The seismic structure beneath Kamchatka and, in particular, beneath the Kluchevskoy volcano group, has been investigated in a number of tomographic studies on different scales. Regional tomographic models based on body and surface wave data [e.g., Levin et al.,2002 ; Gorbatov et al.,2001;lees et al., 2007a; Koulakov et al.,2011] revealed a rather clear shape of the subducting Pacific plate beneath Kamchatka.
