Locals refer to it as The Fire - did much more damage than the quake did...
I’ve heard some people call it the “Ham and Eggs Fire.”
Apparently someone tried to cook breakfast after the quake, but there was a large crack in the chimney.
Some have claimed that this was the source of the Great Fire.
The earthquake ruptured SF’s gas and water mains which started fires that then became impossible to fight.
Writers described walking through neighborhoods where all seemed normal except that they were ultimately doomed to the advancing fires. Dynamite “was lavishly used” to attempt to create corridors across which the fires could not pass, but they did, and the city burned following “a mere thirty seconds’ twitching of the Earth’s crust”.
Preachers called the SF fire a manifestation of God’s wrath against man’s sinful pride. They would say the same a few years later with the sinking of the Titanic.
