Atlantis dropped in to the ocean,
San Francisco is well known to be at high risk of dropping in to the ocean.
San Francisco is very advanced, new products tend to be released here first because of the large amount of tourists and diversity of it's residents to see how well the products will sell. Even billboard advertisements have to meet high requirements, so that they match the cities high standards. If a time traveler went back in time after seeing San Francisco drop in to the ocean, that is exactly how he would describe it. San Francisco is Atlantis.
The fact that an earth quake strong enough to drop San Francisco in to the ocean is very possible and will inevitably happen is commonly known among every person that lives in San Francisco. It is also known among a large amount of people that have never even been to San Francisco. Every resident of San Francisco is very frequently warned of this risk by experts, their own government sponsored resources, and other residents.
