Assessment of liquefaction potential of fethiye based on spt and shear wave velocity

Turkey, located at an area of active seismic zone, has vast records of many earthquakes. The liquefaction phenomena have become crucial issue in Turkey since Erzincan Earthquake took place in 1992. Soil liquefaction was observed widely during Marmara and Duzce Earthquakes in 1999 as well. In this study, the liquefaction potential of vicinity of Fethiye village in Turkey was investigated via results of blow counts (N) of Standard Penetration Test (SPT) and velocity measurements of seismic refraction tests at 40 different locations in the investigated area under an earthquake magnitude (M-w) of 7.0. Liquefaction severity maps were prepared according to liquefaction severity index that is function of the input parameters such as SPT-N values, ground water level, fines content and shear wave velocity. The results of study reveal that the investigated area has either no potential liquefiable or low susceptibility liquefiable zones under M-w= 7.0.
