摘要
A moderate size earthquake occurred close to the town of Efpalio in the Corinth Gulf region on January 18, 2010. In the present paper, we have used this earthquake to study the dispersion of short-period Love waves along nine paths in a broader vicinity of the Corinth Gulf. The observed group velocities require very low S-wave velocities in the uppermost 2-km depth. This structural feature differs distinctly from most previous models that were derived from arrival times of body waves in the region. Moreover, it was recognized that the observed group velocities were relatively low for western paths, and medium velocities were observed in the central part of the region, and the highest velocities in its eastern part.
