Nature bursting bubbles…

Volcanos: One of Nature’s least subtle means of showing her pure strength. Their power to destruct and create left people in fear and admiration. Starting rivers of lava and showers of ashes, reshaping whole landscapes but also making the surrounding land fertile for years and housing gold and gems makes the fire-breathing mountains so fascinating. But thousand degrees hot discharge and deafening explosions can turn into small bubbles, quietly bursting upon touching air, in mere minutes. That is, if the volcano lies under water…

…Below is a soundclip of volcanic explosions from the erupting seafloor volcano NW Rota1 in the Mariannas Arc. The shock waves were visible and are accompanied by explosive blast sounds in the audio link from a hydrophone 20m away. This eruption is occurring under 500m of seawater adding to the confining pressure at the vent, and still large blocks and huge bubbles are bursting as they are expelled from the vent.
