By the end of 1849 at least 600 ships were floating in Yerba Buena Cove (the current site of San Francisco's financial district). Ex-sailing vessels were used as jails, nightclubs and even hotels. Most of the ships were eventually buried in the cove where skyscrapers like the TransAmerica Pyramid and One Maritime Plaza now stand.
The Golden Gate bridge has crisis telephones because people are always out on the bridge trying to jump off.
Just about every grave in San Francisco was dug up in 1914 and moved down to Colma. No one is buried in San Francisco anymore. The only two remaining cemeteries are next to Mission Dolores Church and in the Presidio.
Vermont street over between McKinley and 22nd Street is just as curvy as Lombard Street.
The two steepest streets in San Francisco are 22nd Street between Church and Vicksburg, and Filbert between Hyde and Leavenworth. Both streets have a 31.5% grade and are one-way; down only. The steepest street you can actually drive up is Jones between Union and Filbert with a 29% grade.
The 1906 earthquake registered 8.25 on the Richter scale, it was the largest earthquake in the 48 states, but still not as big as 6 occurring in Alaska in 1899(two), 1900, 1903, 1938 and 1964 (the last registered at a magnitude of 9.2)
The Marina District is probably the most dangerous place to be in San Francisco during an earthquake. When the earthquake in 1906 struck, it decimated the Marina. They used the rubble from the fallen buildings to fill in lagoons and part of the bay and then apartment buildings and homes were built on top of this not-so-solid land. During the 15 seconds of the 1989 earthquake, the ground rippled and buildings along Beach Street near the Palace of Fine Arts collapsed with people inside. You probably don't want to hang out with the yuppy fucks who live there anyway.
