Those who rely on an understanding of the natural world via science take such things into consideration when selecting a San Clemente home location. I will say it was very entertaining during the 1982-1983 El Niño to leave our house and go look over the Capistrano Beach bluff edge, wearing full rain gear, watching science-eschewing people's homes disintegrate, then wash out to sea. Perhaps they were relying on "magic" for protection.
I grew up in Capistrano Beach, one block from the border of San Clemente, probably within walking distance of you. And I saw a picture of that house that fell down the bluff in the mudslide. Our house is a few blocks inland, so we were safe, but I've always been surprised that folks build houses near those bluffs.
In 1969, there was a long rain that caused many houses in the Shorecliffs development to shift and crack a lot. It also caused our house to sink 4 inches in the middle.
@Huss - This thread hasn't devolved; it evolved.
