismic Safety Margins Research Program (SSMRP) is an NRC-funded, multiyear program conducted by Lawrence Livermore National Laboratory (LLNL). Its goal is to develop a complete, fully coupled analysis procedure (including methods and computer codes) for estimating the risk of an earthquake-caused radioactive release from a commercial nuclear power plant. The analysis procedure is based upon a state-of-the-art evaluation of the current seismic analysis and design process and explicitly incl… more

Seismic hazard analysis for the NTS spent reactor fuel test site

Description: An experiment is being directed at the Nevada Test Site to test the feasibility for storage of spent fuel from nuclear reactors in geologic media. As part of this project, an analysis of the earthquake hazard was prepared. This report presents the results of this seismic hazard assessment. Two distinct components of the seismic hazard were addressed: vibratory ground motion and surface displacement. (ACR)

Some comments on the Shiva spaceframe earthquake damage

Description: On January 24, 1980, at 11:00 a.m., an earthquake, measuring 5.5 on the Richter scale, shook the Livermore Valley. There were three very pronounced shocks, the first at 5.5 followed by two, one at 5.2 and the other at 4.8, on the Richter scale. The Shiva spaceframe was shaken out of alignment. Shiva consists of two frames, a laser frame and a target frame. Components on each frame stayed within alignment with respect to each other, but the target frame moved with respect to the laser frame. She… more

Earthquakes: Risk, Detection, Warning, and Research

Description: This report discusses the National Earthquake Hazards Reduction Program (NEHRP), a program under which the federal government supports efforts to assess and monitor earthquake hazards and risk in the United States. This report also discusses earthquake hazards and risk in the United States; federal programs that support earthquake monitoring; the U.S. capability to detect earthquakes and issue notifications and warnings; and federally supported research to improve the fundamental scientific und… more

Enhanced Observations with Borehole Seismographic Networks. The Parkfield, California Experiment

Description: The data acquired in the Parkfield, California experiment are unique and they are producing results that force a new look at some conventional concepts and models for earthquake occurrence and fault-zone dynamics. No fault-zone drilling project can afford to neglect installation of such a network early enough in advance of the fault-zone penetration to have a well-defined picture of the seismicity details (probably at least 1000 microearthquakes--an easy 2-3 year goal for the M<0 detection o… more

Feasibility of Monitoring Rock Fall in Yosemite Valley using Seismic Methods

Description: Public awareness of rock-fall hazard in Yosemite Valley has heightened after events in 1996 and 1999. Reports of audible blasts prior to rock-fall events suggest that rock cracking may in some instances precede the detachment a block from the cliff face. Seismic methods may be used to detect and locate small, inaudible rock cracking events, resulting in a catalog that outlines active areas and quantifies the level of activity. In order to test the feasibility of monitoring rock-fall activity wi… more

P-wave arrival times for the 1991 racha, Georgia earthquake sequence at stations of a test, sparse network

Description: The following arrival information is a supplement to Myers and Schultz (2000). Myers and Schultz (2000) demonstrate the improvement in sparse-network location that can be achieved by using travel-time corrections determined with a Bayesian Kriging algorithm (Schultz et al., 1998). Precise, benchmark locations are provided by a local aftershock study of the 1991 Racha, Georgia earthquake sequence in the Caucasus Mountains (Fuenzalida et al., 1997). A test network is used to relocate the aftersho… more

Regional Seismic Signals from Chemical Explosions, Nuclear Explosions and Earthquakes: Results from the Arizona Source Phenomenology Experiment

Description: Routine industrial mining explosions play two important roles in seismic nuclear monitoring research: (1) they are a source of background events that need to be discriminated from potential nuclear explosions; (2) as some of the only explosions occurring in the current de facto global moratoria on nuclear testing, their signals should be exploited to improve the calibration of seismic m monitoring systems. A common issue monitoring arising in both of these roles is our limited physical understa… more

Tectonic stability and expected ground motion at Yucca Mountain

Description: A workshop was convened on August 7-8, 1984 at the direction of DOE to discuss effects of natural and artificial earthquakes and associated ground motion as related to siting of a high-level radioactive waste (HLW) repository at Yucca Mountain, Nevada. A panel of experts in seismology and tectonics was assembled to review available data and analyses and to assess conflicting opinions on geological and seismologic data. The objective of the meeting was to advise the Nevada Nuclear Waste Storage … more

Recovery characteristics of high damping elastomers used in seismic isolation bearings.

Description: The protection of nuclear and civil structures from the destructive effects of earthquakes has been the focus of intense research and development throughout the world. Seismic isolation is an effective means for reducing and even eliminating the devastating consequences of earthquakes on people, equipment and structures. Engineers have developed many devices for implementing the seismic isolation strategy and the most effective and economical ones have been identified through the test of time. … more
