Earthquake Storms

A geologist explores the fault line that threatens disaster for millions in this “must-read for earthquake buffs—and West Coast residents” (Library Journal).
 

It is a prominent geological feature that is almost impossible to see unless you know where to look. Hundreds of thousands of people drive across it every day. The San Andreas Fault is everywhere, and primed for a colossal quake. For decades, scientists have warned that such a sudden shifting of the Earth’s crust is inevitable. In fact, it is a geologic necessity.The San Andreas fault runs almost the entire length of California, from the redwood forest to the east edge of the Salton Sea. Along the way, it passes through two of the largest urban areas of the country—San Francisco and Los Angeles. Dozens of major highways and interstates cross it. Scores of housing developments have been planted over it. The words “San Andreas” are so familiar today that they have become synonymous with earthquake.Yet, few people understand the San Andreas or the network of subsidiary faults it has spawned. Some run through Hollywood, others through Beverly Hills and Santa Monica. The Hayward fault slices the football stadium at the University of California in half. Even among scientists, few appreciate that the San Andreas fault is a transient, evolving system that, as seen today, is younger than the Grand Canyon and key to our understanding of earthquakes worldwide.

Originally trained as a lunar scientist, John Dvorak, PhD, spent twenty years operating a large telescope at Mauna Kea for the Institute for Astronomy, University of Hawaii. His writing has appeared as cover stories for Scientific American, Astronomy and Physics Today. His books include Earthquake Storms and The Last Volcano, both available from Pegasus Books.
