Disasters can cause many loss of life and property every year. Although sudden disasters such as earthquakes and tsunamis cannot be detected in advance, knowing where and when disasters may occur or quickly determining the impact area of a disaster is the main factor in preventing these losses. For this reason, many different measurement methods have been developed by various professional disciplines in order to examine disasters. One of these methods is the Interferometric Synthetic Aperture Radar (InSAR) method, which is a remote sensing method. In this study, the 2015 Chile Illapel earthquake with the Differential SAR Interferometry (DInSAR) method based on the InSAR method, the vertical deformations and change analysis in the Konya Karapınar district, and the California Carr fire with the Permanent Scatterer SAR Interferometry (PS-InSAR) method were investigated. As a result of the investigations, the deformation in the LOS direction in the 2015 Chile Illapel earthquake region was found to be ∼151 cm and the vertical deformations in the Konya Karapınar district were found in the range of 6.4 to -63.7 cm. Additionally, the initial and full spread area of the California Carr fire were determined.
