Eclipses have stunned, frightened, emboldened, and mesmerized people for thousands of years. They were recorded on ancient turtle shells discovered in the Wastes of Yin in China, on clay tablets from Mesopotamia and on the Mayan "Dresden Codex". They are mentioned in Homer's Iliad and Odyssey and at least eight times in the Bible. Columbus used them to trick people, while Renaissance painter Taddeo Gaddi was blinded by one. Sorcery was banished within the Catholic Church after astrologers used an eclipse to predict a pope's death. In Mask of the Sun, acclaimed writer John Dvorak explains the importance of the number 177 and why the ancient Romans thought it was bad to have sexual intercourse during an eclipse (whereas other cultures thought it would be good luck). Even today, pregnant women in Mexico wear safety pins on their underwear during an eclipse. Eclipses are an amazing phenomena - unique to Earth - that have provided the key to much of what we now know and understand about the sun, our moon, gravity, and the workings of the universe. Both entertaining and authoritative, Mask of the Sun reveals the humanism behind the science of both lunar and solar eclipses. With insightful detail and vividly accessible prose, Dvorak provides explanations as to how and why eclipses occur.

Volcanoes have fascinated - and terrified - people for ages. They have destroyed cities and ended civilizations. In this book, John Dvorak, the acclaimed author of Earthquake Storms, looks into the early years of volcanology and its "father", Thomas Jaggar. Jaggar was the youngest of five scientists to investigate the explosion of Mount Pelee in Martinique, which leveled the entire city of St. Pierre and killed its entire population in two minutes. This explosion changed science forever, and Jaggar became obsessed with understanding the force of nature that could do this. Falling in love with a widowed schoolteacher who shared his passion, Jaggar devoted his life to studying volcanic activity and the mysteries beneath the earth's surface. From their precarious perch, this dynamic husband and wife duo would discover a way to predict volcanic eruptions and tsunamis, promote geothermal energy, and theorize new ways to study the ocean bottom.

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.
