And there is some question about whether massive quantities of water can act as a lubricant or can build up steam/pressure on a fault causing a quake. I've seen that theorized anyway.
Yeah, for example when the high tide fills up a bay it adds a massive weightload on a fault that might sit there.
I saw the Mayor of N.O. speak yesterday and he made it clear that he didnt have the authority to order a mandatory evacuation, he said "That has to come from someone higher than me." I had the strong feeling he was begging people to read between the lines and leave. His eyes looked haunted to me--they still do.
Stadium effect is the wind tunnel created by winds passing around high rise buildings that concentrate around a shorter structure (I believe).
