1906 San Francisco earthquake

The 1906 San Francisco earthquake was a powerful earthquake that happened along the coast of Northern California very early in the morning on April 18, 1906. The earthquake was very strong, and it caused shaking that could be felt from Eureka in the north all the way to the Salinas Valley south of the San Francisco Bay Area.

After the shaking stopped, fires started in San Francisco and burned for several days. These fires destroyed much of the city. Sadly, many people lost their lives because of the earthquake and the fires. This event is remembered as one of the worst earthquakes in the history of the United States. It was also a big natural disaster for California at that time.

Tectonic setting

The San Andreas Fault is a large crack in the Earth's surface. It is part of the edge between two huge pieces of Earth's crust, called plates. One plate, the Pacific plate, moves north. The other plate, the North American plate, stays mostly still. This movement makes the ground shift sideways. The fault runs through California, from the Salton Sea in the south to Cape Mendocino in the north, for about 810 miles (1,300 km). Scientists have measured how much the ground moved during earthquakes here, with some areas shifting up to 28 feet (8.5 m).

Earthquake

The 1906 earthquake happened before scientists could measure earthquake strength like today. Scientists now think it was about 7.9 on a modern scale. The earthquake caused changes to the Earth's surface. The shaking was felt from Oregon to Los Angeles, and even far inland in Nevada.

A smaller shake happened about 20 to 25 seconds before the big one. The big shake lasted around 42 seconds. For many years, people thought the earthquake started near Olema, but newer studies suggest it might have started offshore from San Francisco.

The shaking was very strong in San Francisco and nearby areas, causing a lot of damage. After the main earthquake, there were many smaller quakes called aftershocks.

Damage

The earthquake shook much of Northern California and caused damage in many places. In San Francisco, many houses were ruined, and fires burned for days. Thousands of people lost their homes and set up temporary camps in parks and open spaces.

The earthquake also caused damage in other cities, such as San Jose and Santa Rosa, where much of the downtown area was destroyed.

Fires

The fires that started after the earthquake caused even more damage than the earthquake itself. Many fires began when gas lines broke. These fires destroyed many buildings in San Francisco.

One famous fire started when a woman lit her stove for breakfast. This fire destroyed a large area, including important buildings. The city's fire chief could not help because he was hurt in the earthquake. The fires burned for four days and nights.

Many valuable things were lost in the fires. A scientist named Alice Eastwood saved many plant specimens before her lab burned down.

Response

When the earthquake struck, many people worked together to help the city. Soldiers came to keep things safe, protect important places, and help put out fires. They also helped feed and find places for people who had to leave their homes. Over time, more people joined in to clear rubble and help with rescues.

Unfortunately, there were some problems with people taking things that weren’t theirs, and leaders had to make tough decisions to keep order. Most of the soldiers did their best to help the community during this difficult time.

Aftermath

The earthquake caused a lot of damage, and many buildings were lost. Leaders in San Francisco wanted to rebuild the city quickly. Plans were made to rebuild, but it took time because many banks were damaged.

After the earthquake, a baseball game was played in New York City to raise money for those affected. A psychologist named William James visited San Francisco and was impressed by how people worked together to help each other.

Reconstruction

The earthquake helped change San Francisco. The University of California, San Francisco started treating people in temporary tents, which led to building new medical facilities. New plans were made to change the city's streets and buildings. The city rebuilt quickly, and by 1915, it was ready to celebrate its recovery.

Housing

The Army built many small houses out of wood to help people who lost their homes. These houses were painted blue and rented for a small amount of money. Some of these houses are still left today.

Relief

People all over the world sent money and supplies to help San Francisco. Governments and companies gave large amounts of money, and the U.S. Congress sent supplies and tents. Even though help came from many places, it was hard for families to rebuild.

Insurance payments

Insurance companies had to pay money for fire damage, but many went bankrupt. This caused problems and led to changes in how insurance for fires was handled.

Centennial commemorations

In 2006, many events celebrated the earthquake that happened 100 years earlier. These events included award presentations, religious services, TV movies, and special lectures. The tourism industry also marked this important anniversary.

Some people who lived through the earthquake in 1906 were still alive to attend these events in 2006. Over the years, more survivors were found and attended reunions. In 2005, a film about the earthquake was added to a special list of important American films to keep safe.

Willard Worden gallery

Willard Worden was a photographer in San Francisco. He took many pictures during the big earthquake and fires in 1906. He used old cameras to show the fire, damaged buildings, and ruins at Stanford University. His photographs helped people understand what happened and are kept in important museums.

One famous photo shows the empty porch of a big house on Nob Hill, with the ruined City Hall behind it. This picture became a symbol of the earthquake. The porch was later moved to Golden Gate Park and is called the Portals of the Past, reminding people of the city's strength.

Panoramas

San Francisco burned after a big earthquake in 1906. These pictures show the city from different places, like hotels and hills. You can see smoke, fire, and damaged buildings. Some famous spots shown are Union Square, Market Street, and the Ferry Building, along with places such as Twin Peaks and Nob Hill. The photos were taken just after the earthquake and fires.

In popular culture

The 1906 San Francisco earthquake has been featured in many books, movies, and plays. People have used this event to tell stories about courage and rebuilding.

For example, there is a disaster movie from 1936 called San Francisco starring Clark Gable, and a play named Angels in America by Tony Kushner that mentions the earthquake.

The earthquake also appears in children’s books, like Earthquake in the Early Morning from the Magic Tree House series, and in the novel Dragonwings by Laurence Yep. In the animated film Big Hero 6, the city of San Francisco is reimagined as San Fransokyo after the earthquake.
