|Abstract:||The intermediate-depth earthquakes in Vrancea (Romania) are particularly notable in the group of the European earthquakes. The scope of this work is to show preliminary results of the seismic effects of 27, October, 2004 earthquake from the Vrancea seismogenic zone. Particular attention is done on the records registered in Bucharest and Sofia. The study is limited to the question about the level of the ground motions in terms of recorded spectral amplitudes during 2004 Vrancea strong earthquakes. For this purpose we discuss: (1) the strong ground motion records in due to Vrancea strong earthquake, 2004; (2) the regional seismicity and a review of the available recurrence and attenuation relationships; (3) results from the response of one storey building due to scaled record in Sofia. The results of this study confirm the significant influence of the Vrancea intermediate-depth seismogenic zone on very large territory of Bulgaria and the need to provide realistic seismic input, from Vrancea sources, for the purposes of seismic microzonation.|
