**6. Locating seismic events**

In the following we consider amplitude and travel time data (PGV, Tp, Tsp) of one particular seismic event (earthquake) after the application of station

corrections (SA, SDp, SDsp). We search for the hypocenter within a 3D grid, centered at the maximum PGV or minimum travel time station. In our special case the grid extends from �20 km to +20 km in W-E and S-N with a grid spacing of 0.5 km around this center. We consider 17 hypocenter depth levels from �16 km to 0 km. The indices of the grid in the east, north and upward directions are (k, l, m).
