This volume aims at providing answers to some puzzling questions concerning the formation and the behavior of collapse calderas by exploring our current understanding of these complex geological processes. Addressed are problems such as:- How do collapse calderas form? - What are the conditions to create fractures and slip along them to initiate caldera collapse and when are these conditions fulfilled? - How do these conditions relate to explosive volcanism?- Most products of large caldera-forming eruptions show evidence for pre-eruptive reheating. Is this a pre-requisite to produce large volume eruptions and large calderas?- What are the time-scales behind caldera processes? - How long does it take magma to reach conditions ripe enough to generate a caldera-forming eruption?- What is the mechanical behavior of magma chamber walls during caldera collapse? Elastic, viscoelastic, or rigid? - Do calderas form by underpressure following a certain level of magma withdrawal from a reservoir, or by magma chamber loading due to deep doming (underplating), or both?- How to interpret unrest signals in active caldera systems?- How can we use information from caldera monitoring to forecast volcanic phenomena?In the form of 14 contributions from various disciplines this book samples the state-of-the-art of caldera studies and identifies still unresolved key issues that need dedicated cross-boundary and multidisciplinary efforts in the years to come. International contributions from leading experts Updates and informs on all the latest developments Highlights hot topic areas and identifies and analyzes unresolved key issues

The Mexican Volcanic Belt is a complex continental-margin volcanic province that crosses central Mexico from the Pacific coast to the Gulf of Mexico coast and forms part of the Pacific Ring of Fire. The book focuses on the calderas in the central portion of this belt, where calderas are more abundant and less well known than those in the eastern and western sectors of the province. Many caldera descriptions are published here for the first time. The calderas and related ignimbrites cover a wide span in time and space, with a Miocene-Pliocene age range. Very interesting magmatic and volcanic processes occur in each particular caldera and each caldera-ignimbrite description is unique. This book gives a description of these various processes and aligns them with what is known globally and provides geoscientists with a better understanding of the regional context of the calderas in the Mexican Volcanic Belt. Describes in detail the large range in textures and compositions of ignimbrites and includes new information about calderas in Mexico Provides a geologic map and stratigraphic type sections of the ignimbrites and associated calderas Summarizes over 20 years of research by the most recognized expert on calderas in Mexico - his expertise on the subject is well recognized internationally

Large caldera collapses represent catastrophic natural events, second only to large meteoritic impacts. In addition, some calderas are densely populated, making the risk extreme, even for moderate eruptions. Understanding caldera mechanisms, unrest and the danger of eruption is therefore a crucial challenge for Earth sciences. Several key features of caldera behaviour have yet to be fully understood. Through a combination of case studies and theoretical modelling, the following topics are addressed in this volume: the conditions required to produce and to release large volumes of magma erupted during caldera formation; how magmatic feeding systems evolve before and after a caldera has formed; the processes that limit the behaviour of precursors to eruptions; how pre-eruptive precursors can be distinguished from those that drive unrest without an eruption; and given that post-collapse eruptions may occur across a wide area, the optimum procedures for designing hazard maps and mitigation strategies.

This memoir synthesizes all the data from the Cambridge, Bristol and Clermont groups, and integrates data from other research groups on the caldera volcanoes of Santorini. It provides interpretations of the tectonic and magmatic evolution of Santorini. The volcanic field has been remapped and a picture of cyclic volcanic activity and magmatic evolution has emerged from this work.

The chapters presented in this International Volcanological Special Issue consider the characteristic features of a single volcano and/or a number of volcanoes worldwide (Jos and Biu Plateau volcanic provinces, Nigeria; Kachchh Rift Zone, Gujarat, India; Guamsan Caldera, Cheongsong, Korea; Somma-Vesuvius volcano, Napoli, Italy) in terms of future volcanic activity. The technical methods used are wide, innovative, as well as classic and reflect the knowledge presented in each chapter. The last chapter, however, deals with a new conceptual and methodological approach for the evaluation of volcanic risk. All these volcanoes (except Somma-Vesuvius volcano) are poorly studied so they deserve more attention, which is the goal of this volcanological book. Further studies are welcome to deepen the knowledge of each of the volcanoes presented.

Teide Volcano has many different meanings: For the Guanche aborigines, who endured several of its eruptions, it was Echeide (Hell). Early navigators had in Teide, a lifesaving widely visible landmark that was towering over the clouds. For the first explorers, Teide was a challenging and dangerous climb, since it was thought that Teide's peak was so high that from its summit the sun was too close and far too hot to survive. Teide was considered the highest mountain in the world at that time and measuring its height precisely was a great undertaking and at the time of global scientific significance. For von Buch, von Humboldt, Lyell and other great 18th and19th century naturalists, Teide helped to shape a new and now increasingly 'volcanic' picture, where the origin of volcanic rocks (from solidified magma) slowly casted aside Neptunism and removed some of the last barriers for the development of modern Geology and Volcanology as the sciences we know today. For the present day population of Tenerife, living on top of the world's third tallest volcanic structure on the planet, Teide has actually become "Padre Teide", a fatherly protector and an emblematic icon of Tenerife, not to say of the Canaries as a whole. The UNESCO acknowledged this iconic and complex volcano, as "of global importance in providing evidence of the geological processes that underpin the evolution of oceanic islands". Today, 'Teide National Park' boasts 4 Million annual visitors including many 'volcano spotters' and is a spectacular natural environment which most keep as an impression to treasure and to never forget. For us, the editors of this book, Teide is all of the above; a 'hell of a job', a navigation point on cloudy days, a challenge beyond imagination, a breakthrough in our understanding of oceanic volcanism that has shaped our way of thinking about volcanoes, and lastly, Teide provides us with a reference point from where to start exploring other oceanic volcanoes in the Canaries and beyond. Here we have compiled the different aspects and the current understanding of this natural wonder.

This study provides innovative mathematical models for assessing the eruption probability and associated volcanic hazards, and applies them to the Campi Flegrei caldera in Italy. Throughout the book, significant attention is devoted to quantifying the sources of uncertainty affecting the forecast estimates. The Campi Flegrei caldera is certainly one of the world’s highest-risk volcanoes, with more than 70 eruptions over the last 15,000 years, prevalently explosive ones of varying magnitude, intensity and vent location. In the second half of the twentieth century the volcano apparently once again entered a phase of unrest that continues to the present. Hundreds of thousands of people live inside the caldera and over a million more in the nearby city of Naples, making a future eruption of Campi Flegrei an event with potentially catastrophic consequences at the national and European levels.
