SAN FRANCISCO 1906: The Earthquake That Finished a City With Fire

At 5:12 A.M. on April 18, 1906, the northern San Andreas Fault ruptured for 296 miles in 47 seconds. What followed was not one catastrophe but three: an earthquake that disarmed the city, a firestorm that killed it, and a decision made in a private boardroom to rename the disaster for the insurance ledgers. This is the story of what actually destroyed San Francisco, and of the report in Sacramento that could have prevented all of it.
