The underground structures that are mandated for this community are all earthquake proof and tornado proof and virtually fireproof, so that does not bother me too much. I would not want to be on the fault line but the coast is a different story. From hurricanes showing up, flooding or even tidal waves, I'm sticking to above 1200 feet. Less humidity and prettier scenery. The hills give character to the land and also allow the hillside building spots for the perfect underground structure! So far, that sweet spot in northern georgia, western north carolina, eastern tennessee and western virginia come about as close to the perfect spot as I can find. I know there are some great spots up north but I just am not acclimated to the cold!
Thanks
