3-D Shear Wave Velocity (Vs) & Crustal Interface (Sediment Basement & Moho) Models of Borneo, Makassar Strait, & Sulawesi Region

An update version of 3-D Shear Wave Velocity (Vs) & Crustal Interface (Sediment Basement & Moho) Models of Borneo, Makassar Strait and Sulawesi region obtained from group velocity tomography. Group velocity is retrieved from dispersion analysis of Rayleigh waves extracted from the ambient noise field by cross-correlating long-term recordings from 108 seismic stations over a period of 8 months (the stacked cross-correlations data are included). A 3-D shear wave velocity model then are produced via a two-stage process in which group velocity maps are computed across a range of periods and then sampled over a dense grid of points to produce pseudo-dispersion curves; these dispersion curves are then separately inverted for 1-D shear wave velocity (Vs), with the resultant models combined and interpolated to form a 3-D model.
