Özet:

 The study area covers the Seferihisar and Çeşme districts of İzmir province and the geothermal fields in its immediate vicinity in Western Anatolia. The study area and its vicinity is a very active region in terms of earthquakes in the instrumental period, as well as a very rich region in terms of geothermal systems. These areas are Balçova, Seferihisar Cumalı, Doğanbey, Karakoç, Doğanbey Cape, Çeşme Ilıca, Şifne, Dikili-Bergama Kaynarca, Dikili, Nebiler, Bademli, Kocaoba, Paşa, Beauty, Aliağa Ilıcaburun, Çukurova, Samurlu, Reşadiye, Bayındır and Urla Gülbahçe Geothermal Fields. Most of these geothermal fields are located on active fault zones. In the study area, Mordoğan Fault, Gülbahçe Fault Zone, Seferihisar Fault and Tuzla Fault are the most important active faults of the region, extending from west to east. A large part of this region is under the risk of earthquakes today as it was in the past. It is known that approximately 320 earthquakes with a magnitude greater than M4.0 occurred in the instrumental period 1900-2021 in and around the study area and the activity is still continuing. Between the start and end dates of this study, January 2019-January 2021, approximately 190 earthquakes with a magnitude of M3.5 occurred in the area. In addition, 1 M6.8 earthquake in 1955 and 1 Mw6.9 magnitude earthquake in 2020 occurred in the region. Within the scope of this study, a two-year monitoring study was carried out from the hot water resources determined in the Karakoç and Doğanbey Seferihisar and Şifne and Ilıca Çeşme geothermal areas in the province of İzmir, revealing the relationship between the geothermal resources and active faults in the study area, and this high earthquake activity and its environmental effects were investigated.

 Çalışma alanı Batı Anadoluda, İzmir iline ait Seferihisar ve Çeşme ilçeleri ile yakın çevresinde bulunan jeotermal alanları kapsamaktadır. Çalışma alanı ve yakın civarı aletsel dönemdeki depremler açısından oldukça aktif bir bölge olduğu gibi jeotermal sistemler açısından da oldukça zengin bir bölgedir. Bu alanlar Balçova, Seferihisar Cumalı, Doğanbey, Karakoç, Doğanbey Burnu, Çeşme Ilıca, Şifne, Dikili-Bergama Kaynarca, Dikili, Nebiler, Bademli, Kocaoba, Paşa, Güzellik, Aliağa Ilıcaburun, Çukurova, Samurlu, Reşadiye, Bayındır ve Urla Gülbahçe Jeotermal Alanlarıdır. Bu jeotermal alanların çoğu da aktif fay zonları üzerinde bulunmaktadır. Çalışma alanında, batıdan doğuya doğru yaklaşık K-G uzanımlı Mordoğan Fayı, Gülbahçe Fay Zonu, Seferihisar Fayı ve Tuzla Fayı bölgenin en önemli aktif faylarıdır. Bu bölgenin büyük bölümü, geçmişte olduğu gibi günümüzde de deprem riski altında bulunmaktadır. çalışma alanı ve çevresinde aletsel dönemde 1900-2021 magnitüdü M4.0 den büyük yaklaşık 320 adet depremin meydana geldiği ve aktivitenin halen devam etmekte olduğu bilinmektedir. Bu çalışmanın başlangıç ve bitiş tarihleri olan Ocak 2019-Ocak 2021 tarihleri arasında alanda M3.5 ten büyük yaklaşık 190 adet deprem meydana gelmiştir. Ayrıca bölgede 1955 yılında 1 adet M6.8 ve 2020 yılında 1 adet Mw6.9 büyüklüğünde depremler meydana gelmiştir. Bu çalışma kapsamında İzmir ilinde Karakoç ve Doğanbey Seferihisar ile Şifne ve Ilıca Çeşme jeotermal alanlarında belirlenen sıcak su kaynaklarından yaklaşık iki yıl süren bir izleme monitoring çalışması yapılarak çalışma alanındaki jeotermal kaynaklar ile aktif fayların ilişkisi ortaya çıkarılarak bu yüksek deprem aktivitesi ile ilişkilendirilerek çevresel etkileri incelenmiştir.
