San Francisco
2 documented theories filed under this subject.
- The "Chinese" Underground RailwayThis theory claimed that San Francisco’s Chinatown was connected to an elaborate underground railway or tunnel network that ultimately reached ships, coastal escape routes, or, in its most fantastic version, a route “to China.” The theory emerged from anti-Chinese prejudice, tourism mythmaking, and longstanding fascination with hidden tunnel lore. It attached itself to the fact that San Francisco’s Chinatown was widely exoticized by outsiders and repeatedly misrepresented as a secret city beneath the visible one.
- The "San Francisco Earthquake" (1906) Dynamite PlotThis theory claimed that explosives used after the 1906 San Francisco earthquake were not primarily intended to stop the fire, but were used to destroy buildings in ways that benefited insurers, owners, speculators, or officials. The rumor grew from a real historical fact: authorities and troops did use dynamite to create firebreaks, and those efforts often worsened the destruction. Because insurance coverage treated fire and earthquake damage differently, the disaster created a lasting environment of suspicion around motive, classification, and profit.
