Teleseismic P-residual study in the Iberian Peninsula

摘要: Abstract Teleseismic P-wave residuals, cleared of the effects various source regions and deep mantle paths, reflect composition structure lithosphere asthenosphere beneath seismological stations. We use a method with which we compute two components relative residuals for each station, namely directionally independent average azimuth-incidence angle dependent terms, also ACH 3-D inversion method. The representative averages show consistent variations over Iberian Peninsula relatively steep gradient in some areas—the Massif Betic Cordillera. These changes attain values around 1 s distance about 200 km. lateral these residual are transformed into tentative model thickness. A thick is observed Massif, Pyrenees, part Waves from events at different teleseismic distances azimuths provide patterns systematic directional dependence especially stations
