Includes bibliographical references (p. 270-292) and index. - The increase in the number of earthquakes and in the temperature of the hot springs that occurred between 1995 and 1997 on the islands of Saba and St. Eustatius, located in the Northern Lesser Antilles, was more than a mere fluke in subterranean activity: a mild volcano-seismic crisis had produced an increased heat flow. This book contains the results of a profound study of Saba and the Quill, St. Eustatius, which provides a firm basis for the conclusion that both volcanoes are indeed active. The results were classified as confidential for very many years but at last are published for the first time here in full. Both authors strongly recommend routine monitoring on both densely populated islands and education of local island populations in understanding their volcanic hazards. Condition : as new copy.

Hardcover. Zustand: New. v, 101 pages : illustrations, maps ; 29 cm. Providencia is the only example of subaerial volcanism on the Lower Nicaraguan Rise. In this volume, the authors examine this volcanism and the geological history of the western Caribbean and the Lower Nicaraguan Rise, whose origin and role in the development of the Caribbean plate has been described as enigmatic and poorly understood. While the Providencia alkaline suite is similar to others within the Western Caribbean Alkaline Province, its subalkaline suite is unique, having no equivalent within the province. In order to unravel its complex history and evolution, this volume presents new and previously published results for the geology, geochemistry, petrology, and isotopic ages from the Providencia island group.
