What was the San Francisco earthquake of 1906?
The San Francisco earthquake of 1906 struck on April 18, 1906, at 5:12 am off the northern California coast. It had a magnitude of 7.9 and caused severe damage in San Francisco, San Jose, Salinas, and Santa Rosa. The earthquake was caused by a slip of the San Andreas Fault along a 270-mile segment.
The earthquake was followed by a fire that lasted four days, which leveled more than 500 city blocks and destroyed about 28,000 buildings. Originally, the death toll was thought to be around 700, but it is now believed to have exceeded 3,000. Around 250,000 people were left homeless.

When and where did the earthquake occur?
The San Francisco earthquake occurred on April 18, 1906, at 5:12 am off the northern California coast. It had a magnitude of 7.9. The San Andreas Fault slipped along a segment about 270 miles (430 km) long, from San Juan Bautista in San Benito county to Humboldt county, possibly extending out under the sea. The shaking was felt from Los Angeles to Coos Bay, Oregon. Damage was severe in San Francisco and other towns near the fault, such as San Jose, Salinas, and Santa Rosa. The quake was followed by a massive fire that leveled more than 500 blocks in the city center. The death toll is now believed to have exceeded 3,000.

How strong was the earthquake and what caused it?
The San Francisco earthquake of 1906 was a major earthquake that occurred on April 18, 1906. It had a magnitude of 7.9. The San Andreas Fault slipped along a segment about 270 miles (430 km) long, causing the earthquake and severe damage in San Francisco and other towns nearby.
Geologic field studies of this earthquake led to the detailed formation of the theory that elastic rebound of strained faults causes the shaking associated with earthquakes.

What kind of damage did the earthquake do to San Francisco?
The San Francisco earthquake of 1906, a magnitude 7.9 quake, struck on April 18, 1906, causing severe damage in San Francisco and nearby towns. The quake was followed by a massive fire that burned for four days, leveling more than 500 city blocks and destroying some 28,000 buildings. Property losses totaled an estimated $350 million. While initial reports estimated 700 deaths, the toll is now believed to have exceeded 3,000, and about 250,000 were left homeless.

How did the people of San Francisco respond to the disaster?
The San Francisco earthquake of 1906 and subsequent fire left approximately 250,000 people homeless. Survivors sought refuge in places like Golden Gate Park and the dunes west of the city, while others fled to nearby towns.
Relief efforts quickly commenced, with shipments of food and clothing arriving in the city. Financial aid, amounting to tens of millions of dollars, poured in from various sources, including Europe, Japan, China, and other parts of the Americas.
Despite the insurance payments of around $300 million, the reconstruction was largely fueled by the courage and persistence of the local population. The city was rebuilt with earthquake- and fire-resistant measures. By 1915, San Francisco showcased its recovery efforts to the world at the Panama-Pacific International Exposition.

What were the long-term effects of the earthquake on the city and its rebuilding?
The San Francisco earthquake of 1906 and subsequent fire led to the destruction of over 500 city blocks and an estimated \$350 million in property damage. Approximately 250,000 people were left homeless, and the death toll exceeded 3,000.
In the aftermath, San Francisco rebuilt much of the city to be earthquake- and fire-resistant. By 1915, San Francisco invited the world to the Panama-Pacific International Exposition to display the results of its reconstruction efforts. Today, engineers and seismologists continue to warn that a similar earthquake could strike again.

San Francisco earthquake of 1906, major earthquake with a magnitude of 7.9 that occurred on April 18, 1906, at 5:12 am off the northern California coast. The San Andreas Fault slipped along a segment about 270 miles (430 km) long, extending from San Juan Bautista in San Benito county to Humboldt county and from there perhaps out under the sea to an unknown distance. The shaking was felt from Los Angeles in the south to Coos Bay, Oregon, in the north. Damage was severe in San Francisco and in other towns situated near the fault, including San Jose, Salinas, and Santa Rosa.
San Francisco had experienced earthquakes in 1864, 1898, and 1900 but nothing like the 1906 event. Just after 5:00 am on April 18, a noise "like the roar of 10,000 lions" rose as the entire city began to tremble and shake. Cable cars abruptly stopped, City Hall crumbled, and the Palace Hotel’s glass roof splintered and littered the courtyard below.
The quake was followed by a massive fire that swept from the business section near Montgomery Street and the South of Market district toward Russian Hill, Chinatown, North Beach, and Telegraph Hill. The blaze continued for four days, until its smouldering ashes were ultimately extinguished by rain. In the process, more than 500 blocks in the city centre—covering some 4 square miles (10 square km)—were leveled. The inferno destroyed some 28,000 buildings, and the total property value loss was estimated at $350 million.
Some 700 people originally were thought to have died in the disaster, but the death toll is now believed to have exceeded 3,000. Moreover, about 250,000 were left homeless; survivors camped in Golden Gate Park and dunes west of the city or fled to outlying towns. Within a short time, relief shipments of food and clothing reached the city, and several tens of millions of dollars in financial aid arrived from foreign sources, including Europe, Japan and China, and other parts of the Americas. Although insurance payments in the neighbourhood of $300 million were forthcoming, the long task of reconstruction was sustained by local courage and persistence.
Much of the city was rebuilt to be earthquake- and fire-resistant. New plans for civic development made headway as the debris of the old city vanished. In 1915 San Francisco invited the world to see the results of its efforts at the Panama-Pacific International Exposition.
