Seismic Structure of Local Crustal Earthquakes beneath the Zipingpu Reservoir of Longmenshan Fault Zone

Figure 3

Distribution of the local earthquakes used in the present study. Ellipses denote earthquake epicenters given by the double-difference relocation. Solid triangles are all stations (temporary + permanent) used in the relocation and tomography inversion. The plus symbols present the area of the tomography grids and that of velocity inversion as shown in Figure 5. The others are the same as in Figure 1.
