Abstract :In this study, seismic activity in Trabzon and its vicinity is investigated and natural and artificial seismic activities are discriminated. Total of 125 digital vertical velocity seismograms of 65 seismic events with Md≤3.0 duration magnitude from earthquake catalog between 2006 to 2007 recorded by Trabzon insert ignore into journalissuearticles values(KTUT);, Espiye insert ignore into journalissuearticles values(ESPY);, Pazar insert ignore into journalissuearticles values(PZAR); broadband stations operated by Karadeniz Technical University were used in the study. The maximum S-wave and maximum P-wave amplitude ratio insert ignore into journalissuearticles values(S/P); of vertical velocity seismograms and power ratio insert ignore into journalissuearticles values(complexity, C); and spectral ratio insert ignore into journalissuearticles values(SR); were calculated. The earthquakes and the quarry blasts are discriminated by using the linear discriminant function on the graphics of S/P amp ratio to log S and C to Sr. At the end of this study 43 out of 65 events insert ignore into journalissuearticles values(66%); are determined as quarry blasts and 22 insert ignore into journalissuearticles values(34%); are as earthquakes.
