Application of passive seismic to shallow geological structures in urban areas

To study the shal low geo log i cal struc ture the Re frac tion Microtremor (ReMi) method was ap plied. This tech nique uses seis mic noise anal y sis where a source of this small vi bra tions is the hu man ac tiv ity e.g.: traf fic, pro duc tion, fac tories. The sur veys were car ried out in se lected ur ban ar eas in the re gion of the Up per Silesian In dus trial Dis trict: Sosnowiec–Pogoñ , Chorzów–Chorzów Stary and Bytom–Karb. Each area is char ac ter ized by the pres ence of nearby roads with a very high traf fic. The re sults of pas sive seis mic (ReMi) were con fronted with data ob tained us ing Mul ti - chan nel Anal y sis of Sur face Waves (MASW) and re sis tiv ity im ag ing (RI). Seis mic sur veys were per formed by ap pa - ra tus PASI with 24 chan nels us ing geo phones of 4.5Hz. The re sults showed that pas sive seis mic can be sat is fac to rily used in such ur ban con di tions. The shal low geo log i cal struc ture in ter preted by seis mic meth ods have been well-cor re - lated with re sis tiv ity stud ies.
