Article Tsunami Awareness: A Case Study Of Hasköy, Beyoğlu, İstanbul(Afet ve Acil Durum Yönetimi Başkanlığı (AFAD), 2025) Taskin, H.; Gunaydin, D.H.; Yücel, G.An earthquake-triggered tsunami, originating from seismic activity in seas and oceans, poses a significant threat to coastal settlements within its impact zone. As part of risk reduction efforts, enhancing public awareness of tsunamis is crucial for mitigating potential disaster-related damages. Accordingly, this study emphasizes the importance of tsunami awareness initiatives by assessing the pre-disaster knowledge levels of the community. The study aims to measure the tsunami-related knowledge and awareness levels of residents in a settlement exposed to tsunami hazards. In this qualitative research, data were collected through semi-structured interviews conducted with business owners and employees in a purposively selected settlement. The study was carried out in the Piripaşa neighborhood of the Hasköy district in Istanbul’s Beyoğlu region, specifically within the coastal area parallel to the shoreline of the Golden Horn. Data were obtained from 22 active commercial enterprises out of 50 located along this coastal road. During the interviews, five key questions were posed to assess the respondents’ basic knowledge of tsunami awareness. The questionnaire also included images of tsunami evacuation route signs. The questions covered demographic characteristics, business activity sector, knowledge of tsunami hazards, awareness of the region’s tsunami risk, familiarity with tsunami evacuation procedures, and knowledge of relevant institutions and organizations involved in tsunami preparedness. The findings of the study indicate that the majority of the surveyed enterprises predominantly operate within the service sector. Furthermore, the results reveal a notably low level of awareness among participants regarding tsunami hazards, as well as limited knowledge of appropriate response behaviors during such events. While 50% of participants believe that the region is not at risk of tsunamis, 59% reported being aware of tsunami warning signs, which is a notable observation. Enhancing awareness of tsunami hazards and the region’s tsunami risk level is both essential and a priority. © (2025), (Afet ve Acil Durum Yonetimi Baskanligi (AFAD)).

Bu iki değere göre, 81 Türk kentinin 10 kümede gruplandığı görülmüştür. Normal dağılımından dolayı lakunarite katsayılarının dağılımı ki-kare uyum iyiliği testini geçerken; iki modlu bir dağılımda olduğu için fraktal boyutların dağılımı bu testi geçememiştir. Elde edilen sonuçlardan, fraktal boyut ile lakunarite arasında zayıf, negatif, anlamlı (% 5 anlamlılık düzeyinde) bir korelasyon olduğu anlaşılmıştır; fraktal boyut ile nüfus arasında zayıf, pozitif anlamlı (% 1 anlamlılık düzeyinde) bir ilişki; ayrıca fraktal boyut ile il bazında kişi başına gayri safi yurtiçi hasıla arasında orta düzeyde, pozitif anlamlı (% 1 anlamlılık düzeyinde) bir ilişki bulunmuştur. Lakunarite ve nüfus arasında anlamlı bir ilişki bulunamamıştır. “Genellikle büyük şehirlerin birbirine benzediği” belirtilmiş olsa da; fraktal boyutlar ve lakunarite katsayıları kullanılarak çok değişkenli bağlamda Türkiye şehirlerinin benzerliklerini incelediğimizde küçük şehirlerin daha benzer olduğu görülmüştür.Article Citation - WoS: 1Citation - Scopus: 2Determining the Effect of Urbanization on the Vegetation of Gurun District (sivas) Based on Biotope Mapping and Vegetation Analysis(Istanbul Univ-cerrahapasa, 2020) Bozkurt, Selvinaz Gulcin; Akkemik, Unal; Kose, NesibeUrbanization is one of the strongest negative effects on vegetational change within and around a city. In this study, it is aimed to determine the flora and vegetational changes within and around the city based on the identification and mapping of the biotopes which show differences in terms of ecologic factors met in Gurun district center and its vicinity and which are suitable for Corine biotope classification. First, 13 main biotope types are classified. In the biotopes, total 666 plant taxa were identified, 84 of which were endemic. Vegetation of the biotopes was determined, and then similarity levels of main biotopes are calculated according to the similarity coefficient method of Sorensen. Accordingly, while the similar areas are health facilities and agricultural areas the most different ones are parks and sports areas and drainage areas. The results emphasize the similarity levels of vegetation in biotopes and the negative effect of human intervention in the study area. As a result, with its rich natural structure, vegetation covers and endemism rate, the district of Gurun has significant natural biotopes and it is suggested that biotope classification should be considered in determining vegetation change and urban planning.
