Which earthquake was most destructive earthquake in San Franciscos history?”
2. San Francisco: April 18, 1906 The Great San Francisco Earthquake — a 7.8 magnitude tremor — brought down structures across the Bay Area. In San Francisco, buildings crumbled, water mains broke, and streetcar tracks twisted into metal waves. But the majority of the 3,000 deaths and $524 million in property damage came from the massive post-tremor fire, which spread rapidly across the city in the absence of water to quell the flames. People as far away as southern Oregon and western Nevada felt the shaking, which lasted nearly a minute.
The San Francisco earthquake of 1906 was a major earthquake that struck San Francisco, CA and the coast of Northern California at 5:12 A.M. on Wednesday, April 18, 1906.[2] The most widely accepted estimate for the magnitude of the earthquake is a moment magnitude (Mw) of 7.8; however, other values have been proposed, from 7.7 to as high as 8.25.[3] The main shock epicenter occurred offshore about 2 miles (3 km) from the city, near Mussel Rock. It ruptured along the San Andreas Fault both northward and southward for a total of 296 miles (477 km).[4] Shaking was felt from Oregon to Los Angeles, and inland as far as central Nevada. The earthquake and resulting fire is remembered as one of the worst natural disasters in the history of the United States. The death toll from the earthquake and resulting fire, estimated to be above 3,000,[5] is the greatest loss of life from a natural disaster in California’s history. The economic impact has been compared with the more recent Hurricane Katri
