10 km is about 33,000 feet... that's too deep to be 'suspicious.'

You have a point, but it seems that the floor at that point may be significantly lower...how can an earth quake be more shallow then the floor?...you know, maybe the star on the graph is actually hiding the real depth.

Is that too deep for a sub? or could something detonate after being dropped when it reaches a certain pressure level...just as there have been discussions about setting a switch for air pressure?
