Cyclic stress ratio of landslide deposits in Vinodol Valley, Croatia

Earthquakes are among the most significant landslide triggering factors. Earthquake induced vibrations produce small cyclic shear strains, and the resulting cyclic stresses gradually increase pore pressure. The Vinodol Valley is characterized by numerous relatively small and shallow debris slides, initiated in eluvial deposits, or along the contact between the eluvial deposits and flysch bedrock. The area of the Vinodol Valley is seismically active, which makes it susceptible to earthquake triggered landslides. In this study, three samples were collected from the landslide body of a debris slide and tested under three different cyclic stress ratios for the first time within the presented studied area. The preliminary results enabled insights into an understanding of possible earthquake impact on cyclic behaviour of soils from the eluvial deposits in the Vinodol Valley.
