In this study, the failure mechanism of the shore landslide which occured at
Degirmendere coast region during 17 August 1999 Kocaeli (Izmit) - Turkey
earthquake is analyzed. Geotechnical studies of the region are at hand, which
reveal soil properties and geological formation of the region as well as the
topography of the shore basin after deformations. The failure is analyzed as a
landslide and permanent displacements are calculated by Newmark Method under
17 August 1999 Izmit record, scaled to a maximum acceleration of 0.4g. There
are discussions on the main dominating mechanism of failure / landslide,
liquefaction, fault rupture and lateral spreading. According to the studies,
the failure mechanism is a seismically induced shore landslide also triggered
by liquefaction and fault rupture, accompanied by the mechanism of lateral
spreading by turbulence. A seismically induced landslide is discussed and
modeled in this study. The finite element programs TELSTA and TELDYN
are employed for static and dynamic analyses. Slope stability analyses are
performed with the program SLOPE. The permanent displacements are
calculated with Newmark Method, with the help of a MATLAB program,
without considering the excess pore pressures.
