If Katrina's eye comes in right over New Orleans or a 10 or so km west, it could be the costliest disaster in US (World?) history in terms of value of lost property. I think there should have been an effort to get those people without cars out of town....has anyone looks at the engineering of the superdome? Is it engineered for 200 mph gusts?

We are running along the Cascadia subduction zone now...the swath bathymetry is showing it....there is no seafloor trench here because so much sediment comes off northern California, Oregon, Washington that it fills the trench. There was just a long linear ridge oriented parallel to the subduction zone...west of it...must be those sediments getting squeezed as the are carried above the ocean crust that is being sucked down the trench...
