The 1995 to present eruption of Soufrière Hills Volcano on Montserrat is one of the most important and best-studied eruptions of an explosive andesitic volcano. This volume presents scientific findings from the period between 2000 and 2010; it follows on from Memoir 21, which focused on the early years of activity between 1995 and 1999. In addition to descriptions and analysis of the growth, collapse and explosions associated with lava domes, there are papers on the deformation of the volcano caused by the deep magma, the petrology and geochemistry of the lavas and associated gases. Of particular note are: an overview of the insights into the deep structure of the volcano that resulted from a major international seismic tomography experiment; and an analysis of the quantitative risk assessment process that has run now for most of the eruption, the longest such continuous assessment in the world.

Montserrat is a small island in the Leeward islands of the eastern Caribbean and at present a British Overseas Territory. It has suffered greatly in recent times, first from the devastations of Hurricane Hugo in 1989 and since 1995 from the still-ongoing eruption of the Soufrière Hills volcano that has caused two-thirds of the island’s population to emigrate and left half the island a dangerous exclusion zone. Archaeological research here began only in the late 1970s, but work over the past four decades has now made it possible to present an archaeological history of Montserrat, from the earliest known traces of human activity on the island about 5,000 years ago to the present. This book draws on all the available archaeological evidence (including that from the co-authors’ own island-wide survey and excavation project since 2010), as well as newly available archival documents, to trace this little island’s long history and heritage. This is not the story of an isolated and remote island: Montserrat is shown rather to be a place intricately connected to the flows of people and goods that have travelled between islands and across the Atlantic at various points in time, both Amerindian and historical. Despite its small size and seeming irrelevance, Montserrat has in fact always been networked into regional and global systems of connectivity. An underlying theme of this volume is resilience. It presents insights from the archaeological and documentary evidence on how the island’s inhabitants have coped with often adverse conditions throughout the course of its history – hurricanes, volcanic eruptions, slavery, disease, invasions, and impoverishment – all while remaining proudly connected to heritage that celebrates the accomplishments of island residents.

The andesitic dome-building eruption of the Soufrière Hills Volcano wreaked havoc on the small Caribbean island of Montserrat. About half of this 'emerald Isle' was rendered barren and uninhabitable, almost two-thirds of the original population had to leave, and 19 lives were lost, all as a direct result of the volcanic activity. This papers in this volume address the chronology, dynamics, products and associated hazards of the eruption.

Two-thirds of Montserrat, the author's homeland, has been devastated by continuous eruptions of the Soufriere Hills volcanoes. Montserrat is a small Island of the Leeward Islands of the Caribbean, just forty square miles, but it has seven active volcanoes. In Montserrat on My Mind, the author has included several stories of Montserrat before the eruptions, and some during the crisis. Some stories have a tint of mystery, others a touch of Montserrat's humor, but all generally tell tales of Montserrat with a Caribbean flavor. There are three poems which relate to the volcano and the author's prayerful hope that Montserrat will rise again from the tons of magma that have buried so many of its picturesque villages, including its capital, the once thriving Plymouth. The author's Village, Kinsale, exists no more. Unfortunately, Montserrat was almost anonymous before its volcanic eruptions. Now, it is an open laboratory for volcanologists, a vacation haven for videographers, and curiosity seekers. They know Montserrat as a gray land drooping under the weight of pyroclastic flow, but the author remembers it as The Emerald Isle of the Caribbean, where the serrated mountains stood like green giants in the Caribbean scenery.

Volcanic seismology represents the main, and often the only, tool to forecast volcanic eruptions and to monitor the eruption process. This book describes the main types of seismic signals at volcanoes, their nature and spatial and temporal distributions at different stages of eruptive activity. Following from the success of the first edition, published in 2003, the second edition consists of 19 chapters including significant revision and five new chapters. Organized into four sections, the book begins with an introduction to the history and topic of volcanic seismology, discussing the theoretical and experimental models that were developed for the study of the origin of volcanic earthquakes. The second section is devoted to the study of volcano-tectonic earthquakes, giving the theoretical basis for their occurrence and swarms as well as case stories of volcano-tectonic activity associated with the eruptions at basaltic, andesitic, and dacitic volcanoes. There were 40 cases of volcanic eruptions at 20 volcanoes that occurred all over the world from 1910 to 2005, which are discussed. General regularities of volcano-tectonic earthquake swarms, their participation in the eruptive process, their source properties, and the hazard of strong volcano-tectonic earthquakes are also described. The third section describes the theoretical basis for the occurrence of eruption earthquakes together with the description of volcanic tremor, the seismic signals associated with pyroclastic flows, rockfalls and lahars, and volcanic explosions, long-period and very-long-period seismic signals at volcanoes, micro-earthquake swarms, and acoustic events. The final section discuss the mitigation of volcanic hazard and include the methodology of seismic monitoring of volcanic activity, the examples of forecasting of volcanic eruptions by seismic methods, and the description of seismic activity in the regions of dormant volcanoes. This book will be essential for students and practitioners of volcanic seismology to understand the essential elements of volcanic eruptions. - Provides a comprehensive overview of seismic signals at different stages of volcano eruption. - Discusses dozens of case histories from around the world to provide real-world applications. - Illustrations accompany detailed descriptions of volcano eruptions alongside the theories involved.

This open access book summarizes the findings of the VUELCO project, a multi-disciplinary and cross-boundary research funded by the European Commission's 7th framework program. It comprises four broad topics: 1. The global significance of volcanic unrest 2. Geophysical and geochemical fingerprints of unrest and precursory activity 3. Magma dynamics leading to unrest phenomena 4. Bridging the gap between science and decision-making Volcanic unrest is a complex multi-hazard phenomenon. The fact that unrest may, or may not lead to an imminent eruption contributes significant uncertainty to short-term volcanic hazard and risk assessment. Although it is reasonable to assume that all eruptions are associated with precursory activity of some sort, the understanding of the causative links between subsurface processes, resulting unrest signals and imminent eruption is incomplete. When a volcano evolves from dormancy into a phase of unrest, important scientific, political and social questions need to be addressed. This book is aimed at graduate students, researchers of volcanic phenomena, professionals in volcanic hazard and risk assessment, observatory personnel, as well as emergency managers who wish to learn about the complex nature of volcanic unrest and how to utilize new findings to deal with unrest phenomena at scientific and emergency managing levels.
