Simon Winchester, New York Times bestselling author of The Professor and the Madman, examines the legendary annihilation in 1883 of the volcano-island of Krakatoa, which was followed by an immense tsunami that killed nearly forty thousand people. The effects of the immense waves were felt as far away as France. Barometers in Bogota and Washington, D.C., went haywire. Bodies were washed up in Zanzibar. The sound of the island's destruction was heard in Australia and India and on islands thousands of miles away. Most significant of all -- in view of today's new political climate -- the eruption helped to trigger in Java a wave of murderous anti-Western militancy among fundamentalist Muslims, one of the first outbreaks of Islamic-inspired killings anywhere. Krakatoa gives us an entirely new perspective on this fascinating and iconic event.
On August 27, 1883, the volcano-island of Krakatoa erupted with such force that it was completely destroyed. The explosion could be heard from thousands of miles away, and triggered an immense tsunami that killed nearly 40,000 people. And that was just the beginning.In this New York Times bestseller, Simon Winchester, author of The Professor and the Madman, explores the worldwide impact of the Krakatoa catastrophe. The effects of the tsunami were felt as far away as France. Barometers in Washington, D.C. went haywire. And dust from the volcano drifted into Earth's atmosphere, where it caused temperatures around the globe to plummet. Krakatoa gives us an entirely new historical and geological perspective on an unforgettable natural disaster. Simon Winchester's many books include The Professor and the Madman, The Map That Changed the World, Krakatoa, and A Crack in the Edge of the World. Each has been a New York Times bestseller and has appeared on numerous "best" and "notable" lists. Mr. Winchester was made an Officer of the Order of the British Empire (OBE) in 2006. He lives in Western Massachusetts. "Brilliant ... One of the best books ever written about the history and significance of a natural disaster." -- New York Times Book Review--Chicago Sun-Times
The first of John McPhee's works in his series on geology and geologists, Basin and Range is a book of journeys through ancient terrains, always in juxtaposition with travels in the modern world--a history of vanished landscapes, enhanced by the histories of people who bring them to light. The title refers to the physiographic province of the United States that reaches from eastern Utah to eastern California, a silent world of austere beauty, of hundreds of discrete high mountain ranges that are green with junipers and often white with snow. The terrain becomes the setting for a lyrical evocation of the science of geology, with important digressions into the plate-tectonics revolution and the history of the geologic time scale.

The 2011 devastating, tsunami-triggering quake off the coast of Japan and 2010's horrifying destruction in Haiti reinforce the fact that large cities in every continent are at risk from earthquakes. Quakes threaten Los Angeles, Beijing, Cairo, Delhi, Singapore, and many more cities, and despite advances in earthquake science and engineering and improved disaster preparedness by governments and international aid agencies, they continue to cause immense loss of life and property damage. Earthquake explores the occurrence of major earthquakes around the world, their effects on the societies where they strike, and the other catastrophes they cause, from landslides and fires to floods and tsunamis. Examining the science involved in measuring and explaining earthquakes, Andrew Robinson looks at our attempts to design against their consequences and the possibility of having the ability to predict them one day. Robinson also delves into the ways nations have mythologized earthquakes through religion and the arts--Norse mythology explained earthquakes as the violent struggling of the god Loki as he was punished for murdering another god, the ancient Greeks believed Poseidon caused earthquakes whenever he was in a bad mood or wanted to punish people, and Japanese mythology states that Namazu, a giant catfish, triggers quakes when he thrashes around. He discusses the portrayal of earthquakes in popular culture, where authors and filmmakers often use the memory of cities laid to waste--such as Kobe, Japan, in 1995 or San Francisco in 1906--or imagine the hypothetical "Big One," the earthquake expected someday out of California's San Andreas Fault. With tremors happening in seemingly implausible places like Chicago and Washington DC, Earthquake is a timely book that will enrich earthquake scholarship and enlighten anyone interested in these ruinous natural disasters.
At various times in a span of fifteen years, John McPhee made geological field surveys in the company of Eldridge Moores, a tectonicist at the University of California at Davis. The result of these trips is Assembling California, a cross-section in human and geologic time, from Donner Pass in the Sierra Nevada through the golden foothills of the Mother Lode and across the Great Central Valley to the wine country of the Coast Ranges, the rock of San Francisco, and the San Andreas family of faults. The two disparate time scales occasionally intersect--in the gold disruptions of the nineteenth century no less than in the earthquakes of the twentieth--and always with relevance to a newly understood geologic history in which half a dozen large and separate pieces of country are seen to have drifted in from far and near to coalesce as California. McPhee and Moores also journeyed to remote mountains of Arizona and to Cyprus and northern Greece, where rock of the deep-ocean floor has been transported into continental settings, as it has in California. Global in scope and a delight to read, Assembling California is a sweeping narrative of maps in motion, of evolving and dissolving lands.
For months in early 1980, scientists, journalists, and nearby residents listened anxiously to rumblings from Mount St. Helens in southwestern Washington State. Still, no one was prepared when a cataclysmic eruption blew the top off of the mountain, laying waste to hundreds of square miles of land and killing fifty-seven people. Steve Olson interweaves vivid personal stories with the history, science, and economic forces that influenced the fates and futures of those around the volcano. Eruption delivers a spellbinding narrative of an event that changed the course of volcanic science, and an epic tale of our fraught relationship with the natural world.
Despite growing evidence of geothermic activity under America's first and foremost national park, it took geologists a long time to realize that there was actually a volcano beneath Yellowstone. And then, why couldn't they find the caldera or crater? Because, as an aerial photograph finally revealed, the caldera is 45 miles wide, encompassing all of Yellowstone. What will happen, in human terms, when it erupts?
Greg Breining explores the shocking answer to this question and others in a scientific yet accessible look at the enormous natural disaster brewing beneath the surface of the United States. Yellowstone is one of the world's five "super volcanoes." When it erupts, much of the nation will be hit hard.
Though historically Yellowstone has erupted about every 600,000 years, it has not done so for 630,000, meaning it is 30,000 years overdue. Starting with a scenario of what will happen when Yellowstone blows, this fascinating study describes how volcanoes function and includes a timeline of famous volcanic eruptions throughout history.
