Fig. 2From: Three-dimensional S-wave attenuation structure in and around source area of the 2018 Hokkaido Eastern Iburi Earthquake, JapanS-wave attenuation (Qs) structures at depths of 0–90 km in and around Hokkaido, Japan. The frequency, \(f\), is 10 Hz. The well-resolved area, where the restoration index, RI, is greater than 0.001. White circles denote the earthquakes used in this study. Black triangles are volcanoesBack to article page
