(a) An example of raw receiver gather at station 487 showing notable backscattering of surface-waves marked by black arrows. (b-d) The same receiver gather as (a) but after different processing stages, (b) after the application of refraction static corrections, (c) after spectral equalization, deconvolution, time variant filter and median filter, and (d) after surfaceconsistent residual static corrections and top mute.

... this reason, when possible, processing steps were carried out on receiver gathers. An interesting phenomenon of this dataset is the strong presence of back-scattering of surface-waves in some parts of the profile (Figure 4). Given their clear locations, they are used in this study to complement the interpretation of imaging results. ...

... the strong surface waves back-scattering observed in the data (i.e., Figure 4), it was important to further analyze their properties. The Zerwer et al. (2005) method, as implemented for multifold data by Colombero et al. (2018), was applied to estimate the location of sharp lateral variations in the subsurface and the corresponding maximum affected wavelength. ...

A tsunami (plural: tsunamis or tsunami; from Japanese(harbor wave) also known as a seismic sea wave is a series of waves in a water, generally in an ocean or a lake.
In seismic nuclear monitoring, attenuation models are important prerequisites for reliably estimating the explosive yield in an uncalibrated region without the occurrence of standard events. The seismic moment obtained by fitting source spectra is related to the source energy. This approach is appropriate for estimating yield, as the attenuation ef...
