This study investigates the method and application of single-channel, three-component microtremor signal co-directional Rayleigh surface-wave extraction. The research focuses on filtering linear polarization waves using polarizability wave phase-difference filtering, which were analyzed based both simulated data real signals. Additionally, examines use time-frequency analysis to analyze signals...

Recently, the use of microtremor techniques for subsoil investigation has increased significantly. The HVSR (Horizontal to Vertical Spectral Ratio) technique allows, in many cases, obtain a seismo-stratigraphic reconstruction and identify areas with similar seismic behavior. However, stratigraphic interpretation peaks still remains subjective choice linked priori information. A non-hierarchical...

Earth fissures are widely distributed worldwide, and the Fenwei Basin in China is one of regions with most significant number scale world. The Yuncheng an important constituent basin China, where earth densely developed cause severe damage. In particular, impact on seismic response site still unknown urgent problem that needs to be solved. Based microtremor tests, three types typical fissure si...
