Açıklama : Within the confines of this study, seismic performance of the existing Bakacak landslide during November 12, 1999 Duzce, Turkey, earthquake of Mw= 7.2 is assessed. For the purpose, two cross sections of the creep-ing soil slope were numerically modeled and shaken by Bolu acceleration time history record scaled down to 0.6 g, consistent with the level of excitation expected at the site during the earthquake. The inclinometers in-stalled revealed that the amount of lateral displacements at these cross sections were 28 and 2 cm, respec-tively. Based on the yield acceleration values, estimated as 0.07 and 0.14g by pseudo-static slope stability analyses, Newmark seismic displacements were found to be 26 and 3 cm, which are in close agreement with the actual measured values. Both the close agreement in the magnitudes of permanent seismic displacements and the similarities of the actual and numerically-estimated shear zones are found to be encouraging for the use of numerical seismic response analyses techniques in the assessment of permanent seismic slope dis-placements.
