Final Report On Task 12: Southern Great Basin Seismic Network Operations, James N. Brune, David Von Seggern, Ken Smith, Glenn Biasi

Publications (YM)

The Nevada Seismological Laboratory began seismic monitoring operations under the DOE-UCCSN Cooperative Agreement on 11/01/1999. This final report summarizes our activities and studies made in the four years up to 09/30/2003. Previously, NSL operated under the M&O for the Yucca Mountain Project from October 1995 through September 1999 and under the U. S. Geological Survey from October 1992 through September 1995. For purposes of this report, earthquakes occurring in the years FY1998 and FY1999 were analyzed in the first two years of the NSL’s involvement with the Cooperative Agreement, and they will be treated here, along with the data in …

Longbase Laser Strainmeter Measurements From The South Ramp Of The Yucca Mountain Facility, Frank K. Wyatt, Duncan C. Agnew, James N. Brune, Amy J. Smiecinski

Publications (YM)

Under subcontract (DOE/UCCSN DE-FC28-98NV12081, Task 7) from the Seismological Laboratory of the University of Nevada-Reno, the University of California, San Diego (UCSD), has designed, installed, and operated a laser strainmeter (LSM) in the Exploratory Studies Facility (ESF) at Yucca Mountain, Nevada. This instrument provides precise deformation monitoring of the (proposed) repository block. This document describes the history of the installation, outlines the principles of operation of the system, documents the integral recording and control system and file formats used, and provides information on how QA has been implemented, with the aim of being a self-contained description which could be used …

Seismcity In The Vicinity Of Yucca Mountain, Nevada, For The Period October 1, 2000 To September 30, 2001, David H. Von Seggern, Kenneth Smith, James N. Brune, Richard Quittmeyer, Amy J. Smiecinski

Publications (YM)

Starting on October 1, 1995, the monitoring of seismicity within the southern Great Basin near Yucca Mountain was performed with a new digital network. This network features three-component recording with 24-bit A/D conversion in the field. Continuous data are collected at 20 sps, and event triggered windows are collected at 100 sps. A seismic bulletin of events is made by automatically associating triggers among stations, classifying the local earthquake events, and locating the earthquakes and computing their magnitudes with conventional methods. This report covers the operational and seismic results of the sixth full year (FY01) of the improved, digitally based, …

Task 1: Geodetic Monitoring Of The Yucca Mountain Region Using Continuous Global Positioning System Measurements, Jonathan Price

Publications (YM)

The principal purpose of the cooperative agreement is to develop and continue providing the public and the Yucca Mountain Site Characterization Office (YMSCO) with an independently derived, unbiased body of scientific and engineering data concerning the study of Yucca Mountain as a potential high level waste repository. Under this agreement, the University and Community College System of Nevada (UCCSN) will perform scientific or engineering research, and develop and foster collaborative working relationships between the Government and academic researchers. The following describes the objectives of Task 1 “Geodetic Monitoring of the Yucca Mountain Region Using Continuous Global Positioning System Measurements” under …

TASK 26: Upgrade of Earthquake Simulation Facilities in the Large-Scale Structures Laboratory at University of Nevada Reno

The objective of this Task was to purchase, install and commission the equipment necessary to upgrade two existing shake tables in the Structures Laboratory at UNR, from uniaxial to biaxial motion.

It was recognized that a parallel effort, funded by NSF and HUD, to add a third biaxial table with identical properties to the upgraded existing tables, would be undertaken at the same time.
