This volume examines the impact of and responses to historic earthquakes and volcanic eruptions in the Azores. Study is placed in the contexts of: the history and geography of this fascinating archipelago; progress being made in predicting future events and policies of disaster risk reduction. This is the only volume to consider the earthquake and volcanic histories of the Azores across the whole archipelago and is based, not only on contemporary published research, but also on the detailed study of archival source materials. The authors seek to show how extreme environmental events, as expressed through eruptions, earthquakes and related processes operating in the past may be considered using both complementary scientific and social scientific perspectives in order to reveal the ways in which Azorean society has been shaped by both an isolated location in the middle of the Atlantic Ocean and the ever present threat of environmental uncertainty. Chapter 2, which analyses in depth the geology and tectonics of the islands is of more specialist interest, but technical terms are fully explained so as to widen the accessibility of this material. The audience for this volume includes all those who are interested in the geology, geography, history and hazard responses in the Azores. It is written, not just for the educated general reader, but for the specialist earth scientist and hazard researcher.

Though the Earth's outermost shell is comprised of tectonic plates that are constantly shifting underneath our feet, the ground is usually quiet and still. But sometimes, an earthquake violently rocks the ground or an explosive volcanic blast causes destruction to surrounding areas. Yet despite the potential devastating effects, earthquakes and volcanoes also help create the land people live on. Earthquakes and Volcanoes explains what triggers earthquakes and volcanic eruptions, where on Earth they are most likely to occur, how they happen, and how examining disasters of the past can make people safer in the future during these events.

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.

Some of the planet’s most destructive forces—including earthquakes and volcanic activity—are caused by the same factors that helped shape much of the Earth as it is today. Plate tectonics, or movement of the Earth’s outer layers, can occur in a number of different ways and produce a range of results, some minor and others far more considerable or devastating. Distinct maps, interesting sidebars, and annotated illustrations of the Earth’s layers are included in this volume, which details the motion of the planet and the nature and study of both earthquakes and volcanoes.

Volcanic eruptions have killed thousands of people and damaged homes, villages, infrastructure, subsistence gardens, and hunting and fishing grounds in Papua New Guinea and the Solomon Islands. The central business district of a town was destroyed by a volcanic eruption in the case of Rabaul in 1994. Volcanic disasters litter not only the recent written history of both countries—particularly Papua New Guinea—but are recorded in traditional stories as well. Furthermore, evidence for disastrous volcanic eruptions many times greater than any witnessed in historical times is to be found in the geological record. Volcanic risk is greater today than at any time previously because of larger, mainly sedentary populations on or near volcanoes in both countries. An attempt is made in this book to review what is known about past volcanic eruptions and disasters with a view to determining how best volcanic risk can be reduced today in this tectonically complex and volcanically threatening region.

This full-color, dynamically illustrated volume helps readers better understand the causes of fractures and the magnitude and violence of the forces deep within the earth. It contains shocking scenes of cities convulsed by earthquakes and volcanoes, natural phenomena that, in mere seconds, unleash rivers of fire; destroy buildings, highways, bridges, and gas and water lines; and leave entire cities without electricity or phone service. Earthquakes near coastlands can cause tsunamis, waves that spread across the ocean with the speed of an airplane. A tsunami that reaches a coast can be more destructive than the earthquake itself. All of this fierce dynamism is brought into vivid focus here with stunning photographs, cutaway diagrams, and information-packed infographics.
