A landmark study in volcanology, 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.
Heavily illustrated with figures, photos and tables of chemical composition of volcanic rocks from the islands of the Northern Lesser Antilles and specimen lists for Saba and St. Eustatius. This book comes in an exclusive case with five large maps of the region, two of them in full-colour, which offer a wealth of detailed information and which were prepared especially for this publication.
This magnificent volume is the latest work of a collaborative effort by the authors that has extended for over thirty years. M. John Roobol is a technical advisor to the Saudi Geological Survey and Alan L. Smith is professor of geological sciences at California State University, San Bernardino. Both authors originate in South Wales, UK and met coincidentally early in their careers, when they independently decided to carry out the same study on the same volcano, on Mt. Pelique in 19. eeof many collaborative studies that led them to write about the geology of almost all of the Caribbean islands, especially those with volcanic rocks.
