Abstract

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.

不同InSAR方法对灾害的调查

灾害每年都会造成许多人的生命和财产损失。虽然地震和海啸等突发灾害无法提前发现，但了解灾害可能发生的地点和时间或迅速确定灾害的影响范围是防止这些损失的主要因素。出于这个原因，不同的专业学科开发了许多不同的测量方法来检查灾害。其中一种方法是干涉合成孔径雷达(InSAR)方法，这是一种遥感方法。本文以2015年智利Illapel地震为研究对象，采用基于InSAR方法的差分SAR干涉(DInSAR)方法，对Konya Karapınar地区的垂直形变和变化分析进行了研究，并采用永久散射体SAR干涉(PS-InSAR)方法对加州Carr火灾进行了研究。调查结果显示，2015年智利Illapel震区LOS方向形变为~ 151 cm, Konya Karapınar震区垂直形变为6.4 ~ -63.7 cm。此外，还确定了加州卡尔火灾的初始和全部蔓延面积。
