DETECTION OF P- AND S-WAVE ARRIVAL TIMES USING THE DISCRETE WAVELET TRANSFORM IN REAL SEISMOGRAMS

Arman, Hasan; Çerezci, Osman (KING FAHD UNIV PETROLEUM MINERALS, 2009)

In this study, a novel solution based on discrete wavelet transform is introduced to determine P- and S-wave arrival times. An algorithm is developed based on changes in frequencies and energy in high frequency bands. ...
Frequency-energy variability characterization of local real-time noisy seismic records

Arman, Hasan; Çerezci, Osman (WORLD SCIENTIFIC PUBL CO PTE LTD, 2008)

In this study, we have presented a new approach to separate noisy components and to characterize frequency-energy variability for local real-time noisy earthquakes where epicentral distance is 0-10 degrees. This approach ...

O. H. Colak; T. C. Destici; S. Ozen; Arman, Hasan; Çerezci, Osman; C Ardil (WORLD ACAD SCI, ENG & TECH-WASET, 2006)

The wavelet transform is one of the most important method used in signal processing. In this study, we have introduced frequency-energy characteristics of local earthquakes using discrete wavelet transform. Frequency-energy ...
