This paper presents a comprehensive investigation and characterization of soil at a critical location in Yupia, Arunachal Pradesh, utilizing the combined Multichannel Analysis of Surface Waves (MASW) method. Recognizing limitations in both active and passive methods for soil characterization at shallow and greater depths, the study emphasizes the pivotal importance of incorporating optimal data acquisition and inversion parameters in any MASW survey approach. Through experimental and comparative analysis, it is concluded that the combined MASW approach offers enhanced clarity at both shallow and deeper depths, yielding more accurate shear wave velocity (Vs) profiles. The research underscores the critical role of resolution in dispersion images obtained from raw data for achieving accurate Vs profiles. By effectively integrating active and passive MASW dispersion images, this study demonstrates the efficacy of the combined MASW survey method in soil characterization, reflecting its significance for seismic risk assessment and engineering design. A detailed case study illustrates the practical application and efficacy of the combined MASW survey method in determining Vs profiles, offering valuable insights for seismic hazard mitigation strategies in the region.
