Liquefaction during the June 27, 1998 Adana-Ceyhan (Turkey) Earthquake

摘要: On June 27, 1998, a moderate earthquake measuring 5.9 on the Richter scale struck alluvial plains of Cukurova in Adana-Ceyhan region Turkey. The resulted 145 deaths, about thousand injuries and significant damage to more than ten structures. coincidence projected location release energy along fault with very vulnerable geological surface formation (the thick deposits Ceyhan River containing loose sand layers) liquefied sediments substantial thickness extensive areal distribution. Liquefaction associated ground deformations such as lateral spreading, flow failures, fissures subsidence, boils, slope failures were observed. This paper presents analyses geotechnical aspects this main emphasis observed liquefaction deformations, together characteristics. mechanisms provide valuable information seismic response soils covering most plains, an area industrial agricultural importance 2 million inhabitants. observations from also us opportunity further improve our understanding phenomena their effects that can be expected during other future events around world.
