Analyst I: Comprehensive Analysis of the UTexas1 Surface Wave Dataset
This paper details the methodologies, uncertainties, and results from analysis of the UTexas1 dataset. The vertical and horizontal seismic records from multiple field acquisitions of active-source and ambient-wavefield surface wave data were processed to obtain dispersion estimates using the frequency domain beamformer (FDBF), high resolution f-k (HRFK), modified spatial autocorrelation (MSPAC), and refraction microtremor (ReMi) methods. Rayleigh wave, Love wave, and H/V data were inverted simultaneously in the software Geopsy. The dispersion processing and inversion results indicate higher-mode behavior at frequencies less than about 5 Hz that significantly influence the interpretation of the shear wave velocity (Vs) profile. The uncertainty of the final Vs profile was estimated by calculating the counted 5% and 95% Vs range from the best 1000 profiles out of a pool of over two million searched models.
