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...

Ranging from Yellowstone in Wyoming to Mount Pelee in the Caribbean, from Bogoslof and Pavlov in Alaska, to Sakurajima in Japan, and, finally, to the massive volcanoes of Kilauea and Mauna Loa in Hawaii—The Last Volcano reveals the incredible journey of a man on a mission to understand the awesome power of volcanic eruptions.Volcanoes have fascinated—and terrified—people for ages. They have destroyed cities and ended civilizations. John Dvorak, the acclaimed author of Earthquake Storms, looks into the early scientific study of volcanoes and the life of the man who pioneered the field, Thomas Jaggar.Educated at Harvard, Jaggar went to the Caribbean after Mount Pelee exploded in 1902, killing more than 26,000 people. Witnessing the destruction and learning about the horrible deaths these people had suffered, Jaggar vowed to dedicate himself to a study of volcanoes. What followed was fifty years of global travel to eruptions in Italy, Alaska, Central...
