at 200 mph, nothing stands.
About the only things that can survive are completely underground shelters, or shelters above ground built of solid concrete, with earth walls built up at no more than 20 degree angle with grass well embedded into dirt..
or of course, a nuc sub 150 feet below it. Quiet as a church.
Methinks you'd want it at 450 feet.
When waves can reach +100ft, I think you'll get tossed around at -150ft.
