The attenuation of coda wave in Alborz and NW Zagros has been estimated using the single backscattering (SBS) and the single isotropic scattering (SIS) methods at 9 frequency bands with central frequencies of 1, 1.5, 2, 3, 4, 6, 8, 12 and 16 Hz. The datab... see more

The Armutlu Peninsula, is located in a geologically complex system on the North Anatolian Fault Zone and inside the high populated Mar- mara Region. Due to its location and importance, the Marmara Region has been subject to various studies in the past; no... see more

In this study, the attenuation of coda waves has been estimated in the western part of Iran plateau using single backscattering method. Coda wave attenuation was estimated at seven central frequencies (fc = 1.5, 3, 4.5, 6, 9, 12, 18 Hz) and eigh... see more

The Armutlu Peninsula, is located in a geologically complex system on the North Anatolian Fault Zone and inside the high populated Marmara Region. Due to its location and importance, the Marmara Region has been subject to various studies in the past; now,... see more

Seismic coda measurements retrieve parameters linked to the physical characteristics of rock volumes illuminated by high frequency scattered waves. Space weighting functions (SWF) and kernels are different tools that model the spatial sensitivity of coda ... see more

We comprehensively analyze attenuation factor in Kopili region and its neighboring area. Corresponding to influence of frequency on attenuation, QP and QS are estimated from direct P and S waves. The results establishes higher values of Q for S waves (QS=... see more

The attenuation properties of Delhi & surrounding region have been investigated using 62 local earthquakes recorded at nine stations. The frequency dependent quality factors Qa (using P-waves) and Qb (using S-waves) have been determined using the coda nor... see more

Volcanoes and fault zones are areas of increased heterogeneity in the Earth crust that leads to strong scattering of seismic waves. For the understanding of the volcanic structure and the role of attenuation and scattering processes it is important to inv... see more

The spectral analysis of fifty-five KEG VBB records from the October 12, 1992 Cairo earthquake source regionwas performed to obtain the seismic moment. We obtained this parameter in turn to develop empirical local magnitude(ML), seismic moment (Mo), coda ... see more
