The structure and volcanic activity of the northern Tanzania sector of the Gregory Rift Valley have hitherto been less well described than those in Ethiopia and Kenya. This book focuses on northern Tanzania where, although the volcanic area is smaller than those to the north, there are major features such as Kilimanjaro, the highest mountain on the African continent; Ngorongoro, one of the largest calderas on Earth; and Oldoinyo Lengai, the world's only active carbonatite volcano. Following an account of the discovery and early exploration of the rift valley, there are descriptions of the individual volcanoes. These are set within the context of the regional geology and geophysics of the rift valley, and in relation to the structural evolution of the rift and its associated sedimentary basins which include Olduvai, an important site in the history of human evolution The volume concludes with a discussion of the volcanism as related to the plume-related African Superswell.

Most volcanoes just look like mountains, until bam! They erupt with either smoke and ash or lava. Engaging and accessible text describes and illustrates some of the most common ways that volcanoes form and erupt. Readers will be able to see how Earth's crust moves as plates, revealing the fierce activity of the layer below. Diagrams and cross sections of volcanic activity make the subject clear and easy to grasp. In a simple follow-up activity, readers model a volcanic hot spot in Earth's crust, mimicking the formation of the Hawaiian Islands.

There are more than 1,500 active volcanoes around the world. Most of Earth’s active volcanoes are found in a region called the Ring of Fire. Discover more about this feature of the natural world in Volcanoes, a title in the Focus on Earth Science series.

Why do volcanoes erupt, and in so many different ways? What happens when a volcano erupts in the sea? How can eruptions be predicted? These are a few of the questions addressed in this wide-ranging introduction to volcanoes. Assuming little background knowledge, and providing a comprehensive glossary explaining technical terms, this title deals with all aspects of volcanic features and processes. It examines them as distinctive, and often dramatic, features of the landscape, as well as potential sources of danger to human beings.; Volcanoes provide an exciting way in which to analyze some of the major geological processes. The author sets them in their world context and explains their formation, especially in relation to the many styles of eruption, and the multitude of volcanic landscape forms that result. Some major eruptions are selected to illustrate this eruptive variety and the impact on surrounding populations. Distinctive landscape forms, from flows to cones and calderas, are described with reference to the "biographies" of the volcanoes. There are chapters devoted to stratovolcanoes, hydrovolcanic features and erosional processes. A final chapter examines the latest methods of predicting volcanic eruptions and moderating their effects.; Drawing on an unusually wide range of sources in the French, Spanish and Portuguese literature, as well as English, the author presents examples and illustrations from around the world, including the Aegean, the French West Indies, the American West, the Azores and the Canary Islands, Italy and central France. He has also translated various eye-witness accounts of volcanic events and has included a revised version of Pliny's account of the eruption of Vesuvius.

VOLCANOES Since the publication of the first edition of Volcanoes in 2010, our world of volcanology has changed in exciting ways. Volcanoes have continued to erupt (some 61 eruptions with VEI magnitudes greater than 3 have taken place since 2010), and in this revised and updated edition, the authors describe the largest of these, and the ones that have had the most impact on society. Volcanoes, Second Edition, contains more than 80 new photographs and figures to better illustrate volcanic features and processes, with an updated Bibliography that includes important papers describing recent eruptions and new findings. Volcanologic research is improving the foundations of knowledge upon which all our science rests, and we briefly summarize the most important of these advances and new research tools developed over the past eleven years. The most productive of these new tools are remotely operated, constantly monitoring volcanoes and their impacts on the Earth’s atmosphere from space and exploring new volcanic worlds beyond the bounds of Earth. Remotely Operated Vehicles (ROVs) are now widely available to understand better the most active volcanoes on Earth - those beneath the sea. This superlative textbook will enable students who may never see an erupting volcano to evaluate news stories about far-away eruptions, and to distinguish between overly sensational stories and factual reporting that puts facts in context. Emergency managers, land use planners, and civic officials also need to understand volcanic processes when their communities are threatened – this book will inform and guide them in their decision-making. Avoiding overly technical discussions and unnecessary use of jargon, with the important needs of civil authorities, teachers and students particularly in mind, this second edition of Volcanoes will also be of interest to general readers who are interested in these fascinating and ever-changing features of our dynamic planet.

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
