Scope of the research

The research mainly focuses on the earthquake in the convergent plate and other secondary motions, which are probably generated in the research area. Based on the physical characteristics of the research area, the study only focused on ground motion, coseismic deformation displacement, and a topographic divergence due to the rupture and the active fault.

The study used secondary data with different scales, such as land use and geology maps; the figure below (Figure. 1.3) summarizes the chapters and some of the published scientific papers.

    1. Introduction


Remote sensing-based mapping is increasingly essential. It is widely used for detecting, monitoring, and analyzing various natural disasters, including floods, earthquakes, wildfires, volcanic activity, and landslides (Joyce et al. 2009). With the 1991 launch of the European Space Agency's ERS-1 satellite, new developments emerged, enabling satellite repeat pass interferometry to provide ongoing global coverage. Following the success of ERS-1, government space agencies, and private companies launched several additional InSAR-capable satellites. Figure 2.1 lists all satellite missions that have produced publicly accessible remote sensing data in the past, present, and future. Since 1991, scientists have been able to study the Earth and its deformation in new ways thanks to the coverage provided by satellites that cover a variety of resolutions, wavelengths, and polarizations. The European satellite system ALMAZ, remote sensing Japanese earth resources satellites, and RADARS AT-1 watch, like SEASAT, operate at a single frequency and polarization. ALMAZ and RADARSAT-1 have the advantage of being able to work at various incident angles. RADARSAT-1 also offers the frequently used Scan-SAR mode, which covers a range of up to 500 kilometers. Among the most advanced SAR systems is the Shuttle Imaging Radar-C/X band SAR (SIR-C/XSAR), flown by a NASA/German Space Agency/ Italian Space Agency mission in April and October 1994. The primary emphasis of this research is RADAR. Examples of applications include radar polarimetry (McNairn et al., 2009), high-resolution imaging (Schwerdt et al., 2005), rapid repeat satellite interferometry (Rufino et al., 1998); (Krieger et al., 2007), and high-resolution imaging. The research suggests the reader consult the literature reviewing recent advancements for a more thorough overview since these only briefly touch on the capabilities of contemporary SAR satellite constellations (Bürgmann et al., 2000).

. The basic idea behind radar is that microwaves are generated from an antenna and reflect off a distant surface, allowing the signal strength and round trip time to be recorded by a receiving antenna (SZEKIELDA, 1988). Radar systems typically send and receive signals with wavelengths ranging from 1 cm to 1 m, corresponding to frequencies ranging from 300 MHz to 30 GHz (Campbell, 2002); (Moore et al., 2006) (Figure2.2).
