THE EARTHQUAKE OF SEPTEMBER 5, 2007 (MW=4.8) IN ALBANIA.ANALYSIS OF THE ACCELEROGRAPHIC DATA RECORDED IN DURRESI TOWN
We present in this paper the analysis of the strong motion record generated by the earthquake of September 5,2007, taken in Durresi town, western Albania. We found high value of the high-frequency filter for the recording site, κ = 0.114. Furthermore, we used the random-vibration version of the stochastic model given in Boore (2002) by computing PSRV spectra for different values of stress parameter and compared them with the measured PSRV spectra of this event. We concluded that the stress-drop release for this event is σ = 300 bars.This value is in good agreement with the thrust mechanism environment of this event and confirms the previous findings in Albania and elsewhere that associate this kind of faulting mechanism with high values of stress-drop parameter.
