The hot pumice clasts rapidly absorb water and sink, forming density currents that flow across the seafloor.

    In other very violent eruptions like Krakatoa, water plays a large part in the power of the eruption. When super-heated by magma, the steam expands explosively giving many volcanoes their power.

    Krakatoa was so powerful that the island itself was completely destroyed and the eruption was heard over 2,000 miles away. It caused a dip in global temperatures and dramatic sunsets over the next year.

    "...reflecting the important influence of confining pressure and the higher heat capacity, density, and viscosity of water compared to air."
