Seismic interferometry by cross‐correlation or deconvolution?
SEG Technical Program Expanded Abstracts 2008, 2008We discuss Rodney Calvert's work on the Virtual Source method in the context of seismic interferometry. Moreover, we present a systematic analysis of seismic interferometry by cross-correlation versus multi-dimensional deconvolution and we discuss applications of both approaches.

Correlations in aftershock and seismicity patterns
Tectonophysics, 2006Correlations in space and time play a fundamental role in earthquake processes. One direct manifestation of the effects of correlations is the occurrence of aftershocks due to the stress transfer in the vicinity of a main shock. Less obvious and more speculative changes in correlations may occur in the background seismicity before large earthquakes ...

Correlation of Seismic Responses of Structures
Journal of Structural Engineering, 1997A practical analytical study is reported that leads to an improved definition of the correlation coefficient for seismic responses of structures. In contrast to definitions currently available, including the widely used expression developed for white-noise excitations by Der Kiureghian, the solution for the correlation coefficient reported in the ...

Long-Range Correlations in the Diffuse Seismic Coda
Science, 2003The late seismic coda may contain coherent information about the elastic response of Earth. We computed the correlations of the seismic codas of 101 distant earthquakes recorded at stations that were tens of kilometers apart. By stacking cross-correlation functions of codas, we found a low-frequency coherent part in the diffuse field.

Correlates of Household Seismic Hazard Adjustment Adoption
Risk Analysis, 2000This study examined the relationships of self‐reported adoption of 12 seismic hazard adjustments (pre‐impact actions to reduce danger to persons and property) with respondents' demographic characteristics, perceived risk, perceived hazard knowledge, perceived protection responsibility, and perceived attributes of the hazard adjustments. Consistent with

Seismic Delay Times: Correlation with Other Data
Science, 1967Travel-time residuals of seismic P -waves were expanded in spherical harmonics to determine their global variations. The expansion cofficients were correlated with similar coefficients of geopotential, variations in heat flow, and the surface topography of Earth. Although none of the correlation coefficients is very

Wavelet correlation filter for wide‐angle seismic data
Geophysical Prospecting, 2002ABSTRACTA new filtering technique for single‐fold wide‐angle reflection/refraction seismic data is presented. The technique is based on the wavelet decomposition of a set of adjacent traces followed by coherence analysis. The filtering procedure consists of three steps.

Correlated Seismicity of Japanese Regions
2020Seismic activity of the Japanese islands region is a part of the global seismicity dynamics, and then it should be governed by its boundary conditions embedded in the global seismicity dynamics. Thus, the downscaling of the global dynamics may be applied for the seismicity of the Japanese region.
