Rapid changes in magma storage beneath the Klyuchevskoy group of volcanoes inferred from time-dependent seismic tomography

► We present time-dependent tomographic model beneath the Kluchevskoy Volcano Group ► We found one mantle channel with high Vp/Vs ratio feeding the Kluchevskoy volcanoes ► Fast variations of Vp/Vs ratio in the crust are due to fracturing and fluid transport.
