Evaluation of New Yogyakarta International Airport (NYIA) in Temon District Based on Tsunami Disaster Risk using Geographic Information System (GIS)

Abstract

Yogyakarta is a province that has an appeal to be visited by the domestic and foreign visitors. Two important factors that cause people to go to Yogyakarta are many tourism places and good educational institutions. Because of the increase in the number of passengers and the bustle of activity in Adisucipto airport (previous Airport), in 2012 the central and local government of Special Propince of Yogyakarta unveiled a new airport, which it is now still in progress and targeted to be completed in 2019. The election of new airport site is very close to the subduction zone of Eurasia and Indo-Australia plates where it frequently occures earthquakes and high probability of tsunami. In this study, to predict the risk level of the tsunami, we use the Crunc model, which the multiplication of the hazard to the vulnerability and subsequently modeled by Geographic Information System (GIS). Based on the simulation of tsunami wave height of 15 meters, There are 690.73 Ha (18.78%) of Temon Distrcit area which are medium risk while 210.239 Ha (5.71) of Temon District area with high risk. In addition, low risk in NYIA area is about 14.38 Ha (2.54%) and medium risk in NYIA area is near 440.84 Ha (77.88%). The area which has high risk in the NYIA area is about 110.81 Ha (19.57%).
