Intrinsic and Scattering Seismic Attenuation in W. Greece

Intrinsic (Q 1 i ) and scattering (Q 1 s ) attenuation parameters have been determined in the seismically active region of W. Greece, which is continuously monitored by the University of Patras microearthquake network. One hundred and twenty-three local and shallow earthquakes close to the recording stations have been used and WENNERBERG’s (1993) approach has been adopted. Results for 1 to 12 Hz range show that Q 1 i is higher than Q 1 s and coda Q values are close to Qi, indicating that coda Q can be a reasonable estimate of intrinsic Q.
