The San Francisco Earthquake of 1906 struck California on April 18, 1906, early in the morning while many people were still asleep. At about 5:12 a.m., the earthquake shook San Francisco and nearby areas with tremendous force. The powerful movement damaged buildings, streets, water pipes, roads, and homes, becoming a defining disaster in the history of the city and an important event in the study of earthquakes in the United States.
The earthquake was caused by movement along the San Andreas Fault, a major fault line that runs through California. When the ground shifted, the force released enormous energy and caused violent shaking. Buildings made of brick and weaker materials were especially vulnerable, and many collapsed or suffered serious damage.
Although the earthquake itself was destructive, the fires that followed caused even greater damage. Broken gas lines, damaged chimneys, and collapsed buildings helped fires spread across the city. At the same time, broken water mains made it very difficult for firefighters to control the flames. For several days, fire destroyed large parts of San Francisco.
The human impact was enormous. Many people were killed or injured, and hundreds of thousands were left homeless. The shaking and fires destroyed around 28,000 buildings across San Francisco, including homes, businesses, churches, hotels, and public buildings. Families lost belongings, neighborhoods, workplaces, and places of worship in only a short time.
Survivors slept in parks, tents, camps, and temporary shelters while the city struggled to provide food, water, medical help, and safety. Emergency workers, firefighters, soldiers, volunteers, and ordinary citizens all played roles in responding to the disaster. Some areas were cleared to stop the fires from spreading, and relief efforts helped people survive in the days and weeks after the earthquake.
Rebuilding San Francisco became a major task. Streets, homes, businesses, public buildings, and transportation systems had to be repaired or replaced. The earthquake also taught important lessons about stronger buildings, fire prevention, emergency planning, and the need to understand seismic risks in California.
