Volcanic eruptions are common, with more than 50 volcanic eruptions in the United States alone in the past 31 years. These eruptions can have devastating economic and social consequences, even at great distances from the volcano. Fortunately many eruptions are preceded by unrest that can be detected using ground, airborne, and spaceborne instruments. Data from these instruments, combined with basic understanding of how volcanoes work, form the basis for forecasting eruptionsâ€"where, when, how big, how long, and the consequences. Accurate forecasts of the likelihood and magnitude of an eruption in a specified timeframe are rooted in a scientific understanding of the processes that govern the storage, ascent, and eruption of magma. Yet our understanding of volcanic systems is incomplete and biased by the limited number of volcanoes and eruption styles observed with advanced instrumentation. Volcanic Eruptions and Their Repose, Unrest, Precursors, and Timing identifies key science questions, research and observation priorities, and approaches for building a volcano science community capable of tackling them. This report presents goals for making major advances in volcano science.

On an August evening around AD 600, residents of the Cerén village in the Zapotitán Valley of what is now El Salvador were sitting down to their nightly meal when ground tremors and loud steam emissions warned of an impending volcanic eruption. The villagers fled, leaving their town to be buried under five meters of volcanic ash and forgotten until a bulldozer uncovered evidence of the extraordinarily preserved town in 1976. The most intact Precolumbian village in Latin America, Cerén has been called the "Pompeii of the New World." This book presents complete and detailed reports of the excavations carried out at Cerén since 1978 by a multidisciplinary team of archaeologists, ethnographers, volcanologists, geophysicists, botanists, conservators, and others. The book is divided into sections that discuss the physical environment and resources, household structures and economy, special buildings and their uses, artifact analysis, and topical and theoretical issues. As the authors present and analyze Cerén's houses and their goods, workshops, civic and religious buildings, kitchen gardens, planted fields, and garbage dumps, a new and much clearer picture of how commoners lived during the Maya Classic Period emerges. These findings constitute landmark contributions to the anthropology and archaeology of Central America.

When the volcano Tambora erupted in Indonesia in 1815, as many as 100,000 people perished as a result of the blast and an ensuing famine caused by the destruction of rice fields on Sumbawa and neighboring islands. Gases and dust particles ejected into the atmosphere changed weather patterns around the world, resulting in the infamous ''year without a summer'' in North America, food riots in Europe, and a widespread cholera epidemic. And the gloomy weather inspired Mary Shelley to write the gothic novel Frankenstein. This book tells the story of nine such epic volcanic events, explaining the related geology for the general reader and exploring the myriad ways in which the earth's volcanism has affected human history. Zeilinga de Boer and Sanders describe in depth how volcanic activity has had long-lasting effects on societies, cultures, and the environment. After introducing the origins and mechanisms of volcanism, the authors draw on ancient as well as modern accounts--from folklore to poetry and from philosophy to literature. Beginning with the Bronze Age eruption that caused the demise of Minoan Crete, the book tells the human and geological stories of eruptions of such volcanoes as Vesuvius, Krakatau, Mount Pelée, and Tristan da Cunha. Along the way, it shows how volcanism shaped religion in Hawaii, permeated Icelandic mythology and literature, caused widespread population migrations, and spurred scientific discovery. From the prodigious eruption of Thera more than 3,600 years ago to the relative burp of Mount St. Helens in 1980, the results of volcanism attest to the enduring connections between geology and human destiny.

Volcanoes are unquestionably one of the most spectacular and awe-inspiring features of the physical world. Our paradoxical fascination with them stems from their majestic beauty and powerful, sometimes deadly, destructiveness. Notwithstanding the tremendous advances in volcanology since ancient times, some of the mystery surrounding volcanic eruptions remains today. The Encyclopedia of Volcanoes summarizes our present knowledge of volcanoes; it provides a comprehensive source of information on the causes of volcanic eruptions and both the destructive and beneficial effects. The early chapters focus on the science of volcanism (melting of source rocks, ascent of magma, eruption processes, extraterrestrial volcanism, etc.). Later chapters discuss human interface with volcanoes, including the history of volcanology, geothermal energy resources, interaction with the oceans and atmosphere, health aspects of volcanism, mitigation of volcanic disasters, post-eruption ecology, and the impact of eruptions on organismal biodiversity. - Provides the only comprehensive reference work to cover all aspects of volcanology - Written by nearly 100 world experts in volcanology - Explores an integrated transition from the physical process of eruptions through hazards and risk, to the social face of volcanism, with an emphasis on how volcanoes have influenced and shaped society - Presents hundreds of color photographs, maps, charts and illustrations making this an aesthetically appealing reference - Glossary of 3,000 key terms with definitions of all key vocabulary items in the field is included

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.

Teaching children how to manage their thoughts and words without interrupting. Louis always interrupts! All of his thoughts are very important to him, and when he has something to say, his words rumble and grumble in his tummy, they wiggle and jiggle on his tongue and then they push on his teeth, right before he ERUPTS (or interrupts). His mouth is a volcano! But when others begin to interrupt Louis, he learns how to respectfully wait for his turn to talk. My Mouth Is A Volcano takes an empathetic approach to the habit of interrupting and teaches children a witty technique to help them manage their rambunctious thoughts and words. Told from Louis' perspective, this story provides parents, teachers, and counselors with an entertaining way to teach children the value of respecting others by listening and waiting for their turn to speak.
