Cooper, W. Yellowknife seismological array: a Canadian contibution to the verification of compliance with a nuclear test ban treaty. The Array; Introduction. The seismological array located near Yellowknife in the Northwest Territories was established inin cooperative agreement between the Department of Mines and Technical Surveys (now Natural Resources Canada) and the United Kingdom Atomic Energy Authority (UKAEA), to investigate the feasibility of teleseismic detection and identification of nuclear explosions using multiple seismometers in distributed arrays.

Mini Arrays  The first seismological arrays built in the late s and the early s were very small circular arrays with apertures of just a few kilometers (e.g., Blue Mountain array, Uinto Basin array, Tonto Forest array, and Cumberland Plateau array [Romney, ]) built within the Vela Uniform Program (United States).

The National Earthquake DataBase (NEDB) comprises a number of separate databases that together act as the national repository for all raw seismograph data, measurements, and derived parameters arising from the Canadian National Seismograph Network (CNSN), the Yellowknife Seismological Array (YKA), previous regional telemetered networks in.
 Most array methods assume a plane wave arriving at the array. This is a good approximation for wave fronts from teleseismic events but is a restriction for the study of near-receiver structures.
The propagation direc-tion of elastic waves traveling in a spherical Earth and arriving at a seismological array can be described by two. For 30 years, the array station at Yellowknife, Northwest Territories, has demonstrated some of the best capabilities in the world for detecting seismological events and, through Canadian research programmes, has contributed significantly to the development of seismological verification techniques.

The fine scale structure of the core mantle boundary (CMB) region beneath southern Alaska is studied using core reflected P-waves (PcP) recorded at the Canadian Yellowknife c studies of the lowermost mantle have detected a multitude of structures at this contact zone between iron alloy liquid of the core and the silicates of the mantle.
Seismological arrays and networks can be used to increase the signal-to-noise ratio of seismic arrivals. By stacking seismic traces that are recorded at an array, the coherent part of the seismic wave field can be enhanced while suppressing incoherent noise.

A seismic array is a system of linked seismometers arranged in a regular geometric pattern (cross, circle, rectangular etc.) to increase sensitivity to earthquake and explosion detection. A seismic array differs from a local network of seismic stations mainly by the techniques used for data analysis.
The data from a seismic array is obtained using special digital signal processing techniques.

Abstract. The arrival at the Yellowknife Array (YKA) of closely-spaced P-waves having slightly different values ofdT/dΔ, azimuth, and amplitude has been simulated using synthetic 1 Hz ve-processing determinations of apparent slowness and azimuth show a remarkable pattern of fluctuations with time for varying separations of the interfering pulses.
Slowness (dT/d∆) and azimuth measurements for P and pP phases have been derived for 57 earthquakes at distances between 82° and ° recorded at the Yellowknife array to determine whether such data are capable of elucidating the structure of the lowest km of the mantle.
To show that systematic errors in the azimuths of arrival and slight differences in dT/d∆ values from those. Data, Results, and Discussion. We found that this doublet also was well recorded on the short-period Yellowknife seismograph array (YK) in northern Canada, which is located in an optimal position for the study of mantle phases PP as well as both refracted (PKIKP) and postcritically reflected (PKiKP) corethese phases are emitted near the maximum in the lobe of the doublet's.

Eight— Array Seismology—Past, Present and Future Developments E. Husebye and B. Ruud Introduction. Array seismology was born on Septem On that day a nuclear explosion, code-named Rainier, was detonated under the Nevada desert principally to explore the ability of an underground test, unhampered by weather and concerns over radioactive fallout, to fulfill all the needs.
Furthermore, the following topics are included: installing seismic stations, networks, and arrays - working with portable instruments - calibrating instruments - dealing with response information - and teaching about seismic instruments.
This book is primarily intended for seismologists and technicians working with seismological instruments. Short Wavelength Topography on the Inner Core Boundary Aimin Cao, Yder Masson, and Barbara Romanowicz Introduction.
