Abstract

The settlements around Lake Van are generally located on young, unconsolidated, saturated, Quaternary aged, current lake and stream sediments. The region is under active tectonism, and many destructive earthquakes have occurred in the area both recently and in historical times. The site effect plays a very crucial role in the prediction of earthquake damage to existing structures and in the planning and design of new structures. The main purpose of this study is to determine the mechanical and physical properties of soils in and around the settlement area of Van and to determine their behaviour under a possible earthquake. Considering these situations, both borehole-based geological data and data obtained from geophysical methods were collected in the Van settlement area.
