Ours is an age of disasters: natural, as in hurricanes, tsunamis, famines, earthquakes, fires, and man-made, as in war and terrorism.
It's hardly surprising, then, that such a distinguished writer as Simon Winchester, author of The Professor and the Madman and Krakatoa, should commemorate the approaching 100th anniversary of the earthquake and fire that began at dawn on April 18, 1906, and nearly destroyed San Francisco.
But Winchester doesn't confine himself to the disaster itself. He provides a virtual guidebook to the world of tremors and earthquakes and the geological conditions that produce them. He also examines the long-range effects of the San Francisco disaster.
With hurricanes Katrina and Rita fresh in our memory, Winchester's words on the far-reaching consequences of natural calamities strike home:
Seldom does an entire and very large urban community fall victim to utter disaster ... The dropping of the atomic bombs on Hiroshima and Nagasaki are among the most obvious. The Great Fire of London in 1666. ... The huge earthquake in 1755 in Lisbon — and then, in 1906, San Francisco. ... The largest of these cities and areas survived [because they] exist for reasons that go far beyond the accumulation of buildings that is their outward manifestation. Their presence ... is invariably due to some combination of geography and of climate, together with some vague and indefinable organic reason that persuades mankind to settle there.
So it was with New Orleans and San Francisco. Otherwise, who would live in a city situated below sea level and adjoining a stormy sea? Who would want to settle in a place where, over the years, numerous earthquakes and fires have occurred?
In New Orleans, the catastrophe came from the sea; in San Francisco, from the earth, specifically the San Andreas Fault, which runs from Northern to Southern California, ending at the Salton Sea near the Mexican border.
Winchester, who trained in geology at Oxford, gives the reader a short course in geological theory, detailing the history of geological ideas. He shows why the 1906 earthquake occurred and why such a catastrophe will almost certainly recur near the same place.
The San Francisco earthquake changed the life of the city. More than 28,000 buildings were laid waste. Estimates of the dead range from about 600 to about 3,000. More than half of the city's population of 400,000 were left homeless.
Before the quake, moreover, San Francisco was the preeminent city of the American West. After the quake, slowly but inexorably, that title passed to Los Angeles, 400 miles to the south. Various things wrought the change, but among them was this: The San Andreas Fault in Southern California has never been as destructive as in the north. Los Angeles has had its quakes, but so far none has come close to devastating the city.
