Fig. 1From: Heterogeneous mantle anisotropy and fluid upwelling: implication for generation of the 1891 Nobi earthquakeLocation map of seismic stations and earthquakes. Red circles denote epicenters of deep earthquakes. Black triangles indicate permanent seismic stations operated by Hi-net and universities. Blue squares indicate temporary seismic stations operated during this study. The lightly shaded area denotes the NKTZ. Yellow lines are faults that ruptured during the 1891 Nobi earthquake. The location of the research area (black square) is shown in the inset Back to article page
