Abstract
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).

Summary
Airports are critical component of the aviation network. They play an important role, within the macro transport environment, and in enhancing the quality of life and the regional economies, which are directly involved in the production of wealth [1]. Evans [2] stated that airports offer all of the requisite facilities for moving passengers and freight from surface to air transportation systems and for airlines to be able to take off and land their aircraft. Airports are much more than just places for flights, corporate transit events or tax free shopping; they are one of the biggest investments for cities and regions. In the heart of the regions in which they are located, and in certain sectors of activity (e.g. tourism), airport infrastructure is of the upmost importance. Due to new market demands and trends arising in related sectors, such as the aviation industry, their positioning has been changed in recent years
