Trabzon province located on the shore of the Black Sea in the NE Turkey approximately 150 km distance from the North Anatolian Fault (NAF) which is the most dangerous fault system in Turkey. In addition, the 1939 Erzincan earthquake with Ms = 7.9 occurred, which caused many loss of life and property nearest to the study area on the NAF system, and after this earthquake, many more destructive earthquakes occurred on the NAF system. Determining the soil characteristics of the KTU campus in Trabzon is important in terms of reducing earthquake damages. Therefore, ambient noise recordings were carried out at 75 single-points and 2 reference points and in the five faculty buildings located in this area. The analysis of ambient noise record provided the identification of the local site-effect of KTU campus with horizontal to vertical spectral ratio (HVSR) and standard spectral ratio (SSR) methods and site-structure resonance effect of faculty buildings with floor spectral ratio (FSR) method. Contour maps of the amplification and fundamental frequency generated from HVSR and SSR have been found to be compatible. The natural frequencies of the faculty buildings are in the range of 2.5–6.7 Hz and the potential danger of site-structure resonance effect in the study area has been found as a low value. Also, vulnerability index (Kg) values were determined in the range of 0.3–8.4.
