| Popis: |
The objective of this paper is to calculate the Moho depth and Vp/Vs ratio using Receiver Functions with time domain deconvolution (Ligorria & Ammon, 1999). Such values were obtained using the program PWSS (Phase Weighted Slant Stacking method; Bianchi, 2008). The teleseismic waveforms were obtained from four broadband seismographic stations belonging to the Seismological Observatory (SIS-UnB): BRA7 (BrasiliaDF), CAN3 (Cana Brava-GO), FOR1 (Fortaleza-CE) and SFA1 (Serra do Facao-GO). The figures of crustal thickness were considered satisfactory, varying from 34.6 Km to 41.1 Km and the Vp/Vs ratio varying from 1.65 to 1.86, being consistent with previous studies. |
