Spatial distribution of focal mechanisms obtained in this study. An additional data file shows these focal mechanisms in more detail (see Additional file 1). Mechanisms of quality A, B, and C are plotted. All diagrams are equal area projections on the lower hemisphere of the focal sphere. Colored areas show compressional quadrants. Bold lines are the surface traces of the seismic fault ruptured by the 1891 Nobi earthquake. Thin lines are other active faults
