ILP TASK FORCE on SEDIMENTARY BASINS 2010 International Workshop November 7-12, 2010, Tirana (Albania) 1D-VELOCITY MODELS and LATERAL CONTRASTS in ZONES DIVIDED by SHKODER-PEJA FAULT (ALBANIA) ORMENI Rr (1) and NAZAJ Sh (2) (1) Polytechnic University, Institute of Geosciences, Tirana, “Don Bosko” street Nr.60, rrapo55@yahoo.com (2) Polytechnic University, Mining and Geology Faculty, Tirana, “Elbasani” street, The Shkoder-Peja transversal deep fault of northeastern direction founded since the beginning of the Alpine cycle: during neotectonic stage, in the Pliocene-Quaternary, it was reconstructed with garben Gomsiqe-Puka-Iballa and Bajram Curri depression situated along it. This fault zone is potential transversal seismogenic belt in Albania and nearby. In the past centuries strong earthquakes have been generated at the extremities of this fault. In the future it is expected to generate strong earthquakes for the Shkoder-Peja deep fault of powerful structural reconstruction during the Pliocene-Quaternary. 1D-velocity models of zones crosses by Shkodra-Peja deep transversal fault are computed at VELEST software of system SEISAN, inverting re- depths. The interpretation of the obtained 1D velocity models allows us to infer picked P-wave and Swave arrival time recorded in period of time 2002-2009 by the Albanian, Montenegro, and Macedonia seismic networks. Smooth velocity gradients with depth and low P-wave velocities are observed beneath two half-spaces crosses by Shkodra-Peja of the Albania Orogen. The lateral velocity difference in zones crosses this fault are as large as 2-6% and disturb in depth 0-30 km. The localizations based on 1D velocity models in presence of 2D or 3D velocity in homogeneities will be systematically shifted in the direction of increasing velocities. Since the difference increases with depth, the hypocenters are not only offset from the real fault but seem to mark even a slightly inclined fault, which is not the case. Precisely this is the cause for larger systematic misallocation and the determined fault to be deviated from the real fault. We defined reference velocity models for these zones for better constrain the hypocentral determination, in particular the hypocentral depths The interpretation of the obtained 1D velocity models and lateral velocity differences across Lushnje-Elbasan-Diber deep fault zones allows us to infer interesting features on the deep structure of the northen Albania. These results represent a first step towards more detailed Seismotectonic analyses. 127
