The Theory of Coda Wave Interferometry
Pure and Applied Geophysics, 2006Coda waves are sensitive to changes in the subsurface because the strong scattering that generates these waves causes them to repeatedly sample a limited region of space. Coda wave interferometry is a technique that exploits this sensitivity to estimate slight changes in the medium from a comparison of the coda waves before and after the perturbation ...

The analysis and interpretation of coda waves have received increasing attention since the early seventies. In the past few years interest in this subject has spread worldwide, and the study of high-frequency seismic coda waves has become a very important seismological topic.

Synthesis of Coda Waves in Layered Medium
pure and applied geophysics, 1988Malin’s (1980) first-order single scattering theory has been extended to study the scattering of surface waves as well as body waves by distributed point scatterers in a layered medium. The scattered waveform itself is generated and examined instead of its energy envelope.

Comparison of Sesimic Body Wave and Coda Wave Measures of
Pure and Applied Geophysics, 1998Measurements of seismic attenuation (Q −1) can vary considerably when made from different parts of seismograms or using different techniques, particularly at high frequencies. These discrepancies may be methodological, or may reflect earth processes.

Coda waves viz. the tail portion of an earthquake record have been observed and analysed byCarder, Macelwane and others. They showed that the periods of such waves increase with the increase of epicentral distances.Carder observed that these waves have very little transverse component so that these may be considered as of the type of Rayleigh waves ...

Phenomenological Study of Coda Waves
2011The excitation of S-coda waves is one of the most compelling pieces of evidence supporting the existence of random heterogeneity in the lithosphere. Aki and Chouet (1975) first summarized the characteristics of high-frequency S-coda waves of local earthquakes as follows: (1) the spectral contents of the later portions of S-coda are the same at ...

The attenuation of coda waves in the RIF area.
2020<p>This work is presenting the attenuation of coda waves in the Rif region. Using 15 broadband stations, we investigate the attenuation of coda waves utilizing the single backscattering model of aki and chouet. We collect 70 local earthquakes during 2014 for five laps time window 20, 30, 40, 50 and 60s.
