Sažetak
We have used teleseismic events recorded at temporary seismic stations from the ALPASS-DIPS experiment to estimate the crustal structure of Istra peninsula and SW Pannonian basin. The data were analysed by P receiver function method based on the converted P-to-S phase generated at significant velocity discontinuities in the crust and upper mantle. Forward modelling of receiver functions was used to construct crustal shear-velocity models under the stations. The receiver function results can be compared with results from wide-angle seismic experiment in this area. The receiver functions analysis at stations deployed in Istra have showed that crustal velocity models fit to Dinaridic type with three major discontinuities within the crust. Whereas, models with single-layered crust could fit well observed receiver functions in the Pannonian basin. The crustal thickness for stations in the SW Pannonian basin is 25.5 – 28 km, and for Istrian stations it is in the range from 37 to 43 km.
