Cross-correlation studies with seismic noise

Classical and Quantum Gravity, 2002
Ocean waves interacting in shallow water at the shore generate land waves propagating inland. To study these waves vertical, horizontal and tilt seismic noise were measured simultaneously at one location. Vibration isolators designed for gravitational wave research were used for detection.

The correlation-refraction method of seismic surveying

Geophysics, 1946
Abstract This paper presents a method of refraction shooting which has been developed to solve the problem of obtaining seismic data in the Edwards Plateau region of West Texas. The results of an experimental survey in the Todd Area, Crockett County, Texas, are shown to illustrate the method.

Correlated Seismicity of the Northern California Region

2020
In the Northern California region, the transform fault and related transcurrent faults are running between oceanic ridges, and this tectonic situation is different with that of the subduction boundary in the Japanese region. The characteristic features of the seismicity in the Northern California region are possibly investigated by the correlated ...

Grading system for seismic reflections and correlations

Geophysics, 1947
Abstract The modern reflection seismograph places progressively more emphasis on continuous profiling. The use of the continuous profile method automatically makes possible the computation of dip and the plotting of dip cross sections.

Complex‐valued correlation and seismic attributes

SEG Technical Program Expanded Abstracts 2009, 2009
The detection and characterization of discontinuities such as faults in seismic images can be performed by coherency analysis. I analyze the coherency of the instantaneous phase of the complex seismic trace by using circular statistics and defining a complex-valued correlation. The method, applied to neighbouring seismic traces, can extract at once two

Seismic Performance and Aging: A Correlation Study

IEEE Transactions on Power Apparatus and Systems, 1983
The effects of time/temperature and operational cycling aging mechanisms on seismic performance of safety-related equipment was investigated. The approach was to perform seismic tests on identical samples of electrical and electronic safety-related components which had been preconditioned.

Applications of Seismic-Wave Polar Correlation

1984
Polar correlation, now a well-established technique with a wealth of practical experience to its credit, has seen two periods in its development.
