Agree!  Most of the time it's wonderful to be able to go to bed and wake up  with the sounds of waves gently coming on shore, but it's a chance you take.  It's the same for people who buy homes at the base of a mountain.  Boulders will roll down from time to time!  For people who purchase homes on the hillside, look out for sliding foundations!  No matter where you buy, there's something that can happen, but if you want to minimize the possibilities, you might want to stay away from the ocean and mountains.
