| Abstract: | SKS and SKKS waveforms from 16 events occurring between 2003 and 2005 in the Tonga Trench that were recorded by the BOLIVAR array are analyzed to determine the structure of the D layer beneath the Galapagos Islands.248 differential travel-time residuals of SKKS-SKS are measured and reveal a region of positive residuals of differential travel times in the northeast portion of the sampled region.Analyzing correlation statistics between the measured SKKS-SKS residuals and the observed absolute travel time dela... |
| Keywords: | SKKS-SKS D structure plume formation anisotropy differential travel-time residuals |
