I do live on shaky ground. No not financially, since we sold my arents old place we are very well off. While my SO and I have had to make adjustments as I've transitioned we still seem to be pretty solid. Nor is our house on the sort of hillside that might suddenly move to another zip code, it's foundations are sunk into granite.
The problem is that granite is within easy walking distance to the San Andreas fault and sits over three subsidiary faults. The last time out section of the the San Andreas ruptured was the Fort Tejon earthquake of 1857. At a 155 years we are a bit overdue for another major quake around here. So yeah I live on some potentially very shaky ground.
