Try fitting *this* into a bedside lamp

Work reported in Nature today from a presentation at the annual AGU meeting shows easily the deepest underwater volcano ever filmed.  The eruption was filmed from a remote submarine at 1200m depth - far more than the previous 500m depth record - and shows lava bursting out onto the sea floor.  The discovery helps scientists understand how pillow basalts form and how sea floor materials are added to the oceanic crust.

Its hard to imagine how extreme that process is.  We're talking hot enough to melt lead, at pressures that would turn a styrofoam cup into a thimble!
