1906 San Francisco Earthquake - Subsequent Fires

Subsequent Fires

As damaging as the earthquake and its aftershocks were, the fires that burned out of control afterward were even more destructive. It has been estimated that up to 90% of the total destruction was the result of the subsequent fires. Over 30 fires, caused by ruptured gas mains, destroyed approximately 25,000 buildings on 490 city blocks. One of the largest of these fires was accidentally started in a house on Hayes Street by a woman making breakfast for her family. This came to be known as the "Ham and Eggs Fire". Worst of all, many were started when firefighters, untrained in the use of dynamite, attempted to demolish buildings to create firebreaks, which resulted in the destruction of more than 50% of the buildings that would have otherwise survived. The city's Fire Chief, Dennis T. Sullivan, who would have been responsible, had died from injuries sustained in the initial quake. The dynamited buildings themselves often caught fire. In all, the fires burned for four days and nights.

Due to a widespread practice by insurers to indemnify San Francisco properties from fire, but not earthquake damage, most of the destruction in the city was blamed on the fires. Some property owners deliberately set fire to damaged properties, in order to claim them on their insurance. Capt. Leonard D. Wildman of the U.S. Army Signal Corps reported that he "was stopped by a fireman who told me that people in that neighborhood were firing their houses… they were told that they would not get their insurance on buildings damaged by the earthquake unless they were damaged by fire."

As water mains were also broken, the city fire department had few resources with which to fight the fires. Several fires in the downtown area merged to become one giant inferno. Brigadier General Frederick Funston, commander of the Presidio of San Francisco and a resident of San Francisco, tried to bring the fire under control by detonating blocks of buildings around the fire to create firebreaks with all sorts of means, ranging from black powder and dynamite to even artillery barrages. Often the explosions set the ruins on fire or helped spread it.

One landmark building lost in the fire was the Palace Hotel, subsequently rebuilt, which had many famous visitors, including royalty and celebrated performers. It was constructed in 1875 primarily financed by Bank of California co-founder William Ralston, the "man who built San Francisco." In April 1906, the tenor Enrico Caruso and members of the Metropolitan Opera Company came to San Francisco to give a series of performances at the Grand Opera House. The night after Caruso's performance in Carmen, the tenor was awakened in the early morning in his Palace Hotel suite by a strong jolt. Clutching an autographed photo of President Theodore Roosevelt, Caruso made an effort to get out of the city, first by boat and then by train, and vowed never to return to San Francisco. Caruso died in 1921, having remained true to his word. The Metropolitan Opera Company lost all of its traveling sets and costumes in the earthquake and ensuing fires.

Some of the greatest losses from fire were in scientific laboratories. Alice Eastwood, the Curator of Botany at the California Academy of Sciences in San Francisco, is credited with saving nearly 1,500 specimens, including the entire type specimen collection for a newly discovered and extremely rare species, before the remainder of the largest botanical collection in the western United States was consumed by fire. The entire laboratory and all the records of Benjamin R. Jacobs, a biochemist who was researching the nutrition of everyday foods, was lost. Another treasure lost in the fires was the original California flag used in the 1846 Bear Flag Revolt at Sonoma, which at the time was being stored in a state building in San Francisco.
