Fig. 3From: Heterogeneous mantle anisotropy and fluid upwelling: implication for generation of the 1891 Nobi earthquakePolarization data from the research area are shown in four geographic regions (a–d). The polarization azimuths of the maximum-velocity phase and the time delay between the maximum- and minimum-velocity phases are indicated by the direction and length of each bar, respectively. Bars are overlain on locations of seismic stations. Stars denote epicenters of deep earthquakesBack to article page
