“…Radar interferometry or Interferometry with Synthetic Aperture Radar (InSAR) is a recent remote sensing technique that allows the study of large time series of surface movements (Akcin et al, 2010;Herrera et al, 2009;Hongdong et al, 2011;Jung et al, 2007;Zhenguo et al, 2013). The movement of reflective surfaces (i.e., the so-called permanent scatterers) is followed during successive cycles of the satellite.…”

Abstract. The surface movement in an area of about 22 km 2 above the underground coal mine of Houthalen was analyzed based on Interferometry with Synthetic Aperture Radar (In-SAR) measurements. After its closure in 1992, a residual subsidence was observed over a period of several years, followed by an uplift of the surface above and around the past longwall panels, whereby the rate of movement was, in absolute terms, of the same order for the two types of movements. The processes behind these movements are different. The process of subsidence is caused by the caving of the roof above the mined-out area and is mainly a mechanical stress-deformation process, including time-dependent aspects. However, the process of uplift is most probably caused by the swelling of the clay minerals in the argillaceous rocks in the coal strata after the flooding of the underground workings. Hence, the areas in which there is the greatest risk of damage to the surface infrastructure are not the same for the hazards linked to subsidence and uplift. For example, the zone in which the maximum uplift occurs clearly is at a different location from that of the zone with the maximum residual subsidence. There is no clear sign that the amount of mining underneath affects the residual subsidence, and there is no indication that the process of uplift is linked directly to the mining characteristics. It is more likely that uplift as the result of flooding is initiated at, or close to, the vertical shafts.

“…Radar interferometry technique provides a means to monitor earthquakes, volcanic movements, glacial movements and rebounds, landslides, surface deformations, etc. InSAR techniques have been used to determine manmade subsidences and surface swelling all over the worlds such as in Groninggen, Holland (Hanssen & Usai 1997); Pomona, California, USA (Ferretti et al 2000); Appin, Australia (Ge et al 2003); and Zonguldak, Turkey (Akcin et al 2010 Can et al (2011Can et al ( , 2012Can et al ( , 2013aCan et al ( , 2013b deal with the precise leveling and Global Positioning System (GPS) monitoring results for the basin to determine the mining-induced horizontal and vertical displacements and indicate the similar subsidence findings in the same study area. In Zonguldak-Kozlu Hard Coal Region, coal seams dip mostly at high angle, and their thicknesses are not uniform; therefore, mining subsidence problems are most likely to occur causing very serious problems with regard to urbanization.…”

Since Turkey is located on a region that is prone to the risks of natural disasters like earthquake, flooding, and avalanche; a majority of the residential areas are facing these risks at various levels. Before determination of these risks, taking action in order to decrease the vulnerability levels of the residential areas will help keep the damage at the minimum level in case of a disaster. Urban planning decisions which are made in accordance with vulnerability studies aiming to determine natural disaster risks will not only help prevent loss of life but also help decrease negative social and economic effects of disasters. The Zonguldak city has been chosen as a case study area since Zonguldak metropolitan area has endured almost all kinds of threats that a city can face. In this study disaster-producing factors in the area are primarily considered which can be named as topography, destruction of forest lands, geological and karstic structure, mining activities, and misuse of the land, and later risk assessment is conducted with geographic information system (GIS). It has been assessed that more than half of the buildings within the study area were constructed in areas not suitable for housing. It is concluded that there is a need for urgent urban development plan for the city.

“…Most applications related to deformation monitoring use GIS technology to study the influence of underground exploitation over the surface on highlighting the movement phenomenon (Malinowska & Hejmanowski 2010;Dragomir & Herbei 2012;Ghosh & Chakravarty 2012). The obtained surface deformation map is integrated with digitized mine production maps and with QuickBird orthographic images into the GIS to analyse subsidence effects (Akcin et al 2010). Underground structural deformation monitoring that adopts GIS technology has not been examined well.…”
