Analysis of the Tsunami Evacuation Route in Kunjir Village and Way Muli Village, South Lampung Regency

Abstract

This researchwas conductedto analyze the effectiveness of existing evacuation routes inKunjirVillage and WayMuliVillage by calculating the level of safety of the population when evacuating inthe event ofa tsunami disaster. The data used are direct field observations, topographic maps derived from aerial photo mapping results, existing conditions of evacuation routes, gathering conditions, evacuation direction signs, and data on tsunami wave heights that may occur in the study area. We analyze the tsunami disaster evacuation route using Network Analyst inArcGIS. Furthermore, the evacuation routeis determinedwhich has a road width of more than 2 m so that not all roads in both villagesare usedas evacuation routes. In determining the evacuation point modeling tsunami inundationis usedwith a wave height of 4 m. Later the route and direction of the nearest evacuation route will be known to the safe evacuation point. Based on the results of the study, the number of evacuation routes in WayMuliVillage amounted to 5 with 4sitepoints while inKunjirVillage there were 7 with 4sitepoints that could be used as evacuation sites. The farthest distance from the evacuation route to the evacuation site in WayMuliVillage is 441.5 m with a travel time of 4 minutes and forKunjirVillage is 704.3 m with a travel time of 6.38 minutes.
