(Received 20 August 2001, accepted 1 November 2001)} Abstract: By using two different processing codes, a splitting analysis of SKS waves has been performed at the Hungarian Station PSZ – GEOFON Network. The obtained direction of the fastest splitted wave has the mean value of 141.2° ± 8.7° (95% confidence level) when the ah_splitest2 code is used. The mean value of the delay time is 0.62 ± 0.12 seconds. By using a second code, the direction of the fastest splitted wave is 133.3° ± 8.6°. The corresponding mean value of the delay time is 0.73 ± 0.13 seconds. The results are discussed in relation to other stress indicators in the area and to the regional tectonic features.
