Understanding the 1906 Earthquake Map

The 1906 San Francisco earthquake struck early on April 18, 1906, with a magnitude estimated near 7.9 on the San Andreas Fault. A useful mind map splits the event into its main branches: the geology behind the rupture, the shaking and damage across the city, the fires that followed, and the long recovery that reshaped the city.

  • Causes: the San Andreas Fault rupture and built-up tectonic strain
  • Shaking and damage: ground motion, collapsed buildings and broken utilities
  • Fires: ruptured gas mains and water shortages that spread the blaze
  • Aftermath: relief efforts, rebuilding and changes to city building codes

Use the map to revise the sequence of events and the links between causes and effects. Generate a personalized version with CogniGuide from your own notes.

Earthquake Map Questions

Common questions about the 1906 quake and how to map it.

Why did so many fires start after the 1906 earthquake?

Broken gas mains and damaged chimneys sparked fires, while the ruptured water mains left firefighters with little water to fight them. Fires burned for several days and destroyed much of the city.

What fault caused the 1906 San Francisco earthquake?

The earthquake was caused by a rupture along the San Andreas Fault, the boundary between the Pacific and North American tectonic plates.

Which files can I use to build my own map?

You can upload a PDF, Word file, PowerPoint, text or Markdown file, or an image of your notes. You can also type the topic directly.

Can the map become a quiz?

Yes. You can turn any CogniGuide map into a quiz to test yourself, and the free plan allows five creations a week.
