How do mountains grow underwater? Why does the "Ring of Fire" feature so many volcanoes? Why might the island of Surtsey soon disappear? This series explores the causes and effects that shape our world. From the underwater volcanoes that sprout into islands, to the rushing waterfalls that spark electric currents, this series demonstrates how both natural and man-made phenomena occur.

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.

Did you know that coral reefs and volcanoes have a very interesting connection? An atoll is a coral island surrounding a lagoon. Atolls are formed when a reef grows around a sinking volcanic island. This book explores the relationship between volcanoes and reefs and the "life" cycle of a volcanic island. Full-color photographs provide readers with connections to the narrative and fact boxes and sidebars further explain this topic.

As both individuals and societies, we are making decisions today that will have profound consequences for future generations. From preserving Earth's plants and animals to altering our use of fossil fuels, none of these decisions can be made wisely without a thorough understanding of life's history on our planet through biological evolution. Companion to the best selling title Teaching About Evolution and the Nature of Science, Evolution in Hawaii examines evolution and the nature of science by looking at a specific part of the world. Tracing the evolutionary pathways in Hawaii, we are able to draw powerful conclusions about evolution's occurrence, mechanisms, and courses. This practical book has been specifically designed to give teachers and their students an opportunity to gain a deeper understanding of evolution using exercises with real genetic data to explore and investigate speciation and the probable order in which speciation occurred based on the ages of the Hawaiian Islands. By focusing on one set of islands, this book illuminates the general principles of evolutionary biology and demonstrate how ongoing research will continue to expand our knowledge of the natural world.

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.

Ocean island volcanoes constitute some of the most prominent and rapidly-formed features on Earth, and yet they cannot be explained by conventional plate tectonics. Although typically associated with intraplate settings (hotspots), these volcanoes also occur in different geodynamic settings (near mid-ocean ridges). The nature of ocean island magmatism is still the subject of intense debate within the geological community. Traditionally it has been linked to the presence of mantle plumes at depth (e.g. Hawaii), although the interaction with plate tectonics is also recognized to play a significant role (e.g. Azores, Galápagos). Magma compositions may range from basaltic to more differentiated, which consequently is accompanied by striking changes in the eruption style from effusive-dominated to highly explosive volcanism. Understanding how these magmas evolve and how volcanic processes act at ocean island volcanoes are key issues of modern volcanology. Moreover, the growth of ocean island volcanoes from their rise on the seafloor as seamounts, to island emergence and subsequent formation of shield volcanoes (and in some cases large caldera volcanoes) is governed by multiple interrelated changes. It is well known that competing processes model ocean island volcanoes during alternating and/or coeval periods of construction and destruction. The geological evolution of these volcanoes results from the balance among volcanism, intrusions, tectonics, subsidence/uplift, mass wasting, sedimentation, and subaerial and wave erosion. A better knowledge of the interplay between these processes is crucial to obtain a more comprehensive understanding of the evolution of such volcanoes, and to the eventual formulation of a unified model for ocean island evolution. Ocean islands are especially vulnerable to volcanic eruptions and other geological hazards on account of their typical small size, rough topography and isolation, which make risk management and evacuation difficult. Volcanic eruptions, in particular, may have a significant impact on local populations, infrastructures, economy and even on the global climate. It is therefore fundamental to monitor these volcanoes with complementary geophysical, geodetic and geochemical techniques in order to forecast future eruptions and their impacts. However, the assessment of volcanic hazards on ocean islands is challenging due to the large variety of phenomena involved (e.g. lava flows, tephra fallout, pyroclastic density currents, lahars, gas emissions). Different approaches are used to assess volcanic hazards, either based on empirical methods or sophisticated numerical models, focusing on a single phenomenon or the combination of different hazards. This Frontiers Research Topic aims to promote discussion within the scientific community, representing an important step forward in our knowledge of ocean island volcanoes in order to serve as a reference for future research.

Laki is Iceland's largest volcano. Its eruption in 1783 is one of history's great, untold natural disasters. Spewing out sun-blocking ash and then a poisonous fog for eight long months, the effects of the eruption lingered across the world for years. It caused the deaths of people as far away as the Nile and created catastrophic conditions throughout Europe. Island on Fire is the story not only of a single eruption but the people whose lives it changed, the dawn of modern volcanology, as well as the history and potential of other super-volcanoes like Laki around the world. And perhaps most pertinently, in the wake of the eruption of another Icelandic volcano, Eyjafjallajokull, which closed European air space in 2010, acclaimed science writers Witze and Kanipe look at what might transpire should Laki erupt again in our lifetime.
