The true story of how a seismic shock sparked a devastating and preventable firestorm At 5:12 am on April 18, 1906, a 7.9 magnitude earthquake struck San Francisco, catching most of the city asleep. For approximately forty-eight seconds, shock waves buckled streets, shattered water mains, collapsed buildings, crushed hundreds of residents to death, and trapped many alive. Fires ignited and blazed through dry wooden ruins and grew into a firestorm. For the next three days, flames devoured collapsed ruins, killed trapped survivors, and destroyed what was then the largest city in the American West. Matthew Davenport draws on letters, diaries, unpublished memoirs, and previously unearthed archival records, as well as interviews with engineers and geologists, to combine history and science to tell the dramatic true story of one of the greatest disasters in American history. Meticulously researched and gracefully written, The Longest Minute is both a harrowing chronicle of devastation and the portrait of a city’s resilience in the burning aftermath of greed and folly.
