Abstract: The complexity of the regions where the landslide occurred requires a detailed survey of the site response properties of these regions. Ambient noise analysis is a common and nondestructive approach that provides more detailed information on site resonance properties characterized by directional variations. Obtaining geological information from seismic data motivates researchers to innovate and improve efficient tools for seismic wave processing. Polarization-based methods have received much attention regarding their capability to discriminate between different phases of the seismic wave based on their polarities. Using polarization filtering to extract Rayleigh wave ellipticity provides more detailed information on site resonance properties characterized by directional variations. The outputs showed better performance of the method in terms of stability and reliability of the results. Indeed, it enabled the detection of site resonance characteristics that were previously undetectable by classic Nakamura method.
