Re: deep water = less ejecta?

Not qualitatively, according to my understanding; the heat of the vapor 
obviously dissipates quickly relative to liquid due in part to the many point 
sources involved. Also as the the vapor condenses it extracts heat from the 
atmosphere. 

A jet of steam is devastating at close range, but cools quickly, whereas a jet 
of liquid water (or molten rock) will hold it's heat much further/longer...
