Abstract

In Pohang, several roads has been damaged by liquefaction occurrence and attention has been paid to disaster prevention roads. This study is a case study using GIS mapping for disaster prevention road in Pohang where the biggest earthquake damage occurred in Korea in 2017. To simulate the earthquake risk of road, we predicted liquefaction potential and collapse of old non-seismic buildings against two earthquakes with return period 500 and 1,000 years. For GIS simulation, liquefaction assessment was conducted based on the survey data of the regional area. Based on the results, the liquefaction potential index as a liquefaction risk and dangerous old roadside buildings under earthquake loading were also shown on the map.
