    Co-postseismic hydrogeochemical anomalies in a volcanic environment by P. F. Biagi, O. Molchanov, R. Piccolo, A. Minafra, A. Ermini, V. Capozzi, Y. M. Khatkevich, E. I. Gordeev

    Published 2003-01-01
    “…We advance the hypothesis that this pumping could be the response of the viscoelastic underground medium of the Koryakskiy volcano to seismic waves. So, sometimes, the supply of elastic energy of the earthquakes may provide the trigger to a catastrophic nucleation of bubbles of this material producing a new melt with a lower density which will tend to expand and cause a pressure increase. …”
