    Also, the plate that has been submerged will tend to lift the plate above it
    over time (Whole mountain ranges can be created this way, i.e. the Andes).
    So the Earth will slow down again in time.  Volcanoes are not the only way
    this happens.
    
     
    
    It's hard to know where to stop, there's always more detail.  ;-)

    Clear explanation paul!  more details not explained as well:
    
    I would add that since water and rock aren't very compactable the earth will
    spin fastest when it is a perfect sphere and slowest when you have lots of
    tall mountains (think of mountains as a skater's arms - sticking them out
    slows your rotation).  This is true of underwater mountains also as they are
    much denser than the water above them.  The more an underwater volcano
    grows, the slower the earth spins, when there is a collapse, the earth
    speeds back up.

    The seabed dropped by ~9 meters, so like a dancer pulling in her arms, the
    Earth spins faster, and since in this case, she only pulled one arm in (at
    Chile), she wobbles a little bit differently.
    The same thing happened in the Banda Aceh quake.

    Anyone know anything more about this phenomena?
