1 Erratum to: Earthq Sci (2014) 27(5):567–576 DOI 10.1007/s11589-014-0091-y

The original version of this article contained an omission of Acknowledgments section. The corrected version appears in this erratum.

In addition, Fig. 3 should be updated by new one as below.

Fig. 3

Shear wave section along the tectonic equator (TE) and perturbed path (TE-pert) of the Earth. Generalized asymmetry is evident across oceanic ridges: lithosphere (0–100 km) on the western side of the rift has a higher velocity than on the eastern or northeastern side, whereas the upper asthenosphere (low-velocity layer, 100–200 km) has a slower velocity on the western side with respect to the conjugate counterpart. Red lines correspond to elements of the Eastern Pacific, Mid-Atlantic, and Indian Ridges. Radial anisotropy sections shown in the lower panels are without crust, since the crust is assumed to be isotropic. V _S is taken here as average of V _SV and V _SH (modified from Panza et al. 2010). Along the TE-pert, which is not a great circle, a ubiquitous LVZ, about 1000-km-wide and 100-km-thick, occurs in the asthenosphere, where the most mobile mantle (LVZ) is located (decoupling layer). The arrows indicate the possible relative motion
