Description 272-283
This study assesses geotechnical properties and probable natural hazards of the Lara-Kundu area, regarding the impacts of urbanization on the geological environment and vice-versa. Soils of the area are of dune and lagoon origin. Plasticity index of the clays varies from 39 to 57 % and the water content is between 26-45%. Plasticity index of peats varies from 65 to 117 % and the water content is between 226-405%. Su values are 29-91 kPa. Compressibility index of clay samples are Cc=0.217-0.385 and OCR values range from 0.86 to 1.06. Compressibility index of peat samples range from 0.387 to 0.637. Some buildings constructed in the study area suffer from foundation-settlement problems. Tilting or differential settlement in the study area occurs due to high compressibility. Seismic activity can be grouped into two; crustal earthquakes (0-40 km) and subduction zone earthquakes (40-140 km). Maximum observed magnitude of the subduction earthquakes is Mw=6.0, and that of the crustal earthquakes is Mw=6.6. It can be concluded that the study area is prone to hazardous earthquakes. Another issue which should be considered is that saturated soft clay, peat and loose sand can result in ground amplification. For some loose sand levels liquefaction potential should be considered. Antalya has Mediterranean climate and after a dry summer a heavy rainfall comes resulting in flood with economic and life loss.
