A050 Estimation of Quality Factor from seismic refraction data Summary 1 Several techniques for estimating the quality factor Q from refraction data have been implemented and tested on experimental data. The results show a reasonable agreement among the different estimates although the obtained values are quite small. Frequency domain techniques allow for the recognition of inherent dependence of Q from frequency in agreement with recent laboratory results and lead to estimates closer to values inferred by in situ and laboratory tests for the same geological formation in a site nearby. Introduction The estimation of dissipative properties of near surface sediments
