“…The Temon District area has relatively flat coastal characteristics in the form of sea plain. Marine plain is a quite dangerous condition because tsunami waves can propagate through this landform [8]. The velocity of tsunami propagation is influenced by the depth of the seabed, where the deeper the sea, the higher the tsunami velocity will be, up to hundreds to thousands of kilometers per hour with small wave heights, while shallow waters have low velocity with a higher tsunami wave height.…”

The southern coastal area of Java Island is a subduction area confluence of the Eurasian Plate and the Indo-Australian Plate. The southern area of Temon District, Kulon Progo Regency includes the Central Java-East Java megathrust area. Megathrust Central Java-East Java has a maximum earthquake potential of 8.9 Mw which has the potential to cause a tsunami disaster. The built-up land area in Temon District has a potential threat from the danger of tsunami inundation. The purpose of this study is to (1) analyze the danger of tsunami inundation in Temon District and (2) determine the area of built-up land affected by tsunami inundation. The method used in this study is descriptive quantitative-qualitative. TUNAMI-N3 was used in numerical modelling to determine tsunami inundation hazards and Google Earth Engine was used in analyze built-up land in Temon District. The results of tsunami inundation hazard treatment and built-up land areas were analyze using ArcGIS 10.8 to determine built-up land affected by the potential tsunami inundation hazard. The results showed that the tsunami generated from the earthquake scenario with a magnitude of Mw 8.9 had a maximum height of 19.86 meters with an average travel time of 33 minutes to reach the coastal area of Temon District. Temon District affected by tsunami inundation hazard has a tsunami area of 2.47 km2 with details of a low tsunami danger level of 0.67 km2, medium tsunami danger of 0.95 km2 and high tsunami danger of 0.85 km2. The maximum height of the tsunami inundation bath is 6.54 meters. Temon District has a built-up land area of 14.308 km2. Built-up land affected by tsunami inundation is 0.55 km2 with details of 0.14 km2 at low danger of tsunami inundation, 0.20 km2 at medium danger of tsunami inundation and 0.21 km2 at high tsunami inundation hazard.

On January 27, 2017, the Indonesian Government started building a new international airport in Yogyakarta Province, named Yogyakarta International Airport (YIA) to replace Adisucipto International Airport. YIA is located near the beach, which means that an awareness of natural disasters, such as coastal flooding, is essential. One of the causes of sea water flooding is land subsidence phenomenon. This land subsidence phenomenon can be monitored by using Sentinel-1 Interferometric Synthetic Aperture Radar (InSAR) data. To monitor the crustal deformation, the data used in this research are from years 2016-2019. The data were processed through LiCSBAS software which is published by the COMET in the UK. In the processing scheme, interferograms with many unwrapping errors are detected and removed via loop closure. Reliable time series and velocities are extracted using several noise indices, with the help of masking. The results show the subsidence phenomenon in the YIA area (up to 25 mm).
