Abstract: Tsunamis often hit the Southern coast of Java, where Parangtritis is located in the area, this is due to the meeting of the Indo-Australian plate with the Eurasian plate in Southern Java which produced a tectonic earthquake as the main source of the tsunami. Tsunami waves from this area take 50-100 min to reach the coast. Considering the short period for the process of selfpreservation, this study is necessary to draw up a map of the vulnerability of the region to the tsunami evacuation route to design and place a Temporary Evacuation (TES) tsunami in the coastal village of Parangtritis. The material used as the object of study in this study is tsunami hazard, tsunami runoff based on run-up height, proposed evacuation routes and Tsunami Evacuation Sites (TES). the results are that Parangtritis is included in tsunami-prone areas with a percentage of the tsunami-prone area of 66.45%. At the time of the tsunami run-up as high as 16 m, the total area of the runoff was 788.07 ha. There are three proposed evacuation routes via. Parangtritis, Depok and Depok-Parangtritis roads. There are 12 proposed temporary evacuation sites scattered in Parangtritis village.
