  4. Pyroclastic density currents and local topography as seen with the conveyer model

    11 Jul 2020 | Publications

    Pyroclastic density currents (PDCs) are multiphase flows generated during explosive volcanic eruptions, and they move down the volcano, and over the surrounding topography. The flow-topography interaction can play a fundamental role in the sedimentary processes, and in the resulting deposit...
