Fig. 3From: Stress and pore fluid pressure control of seismicity rate changes following the 2016 Kumamoto earthquake, JapanEarthquake focal mechanism data for the preseismic period of the Kumamoto earthquake sequence. Focal mechanism data are represented with lower hemisphere projections of focal spheres. The color scales denote hypocentral depths. The star, the black dashed lines, and the grey lines are the same as in Fig. 2. The black and red dashed lines show the model region for the background stress field and pore fluid pressure field and the study region for detailed investigation, respectivelyBack to article page
