Abstract

Nowadays, time-frequency analysis of earthquake records using wavelet transform is widely employed in earthquake engineering and engineering seismology. Wavelet transform is one of the appropriate methods in investigating frequency content of signal in time domain. In this study, an earthquake occurred in Japan on 06 Oct. 2000 with a 7.3 magnitude is investigated. 303 seismometers recorded this event and two of these records, nearest and farthest to the epicenter, are evaluated through continue wavelet transforms (CWT). CWTs of east-west component of these two records are obtained and its frequency-time analysis is discussed.

Özet

Son yıllarda, deprem mühendisliği ve mühendislik sismolojisinde, deprem kayıtlarının zaman-frekans analizlerinin dalgacık dönüşümü ile yorumlanması giderek yaygınlaşmyıtır. Dalgacık dönüşümü incelenen sinyalin frekans içeriğinin zamanla değişimini incelemek için en uygun metotlardan biridir. Bu çalışmada, Japonya`da 06 Ekim 2000 tarihinde meydana gelen 7.3 büyüklüğünde ve 303 sismometre tarafından kayyt edilen deprem kayıtları arasında deprem odak noktasına en yakın, yüksek frekanslı bileşenlerin fazla, ve en uzak, alçak frekanslı bileşenleri hakim olduğu, iki ivme kaydının doğu batı bileşenlerinin sürekli dalgacık dönüşümleri elde edilmiş ve bu yöntemin frekans-zaman analizleri yorumlanmyıştır.
