içerisinde yer alan Bolvadin yerleşim alanında gözlenmektedir. Bu alanda, bir kısmı imar planı içerisinde kalan bölge ile şehrin güneybatı kısmından başlayarak kuzeydoğu istikametine doğru yer alan bölgelerde, son 4 yıldan itibaren daha önceden olmayan bazı deformasyonlar oluşmuş ve oluşmaya devam etmektedir. Bölgede yapılan çalışmalarda, yıkıcı deprem olmaksızın, uzunlukları 300 metre ile 2 km; doğrultuları ise K15°D ile K70°D arasında değişen hareketler ve yarılmalar şeklinde gelişen kademeli yüzey deformasyonları haritalanmıştır. Yerleşim alanı içerisinde haritalanan yüzey deformasyonlarının en kuzeyde olanı Bolvadin Fayı'nın güneybatıdaki devamı niteliğindedir. Yapılan jeolojik ve jeomorfolojik analizler yüzey faylanmaları boyunca, güneydoğuda yer alan bloğun 10-40 cm arasında düştüğüne işaret etmektedir. Yapılan jeodezik analizler bölgedeki son dört yıllık düşey yerdeğiştirme hızının 7,1 cm/yıl olduğunu göstermektedir. Bu sonuçlar, Bolvadin Fayı boyunca gelişen yüzey deformasyonlarının önemli bir nedeninin, yeraltı su seviyesi düşüşüyle ilgili olduğunu göstermektedir. Söz konusu yüzey deformasyonlarının oluşumuna, bölge tektoniğinin katkısını ortaya koymak için hendek tabanlı paleosismolojik çalışmalara ihtiyaç vardır.

“…The information was downloaded from the National Geographical Information Centre of the Spanish National Geographic Institute [35]. The ArcGis 10.8 [36] and IDRISI TerrSet 18 software packages [37] were also used. Data from 2000 to 2018 were used to obtain land use and land cover changes, while data from 2012 were used to calibrate the processes of arable land abandonment and rewilding via the random selection of different parcels of land, so preventing them from being confused with fallow land.…”

Depopulation often leads to the abandonment of agricultural land and the resulting process of afforestation and reforestation. In this paper, we study the land use changes between 2000 and 2018 in two Spanish provinces, Soria and Teruel. The provinces chosen as case studies are of particular interest because they have some of the lowest population densities in Europe and continue to suffer depopulation processes that have been ongoing since the mid-20th century. The reasons for this are not immediately clear given that unlike other European regions with similar population density values, for example in Northern Scandinavia, they are not exposed to extreme climatic conditions, nor are they located in isolated mountain regions. Using the CORINE Land Cover database, we observed that in both provinces, there has been an expansion in shrub and forest land uses and a decline in agriculture due largely to the fact that certain areas have been abandoned by their inhabitants, although in other parts of these provinces, the amount of land used for agriculture has increased. Urban growth over this period has been minimal. In the coming years, it seems likely that the population of these areas will continue to fall, given that the policies carried out over decades to try to revert this trend have not been successful.

“…According to previous studies on similar deformations around the word, two types of ground failure are defined; "surface faults" and "earth fissures" (Holzer, 1980(Holzer, , 1984Pewe, 1990;Holzer and Galloway, 2005;Pacheco-Martínez et al, 2013;Hernández-Madrigal et al, 2014). Surface faults are shear failures that occur along pre-existing faults, and earth fissures are tensile failures that are mostly observed parallel to the stream.…”

In the actively deforming region of western Anatolia, crustal deformation is accommodated by destructive earthquakes and a variety of aseismic events. In this study, we investigated the 2016–2017 aseismic sequence located in the Bolvadin Fault, one of the segments of the Akşehir-Simav Fault System of western Anatolia by analysing surface deformation derived from detailed geological mapping. Our findings suggest that surface deformation in the Bolvadin Fault is accommodated by aseismic episodes. During the field studies in the Bolvadin area, progressive surface deformations, such as surface faults and earth fissures with a length of 800 meters to 3 kilometres and strike of N15°E to N70°E were mapped on a 1/5000 scale. Furthermore, a levelling network was established to calculate the vertical displacements and deformation rate along the surface deformations. Precision level measurements were undertaken in 2016 and 2017. On the routes to the NW of the Bolvadin settlement, a vertical deformation rate of 30 mm/yr was detected in the period of 2016–2017, and a large deformation rate of 40 mm/yr was detected in the same period.
