Yearly inversion results from 2001 to 2008 for P- and S-velocity
anomalies and Vp/Vs ratio are presented in Figs. 5 to 7 along a vertical
section that passes through the active Kluchevskoy and Bezymianny
volcanoes and the dormant Zimina and Kamen volcanoes. We also present
Vp and Vs anomalies and Vp/Vs ratio for yearly time windows in horizontal
sections at 12 km and 30 km depth in the auxiliary materials
(Figs. A2 and A3). The distributions of Vp/Vs ratio in the same vertical
section as in Figs. 5–7 for the entire series of 40 overlapping time windows
(one year with the step of three months) are presented in auxiliary
materials, Fig. A4.
