Abstract
Recent seismic activity in Gokova region can be characterized by earthquake swarms, which mostly occured during 2004 and 2005. This activity was continued for seven months and 1558 seismic events were recorded at this period. The b-value of Guthenberg-Richter relation is investigated for this earthquake swarm and a high b-value is found as 1.73±0.08 using the maximum likelihood method. In this study, seismogram and spectrum characteristics of the earthquake events in Gokova region are analyzed. Accordingly, low frequency waveform and spectrum are obtained for shallow events whereas deeper events are observed to be characterized by high frequency waveform and spectrum. Apart from direct P and S waves, we noticed the presence of strong reflection phase on the seismograms. These reflected phases come from ~17 to 18 km depth in Gokova region. Key words: Gokova region, reflected phase, earthquake swarm.
