I  continually maintain that mother nature will keep seeking ways to right  the imbalance  the human plague of consumption is causing this planet. 
It is interesting that this 'silent' event comes at a time of  increasing global natural disturbances such as the explosion of  Eyjafjallajokull, unusual weather disturbances, increasing seismic  activity in unusual places and the blowout and subsequent capping of the  oil well in the Gulf of Mexico. 
This may not be a fortuitous event, but natures way of addressing  the damage we are doing to the ecological stability (internally and  externally) of this planet - our home. 
It seems as though we are now living on a giant pressure cooker  that is about to blow off excess forces that we cannot foresee, do not  understand and cannot stop. 
If this event happens every 300-900 years and the last was  supposedly in 1700, we are already within the window of opportunity,  or miss-opportunity (if that's the word?). Maybe now is the time to take  your long service leave!
