Fig. 9From: Estimation of shallow S-wave velocity structure using microtremor array exploration at temporary strong motion observation stations for aftershocks of the 2016 Kumamoto earthquake a Comparison of observed phase velocity curves (circles) with those calculated for the model at KMMH16 (blue), for the shallow V S model determined from the observed microtremors (gray), and for the replacement V S model in the shallow part of the V S structure determined from the observed microtremors (red). b Same comparison as in (a) for the H/VBack to article page
