It was estimated that some 3, people died as a result of the Great San Francisco Earthquake and the devastating fires it inflicted upon the city. But if you see something that doesn't look right, click here to contact us!
On April 18, , 16 Nepali mountaineering guides, most of them ethnic Sherpas, are killed by an avalanche on Mt. It was the single deadliest accident in the history of the Himalayan peak, which rises more than 29, feet above sea level and lies across the border The U. The terrorist attack was carried out in protest of the U. In , a bloody civil war He had been called to Worms, Germany, to appear before the Diet assembly of the Holy Roman Empire and answer charges of heresy.
Rupturing the northernmost km of the San Andreas fault from northwest San Juan Bautista to the triple junction of Cape Mendocino, the earthquake confounded contemporary geologists with its large, horizontal displacements and great rupture length. Indeed the significance of the fault and recognition of its large cumulative offset would not be fully appreciated until the advent of plate tectonics more than half a century later.
Analysis of the displacements and strain in the surrounding crust led Reid to formulate his elastic-rebound theory of the earthquake source, which remains today the principal model of the earthquake cycle. As a basic reference about the earthquake and the damage it caused, geologic observations of the fault rupture and shaking effects, and other consequences of the earthquake, Lawson's report remains the authoritative work, as well as arguably the most important study of a single earthquake.
In the public's mind, this earthquake is perhaps remembered most for the fire it spawned in San Francisco, giving it the somewhat misleading appellation of the "San Francisco earthquake. The frequently quoted value of deaths caused by the earthquake and fire is now believed to underestimate the total loss of life by a factor of 3 or 4. Most of the fatalities occurred in San Francisco, and were reported elsewhere.
Fires immediately broke out in San Francisco due to broken gas lines, fallen power lines, and lanterns that had toppled over during the earthquake. Water lines were ruptured as well, which made it difficult to put the fires out. It is estimated that 3, people were killed during the earthquake and its aftershocks, which lasted for days. The earthquake displaced even more people from their homes.
The earthquake occurred as a result of a shift along the San Andreas Fault , which bisects the San Francisco Peninsula just to the west of the city. The land on the eastern side of the fault, including the city and San Francisco Bay , moved southward, while the land on the western side was pushed northward.
More than 6 meters 20 feet of displacement occurred during the quake. West Coast. Pacific coast of the United States, usually excluding Alaska. More Dates in History January.

Areas situated in sediment-filled valleys sustained stronger shaking than nearby bedrock sites, and the strongest shaking occurred in areas where ground reclaimed from San Francisco Bay failed in the earthquake.
Modern seismic-zonation practice accounts for the differences in seismic hazard posed by varying geologic conditions. As a basic reference about the earthquake and the damage it caused, geologic observations of the fault rupture and shaking effects, and other consequences of the earthquake, the Lawson report remains the authoritative work, as well as arguably the most important study of a single earthquake.
In the public's mind, this earthquake is perhaps remembered most for the fire it spawned in San Francisco, giving it the somewhat misleading appellation of the "San Francisco earthquake".
Shaking damage, however, was equally severe in many other places along the fault rupture.
