Sažetak
Teleseismic earthquake records from a passive array of 15 short-period and 4 broad-band seismometers are used to estimate traveltime residual patterns at the contact of the Dinarides and Pannonian basin. Estimation of relative residuals is achieved with fast and powerful stacking procedure through iterative alignment of traces. Global ak135 propagation model is used for achieving initial alignment by selecting the time window around the desired phase. Final alignment is obtained by rapid convergence of introduced time-shifts between reference trace and traces from each station. Similar residual patterns are caused by events arriving from the same region, but patterns differ if the events originate from various locations. Stations situated in the south-western part of the array show positive residuals, and stations situated in the north-eastern part of the array show negative residuals. Stations that show positive residuals are situated on thick Dinaridic crust, which explains later arrivals. Early arrivals correspond to stations situated on much thinner Pannonian crust, hence the negative residuals. Residual pattern that occurs between these two distinctive groups is characterized by alternating negative and positive residuals. This feature corresponds to ophiolitic Transitional zone characterized by strong lateral heterogeneities in the lithosphere.
