Abstract
The Gulf of Corinth is one of the most active tectonic rifts around the world. Data used in the present study are obtained by the four digital stations of the Cornet Network which was installed in 1995 around the Eastern Gulf of Corinth. A velocity model was calculated, while the majority of local events were located within the Gulf of Corinth. Main scope of the study is the determination of a reliable earthquake magnitude. Concerning the duration magnitude Mo, a multiple linear regression technique was developed for the determination of the constants α, β and γ with very satisfactory values of errors. The coefficient of determination (goodness of fit) R2 was found equal to 0.99. Following, the moment magnitude Mw, which is considered to be the most reliable magnitude scale, was determined. Spectral analysis was applied for the calculation of the seismic moment M0 and a seismic catalogue was created. After the determination of the moment magnitude Mw and of the duration magnitude MD for the same dataset, a relationship between them was obtained, according to which Mw is systematically larger than Mjy Relationships between these magnitudes, the local magnitude ML and the body wave magnitude mb were also obtained.
