On April 18, 1906, at 05:12 AM PST, a powerful earthquake with a magnitude of 7.9 struck the San Francisco area in California. The disaster led to devastating fires that lasted for several days, resulting in over 3,000 deaths and the destruction of more than 80% of the city. This earthquake is the deadliest in U.S. history and has the highest death toll from a natural disaster in California. While the earthquake and its aftershocks were damaging, the subsequent fires caused by ruptured gas mains were far more catastrophic, destroying approximately 25,000 buildings and costing an estimated $350 million at the time, equivalent to $8.9 billion today.

Conclusion: If you were trying to build an earthquake proof house in real life, what sort of materials and features would you choose? Why would you choose them?

Extend your thinking: Some parts of San Francisco used to be marshes, or wetlands. These areas were filled in with soil to form dry land. This type of ground is called landfill. Houses and even tall buildings are built on landfill in San Francisco.

Would you rather build on bedrock or landfill? Explain your answer.
