Erratum to Velocity Structure of the Tibetan Lithosphere: Constraints from P-Wave Travel Times of Regional Earthquakes by Jessica D. Griffin, Robert L. Nowack, Wang-Ping Chen, and Tai-Lin Tseng
In Figure 5 of Griffin et al. (2011), the subplots of the figure were mislabeled. The labels should indicate a shallow-
(a)
ing of the Moho depth and a decrease in Pn velocities to the north. The corrected Figure 5 is shown here.

Figure 5. The observed P-wave travel times (circles) for events (a) L1e, (b) L1a, (c) L1i, (d) L1j, (e) L1k, and (f) E3b. These sources are located at regional distances to the Hi-CLIMB array, and Pn travel times for these events were used to constrain the P-wave velocity structure of the upper mantle for the Tibetan Plateau region. All travel times are reduced by 8:0 km=s and plotted with respect to the minimum recorded travel time. The lines and crosses in each figure show the calculated travel times using the 3D regional velocity model found in this study and shown in figures 6 and 7 of Griffin et al. (2011). The horizontal bars highlight the locations of the transition for shoaling of the Moho and a northward decrease in Pn velocities. 454
