Description	The western part of the Corinth Gulf attracts attention clue to its seismically active fault system and considerable seismic hazard. A moderate size earthquake occurred close to the town of Efpalio on January 18, 2010, followed by a sequence of smaller earthquakes. In the present paper we use this sequence to derive a local structural model for the region in the vicinity of Efpalio. The model is based on the minimization of travel-time residuals. In particular, we used arrival times from 51 selected events recorded 017 January 19 and 20 by at least 5 stations at epicentral distances less than about 25 kin. A variant of the method of conjugate gradients has been used for this purpose. In comparison with several previous models, the new model is characterized by higher velocities to a depth of about 8 km. The velocity ratio in the model is upsilon(P)/upsilon(S) = 1.83. The hypocentres of the selected earthquakes lay at depths between about 5 and 9 km, but their distribution is rather irregular.
