Timeline — Great San Francisco Earthquake —
April 18 – 23, 1906 This timeline is excerpted from Gladys Hansen’s “Chronology of the Great Earthquake, and the 1906-1907 Graft Investigations.”
San Francisco was wrecked by a Great Earthquake at 5:13 a.m., and then destroyed by the seventh Great Fire that burned for four days. Hundreds, perhaps thousands of trapped persons died when South-of-Market tenements collapsed as the ground liquefied beneath them. Most of those buildings immediately caught fire, and trapped victims could not be rescued. Reevaluation of the 1906 data, during the 1980s, placed the total earthquake death toll at more than 3,000 from all causes. Damage was estimated at $500,000,000 in 1906 dollars.
Fire Chief Engineer Dennis T. Sullivan was mortally wounded when the dome of the California Theatre and hotel crashed through the fire station in which he was living at 410-412 Bush St. Acting Chief Engineer John Dougherty commanded fire operations.
The earthquake shock was felt from Coos Bay, Oregon, to Los Angeles, and as far east as central Nevada, an area of about 375,000 square miles, approximately half of which was in the Pacific Ocean. The region of destructive effect extended from the southern part of Fresno County to Eureka, about 400 miles, and for a distance of 25 to 30 miles on either side of the fault zone. The distribution of intensity within the region of destruction was uneven. Of course, all structures standing on or crossing the rift were destroyed or badly damaged. Many trees standing near the fault were either uprooted or broken off. Perhaps the most marked destruction of trees was near Loma Prieta in Santa Cruz County, where, according to Dr. John C. Branner of Stanford University, “The forest looked as though a swath had been cut through it two hundred feet in width.” In little less than a mile he counted 345 earthquake cracks running in all directions.
U.S. Post Office at Seventh and Mission sts. was dreadfully damaged by the earthquake. Assistant to the Postmaster Burke said, “walls had been thrown into the middle of various rooms, destroying furniture and covering everything with dust.

Father Ricard at the University of Santa Clara wrote to the “San Jose Mercury”.
The earthquake period is gone. Once the pent up forces of nature have had a vent, nothing of a serious nature need be apprehended. At the most a succession of minor shocks may be felt and that’s all. It is not unreasonable, therefore, for people to continue in dread of a new destructive temblor. People should fearlessly go to work and repair mischief done and sleep quietly at night anywhere at all, especially in wooden frame. Never mind foreboders of evil: they do not know what they are talking about. Seismometry is in its infancy and those therefore who venture out with predictions of future earthquakes when the main shock has taken place ought to be arrested as disturbers of the peace.
