Abstract

A magnitude 5.4 earthquake struck the city of Pohang, South Korea on November 15 2017. Many sand volcanoes were observed on paddy fields, parks and roads. This phenomenon was the first time to observe as a sign of soil liquefaction in South Korea. In this study, two different kinds of ejected Pohang sands were collected from a liquefied paddy field. Those sands were reconstituted into loose and dense conditions and then a series of cyclic simple shear tests were carried out under confining stresses of 100 and 200 kPa. A real earthquake motion was repetitively applied into the specimen. As a result, the loose sand was liquefied at the second earthquake motion and the dense sand was at third earthquake motion.
