It’s been a hundred years since the
last big one in California, the 1906 San Francisco earthquake, which helped give
birth to modem earthquake science. A century later, we have a highly successful
theory, called plate tectonics, that explains why 1906-type earthquakes happen--
along with why continents drift, mountains rise, and volcanoes line the Pacific
Rim. Plate tectonics may be one of the signature triumphs of the human mind,
geology’s answer to biology’s theory of evolution. There’s the broader question: Are there clear patterns, rules, and regularities in earthquakes, or are they inherently random and chaotic Maybe, as Berkeley seismologist Robert Nadeau says, "A lot of the randomness is just lack of knowledge."
