Abstract

Liquefaction is an earthquake ground failure mechanism that occurs in loose, saturated granular sediments and has caused extensive damage to the ground. Liquefaction potential zoning is the process of estimating the response of soil layers under earthquake excitations. Ground conditions play important roles in the prediction of hazards caused by earthquake. Thus to evaluate seismic hazards for a wide area, ground formation history along with soil properties must be known. This paper describes the ground conditions and behavior of Satte city as a result of Earthquake. In this paper, Geographical Information System (GIS) is used to obtain soil liquefaction hazard map. Spatial variations of soil properties are estimated from the available borehole locations where SPT –N values, water table depth and grain size distribution are known. These maps can be useful for assessing the approximate areas affected by hazards and for disaster prevention planning.
