摘要
Teleseismic waveforms recorded by the broadband seismic stations of Cuba have been analysed using the receiver function method. The thickness of the crust at seven sites on the island was found to be in agreement with previous studies. The results suggest a clear layering at some sites with a Moho depth ranging between 18 and 31 km. In eastern Cuba, the seismic stations located in the south experience thinner crust in comparison with stations located in the north, which is consistent with a southward gradual thinning revealed by other studies. The thickest crust is found at Cascorro (CCC) in the interior part of the island. The velocity models computed from the receiver-function inversion show an upper-mantle P-wave velocity between 7.6 and 8.0 km/sec. Low velocity zones are visible at some sites.
