Figure 5From: Stress state in the upper crust around the source region of the 1891 Nobi earthquake through shear wave polarization anisotropyRelation between time delay and focal depth. Plot of focal depth versus time delay, δt, of each event (black circles). The error bar shows a confidence interval of 95%. Open circles show the average time delay for events shallower and deeper than 12.5 km and error bars the standard deviation.Back to article page
