The Santiaguito Volcanic Dome Complex Guatemala

"This volume is a sampling of current scientific work about volcanoes in Central America with specific application to hazards. The papers reflect a variety of international and interdisciplinary collaborations and employ new methods. The book will be of interest to a broad cross section of scientists, especially volcanologists. The volume also will interest students who aspire to work in the field of volcano hazards mitigation or who may want to work in one of Earth's most volcanically active areas."--Publisher's website.

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.

This book highlights major problems in the statistical analysis of compositions that have been known for over a century, as well as the corresponding solutions that have been put forward by specialists over the past 30 years. The basic assumptions of normality or multi-normality are pointed out and methods to test and achieve them are also covered. The conventional major and trace element geochemistry and modeling equations are discussed, and are followed by a more sophisticated multidimensional approach to data handling. The book’s main focus is on the use of statistical techniques to facilitate data interpretation. It also highlights the classification (or nomenclature) and tectonic discrimination aspects for both igneous and sedimentary rocks. The book concludes by discussing computer programs that are helping pave the way from geochemistry to geochemometrics. Written by a leading expert in the area of geochemistry, it offers a valuable guide for students and professionals in the area.

Volcanic eruptions are complex and inherently uncertain, making the management of a potentially explosive eruption on a small island with limited resources extremely difficult. This volume presents scientific findings from the 2020–21 eruption of La Soufrière Volcano, on the island of St Vincent in the Eastern Caribbean. This involved three months of effusive activity that escalated rapidly to 13 days of explosive activity, beginning with an intense two days of near-continuous ash venting and explosions. The book contains an introduction and 17 papers, split into two parts: the first presents geological and volcanological advances, whereas the second documents and analyses the impacts of the eruption and the challenges presented for the management of the volcanic crisis. This volume represents both significant contributions to the knowledge of the Soufrière eruptive system and important insights into the ways and means by which volcanic eruptions of this type impact on populations at risk. It also provides detailed insights into the most effective communication processes through this type of crisis.
