Fig. 15From: Directionally dependent horizontal-to-vertical spectral ratios of microtremors at Onahama, Fukushima, JapanComparison of the observed MHVRs (solid blue and red lines) with the numerical MHVRs (broken blue and red lines) for point A6. The numerical MHVRs show the same directional dependence as the observed MHVRsBack to article page
