The lives of millions will be changed after it breaks, and yet so few people understand it, or even realize it runs through their backyard. Dvorak reveals the San Andreas Fault's fascinating history - and its volatile future.
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 geologicn ecessity.
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.

I am an avid eclectic reader.
This book is almost entirely focused on California, with a bit of discussion about other great quakes in world history. It is lucidly written and easily understandable to the lay person. The book covers both the geology of the San Andreas Fault and the history including such people as Grover Gilbert, Harry Fielding Reid who studied the 1906 San Francisco quake. Andrew Larson a geology professor at the University of California Berkeley who named the San Andreas Fault in 1895. Of course, Charles Richter who developed the eponymous magnitude scale was discussed in detail. Dvorak describes the history of all the known California quakes but goes into great detail about the San Francisco earthquake of 1906. He explains the 1960 discovery of plate tectonics and how that brought better understanding to the geology of California and the understanding of earthquakes. He almost makes a guide to where to go and what to look at along with what is the meaning of what you are looking at along various site of the San Andreas Fault. He gives a description how the San Andreas Fault works and how other fault secondary fault lines develop. He states that the San Andreas Fault and its many subsidiary faults are tearing California apart. He says geological California has been in a quiet time for quakes but according to past history this is going to change. Dvorak apparently worked for the U.S. Geological Survey. Overall I found this to be a most fascinating book. Malcolm Hillgartner did a great job narrating the book.
