This appears to be what happens when you build on a cliff right next to the ocean.
I eventually settled on the San Francisco Peninsula. Every few years, some big storms roar off the Pacific and more houses in San Mateo County fall into the ocean. People lose not only their house, but their land, too. Imagine that your entire land is gone, just ceases to exist!
But people made that choice knowing that the ocean and erosion are unforgiving.
