Kuzey Anadolu Fayı Zonu'ndaki Bazı Faylarda Radon Gazı (Alpha İzi) Ölçümleri

Year 1992, Volume: 16 Issue: 1, 33 - 40, 15.05.1992

Abstract

Çalışma sırasında Kuzey Anadolu Fay Zonu içinde yer alan bazı deprem fayları ve aktif faylar ü zerinde iki değişik yöntem kullanılarak alpha izi ölçümleri yapılmıştır. Bunlardan birincisi fay izini saptamaya yarayan "kısa süreli ölçüm yöntemi", diğeri ise fay aktivitesini değerlendirmekte kullanılan"uzun süreli ölçüm yöntemi"dir. Kısa süreli ölçümlerden alpha izi ölçümlerinin sadece aktif fayların izlenmesinde değil, aynı zamanda deprem faylarının izlenmesinde de yararlı olduğu, hatta bölgedeki aktif olmayan fayların da bir miktar radon gazı içerdiği sonucu elde edilmiştir. Uzun süreli ölçümlerden ise gaz çıkışındaki mevsimsel değişiklikler izlenmeye çalışılmış, bunun başlıca sıcaklığa bağlı olduğu anlaşılmıştır. Mekece yöresinde, Kuzey Anadolu Fayı'nda her iki yöntemle de elde edilen alpha izi yoğunluğu normalin çok üzerindedir. Dahası, uzun süreli ölçüm yöntemiyle bölgede elde edilen en yüksek değer kış aylarına rastlamaktadır. Bu gerçekler fayın bu kesiminde aktivitenin çok yüksek olduğuna işaret eder.

Alpha Track Measurements on Some Faults Along the North Anatolian Fault

Year 1992, Volume: 16 Issue: 1, 33 - 40, 15.05.1992

Abstract

Two kinds of methods of alpha track measurement were carried out for earthquake and active faults along the North Anatolian Fault. One of them is the short term other is the continuous measurement method for evaluating the faulty activity. The results by the short term method show that alpha track measurement is useful to detect even in the regions reproducibility of the alpha track measurement if measured in nearly the same temperature condition. The results by the continuous measurement method show mainly. In both two methods, however, the underground water supply must be taken into consideration before evaluation. In Mekece region, east of İznik, the seismic gap area of one branch of the North Anatolian Fault Zone, the maximum alpha track density obtained by both methods is abnormally high. Furthermore, the result by the long term measuring method shows the highest value in winter. These facts indicate that this branch of the North Anatolian Faults is very active.
