San Francisco, 1906: The City After the Earthquake

A city shaken awake

On 18 April 1906, a major earthquake struck San Francisco shortly after 5 a.m. The rupture along the San Andreas Fault produced intense shaking across the region. Buildings and infrastructure were damaged, but the disaster became even larger as fires spread through the city.

Fire became the second disaster

Water mains were broken and firefighting was severely constrained. Fires burned across large parts of San Francisco for several days. Dense construction, wooden buildings and damaged utilities turned the earthquake into an urban catastrophe that could not be contained quickly.

Photographs from the ruins

Photographers recorded streets lined with collapsed facades, damaged buildings and long views across the ruined city. The images were not simply records of destruction. They became a way for officials, residents and distant audiences to understand the scale of the disaster and the challenge of rebuilding.

Why it matters

The earthquake reshaped San Francisco physically and politically. Reconstruction produced new buildings and infrastructure while also influencing later thinking about seismic risk. The surviving photographs preserve something maps cannot: the visual experience of a familiar city suddenly stripped of its normal landmarks.
