On November 13, 1985, catastrophic mudflows swept down the slopes of the erupting Nevado del Ruiz volcano, destroying structures in their paths. Various estimates of deaths ranged as high as 24,000 residents. Though the nature and extent of risk posed by the mudflows to local communities were well documented before the event and extensive efforts had been made to communicate this information to those at risk, the affected communities were caught largely unaware. This volume analyzes the disaster's many aspects: the extent, constitution, and behavior of the mudflows; the nature of damage to structures; the status of the area's disaster warning system; and the extent of the area's disaster preparedness, emergency response actions, and disaster relief effortsâ€"both at the time of the disaster and in the first few months following the event.

On January 14, 1993, a team of scientists descended into the crater of Galeras, a restless Andean volcano in southern Colombia, for a day of field research. As the group slowly moved across the rocky moonscape of the caldera near the heart of the volcano, Galeras erupted, its crater exploding in a barrage of burning rocks and glowing shrapnel. Nine men died instantly, their bodies torn apart by the blast. While others watched helplessly from the rim, Colombian geologist Marta Calvache raced into the rumbling crater, praying to find survivors. This was Calvache's second volcanic disaster in less than a decade. In 1985 Calvache was part of a group of Colombia's brightest young scientists that had been studying activity at Nevado del Ruiz, a volcano three hundred miles north of Galeras. They had warned of the dire consequences of an eruption for months, but their fledgling coalition lacked the resources and muscle to implement a plan of action or sway public opinion. When Nevado del Ruiz erupted suddenly in November 1985, it wiped the city of Armero off the face of the earth and killed more than twenty-three thousand people -- one of the worst natural disasters of the twentieth century. No Apparent Danger links the characters and events of these two eruptions to tell a riveting story of scientific tragedy and human heroism. In the aftermath of Nevado del Ruiz, volcanologists from all over the world came to Galeras -- some to ensure that such horrors would never be repeated, some to conduct cutting-edge research, and some for personal gain. Seismologists, gas chemists, geologists, and geophysicists hoped to combine their separate areas of expertise to better understand and predict the behavior of monumental forces at work deep within the earth. And yet, despite such expertise, experience, and training, crucial data were ignored or overlooked, essential safety precautions were bypassed, and fifteen people descended into a death trap at Galeras. Incredibly, expedition leader Stanley Williams was one of five who survived, aided bravely by Marta Calvache and her colleagues. But nine others were not so lucky. Expertly detailing the turbulent history of Colombia and the geology of its snow-peaked volcanoes, Victoria Bruce weaves together the stories of the heroes, victims, survivors, and bystanders, evoking with great sensitivity what it means to live in the shadow of a volcano, a hair's-breadth away from unthinkable natural calamity, and shows how clashing cultures and scientific arrogance resulted in tragic and unnecessary loss of life.

By the year 2000, the number of people at risk from volcanic hazards is likely to increase to around half a billion. Since 1980, significant advances have been made in volcano monitoring, the data from which provides the sole scientific basis for eruption prediction. Here, internationally renowned and highly experienced specialists provide 25 comprehensive articles covering a wide range of related topics: monitoring techniques and data analysis; modelling of monitoring data and eruptive phenomena; volcanic hazards and risk assessment; and volcanic emergency management. Selected case histories of recent volcanic disasters, such as Mount Pinatubo in the Philippines, demonstrate that effective communication - between scientists, civil authorities, the media and the population at risk - is essential to reducing the danger.

This true, up-close account of a volcano’s eruption “artfully blends science writing and history with pure, heart-pounding action” (Mark Bowden, bestselling author of Black Hawk Down). In 1993, Stanley Williams, an eminent volcanologist, was standing on top of a Colombian volcano called Galeras when it erupted, killing six of his colleagues instantly. As Williams tried to escape the blast, he was pelted with white-hot projectiles traveling faster than bullets. Within seconds he was cut down, his skull fractured, his right leg almost severed, his backpack aflame. Williams lay helpless and near death on Galeras’s flank until two brave women—friends and fellow volcanologists—mounted an astonishing rescue effort to carry him safely off the mountain. Surviving Galeras is both a harrowing first-person account of an eruption and its aftermath, and a look at the fascinating, high-risk world of volcanology, exploring the profound impact volcanoes have had on the earth’s landscapes and civilizations. Even with improved, highly-sensitive measuring tools and protective equipment, at least one volcanologist, on average, dies each year. This book reveals how Williams and his fellow scientist-adventurers continue to unveil the enigmatic and miraculous workings of volcanoes and piece together methods to predict their actions—potentially saving many human lives. “I thoroughly enjoyed this excellent book . . . [A] riveting story.” —Dava Sobel, author of The Glass Universe “Popular science at its best.” —The New York Times “[A] page-turner.” —Booklist

Volcanoes are essential elements in the delicate global balance of elemental forces that govern both the dynamic evolution of the Earth and the nature of Life itself. Without volcanic activity, life as we know it would not exist on our planet. Although beautiful to behold, volcanoes are also potentially destructive, and understanding their nature is critical to prevent major loss of life in the future. Richly illustrated with over 300 original color photographs and diagrams the book is written in an informal manner, with minimum use of jargon, and relies heavily on first-person, eye-witness accounts of eruptive activity at both "red" (effusive) and "grey" (explosive) volcanoes to illustrate the full spectrum of volcanic processes and their products. Decades of teaching in university classrooms and fieldwork on active volcanoes throughout the world have provided the authors with unique experiences that they have distilled into a highly readable textbook of lasting value. Questions for Thought, Study, and Discussion, Suggestions for Further Reading, and a comprehensive list of source references make this work a major resource for further study of volcanology. Volcanoes maintains three core foci: Global perspectives explain volcanoes in terms of their tectonic positions on Earth and their roles in earth history Environmental perspectives describe the essential role of volcanism in the moderation of terrestrial climate and atmosphere Humanitarian perspectives discuss the major influences of volcanoes on human societies. This latter is especially important as resource scarcities and environmental issues loom over our world, and as increasing numbers of people are threatened by volcanic hazards Readership Volcanologists, advanced undergraduate, and graduate students in earth science and related degree courses, and volcano enthusiasts worldwide.

This Atlas illustrates the significant reduction in glacier mass happening throughout the Andean region. It quantifies the contribution of glaciers to drinking water supplies in cities and to agriculture, hydropower and industries. A reduction in glacier mass results in a long-term reduction in seasonal melt water - which is the mainstay of livelihoods for millions of people.

An impressive collection of 62 technical papers recounting the eruption of Mo Pinatubo in 1991 and its aftermath. The contributors reflect the internatio cooperation exhibited during the eruption (ten times larger than Mount St. Helens) and explore the precursors, processes, and products of the eru
