The Potential of Liquefaction-Induced Lateral Spreading in Erbaa (tokat-Turkey)

Abstract

The liquefaction potential of Erbaa (Tokat) in Turkey settlement has been evaluated in this study. The study area is located partly on an alluvial plain of Kelkit river within the North Anatolian Fault Zone (NAFZ). In order to investigate the liquefaction potential of the area, geotechnical investigations including geological mapping, drilling with in-situ tests and sampling were conducted. Based on the analysis, the potential of liquefaction-induced lateral spreading displacements are investigated as a part of the microzonation study of Erbaa. The empirical methods proposed to estimate liquefaction-induced lateral spreading employ the ground inclination and the thickness of liquefiable ground layer generally through regression analyses. The northwestern part of Erbaa reveals a higher lateral spreading displacement potential than the rest of the study area considering lateral spreading analyses.
