Volcanic Ash: Hazard Observation presents an introduction followed by four sections, each on a separate topic and each containing chapters from an internationally renowned pool of authors. The introduction provides a volcanological context for ash generation that sets the stage for the development and interpretation of techniques presented in subsequent sections. The book begins with an examination of the methods to characterize ash deposits on the ground, as ash deposits on the ground have generally experienced some atmospheric transport. This section will also cover basic information on ash morphology, density, and refractive index, all parameters required to understand and analyze assumptions made for both in situ measurements and remote sensing ash inversion techniques. Sections two, three, and four focus on methods for observing volcanic ash in the atmosphere using ground-based, airborne, and spaceborne instruments respectively. Throughout the book, the editors showcase not only the interdisciplinary nature of the volcanic ash problem, but also the challenges and rewards of interdisciplinary endeavors. Additionally, by bringing together a broad perspective on volcanic ash studies, the book not only ties together ground-, air-, academic, and applied approaches to the volcanic ash problem, but also engages with other scientific communities interested in particulate transport. Includes recent case studies highlighting the impact of volcanic ash, making methods used for observation more accessible to the reader Contains advances in volcanic ash observation that can be used in other remote sensing applications Presents a cross-disciplinary approach that includes not only methods of tracking and measuring ash in the atmosphere, but also of the fundamental science that supports methodological application and interpretation Edited by an internationally recognized team with a range of expertise within the field of volcanic ash

This conference was prompted by the occurrence of 5 encounters between passenger jetliners with drifting clouds of volcanic ash from the 1989-90 eruptions of Redoubt Volcano in Alaska. Examines 5 principal areas, including: how volcanoes produce ash clouds, the damage and impacts resulting from ash-cloud encounters, communications procedures for mitigating the risks from volcanic ash, the meteorology and modeling of ash-cloud movement, and methods for detection and tracking of ash clouds. 60 technical presentations are included.

While the majority of studies on volcanic ash in Ecuadorian archaeology are focused on tephrochronology or regional abandonment, there has yet to be a study conducted on the different technical and ritual applications of volcanic ash. Volcanic ash has a great deal of unique chemical and physical properties that make it ideal for a wide variety of technical uses. These same properties make volcanic ash useful for a number of analyses that can yield clues to ancient technical knowledge, areas of influence, and systems of exchange. As a distinctive byproduct closely associated with devastating volcanic eruptions, volcanic ash held great symbolic significance and was used for many ritual applications as well. The ways in which ash was used in these ritual settings can yield clues to ancient conceptions of volcanos and the intricacies of human-volcano relationships. Because volcanic ash was used by various cultures for different purposes, archaeological remains of these uses can serve as culturally and temporally diagnostic markers in the archaeological record. This thesis seeks to catalog these different uses so that they might serve as a reference for other researchers examining volcanic ash features and to discuss them in such a way that it might better our understanding of the complicated relationship ancient people had with these most imposing features of the landscape.

Volcanic eruptions are generally viewed as agents of destruction, yet they provide the parent materials from which some of the most productive soils in the world are formed. The high productivity results from a combination of unique physical, chemical and mineralogical properties. The importance and uniqueness of volcanic ash soils are exemplified by the recent establishment of the Andisol soil order in Soil Taxonomy. This book provides the first comprehensive synthesis of all aspects of volcanic ash soils in a single volume. It contains in-depth coverage of important topics including terminology, morphology, genesis, classification, mineralogy, chemistry, physical properties, productivity and utilization. A wealth of data (37 tables, 81 figures, and Appendix) mainly from the Tohoku University Andisol Data Base is used to illustrate major concepts. Twelve color plates provide a valuable visual-aid and complement the text description of the world-wide distribution for volcanic ash soils. This volume will serve as a valuable reference for soil scientists, plant scientists, ecologists and geochemists interested in biogeochemical processes occurring in soils derived form volcanic ejecta.

The symposium's aims were to encourage improvements in the detection, tracking, and warning of volcanic ash hazard so that aircraft may avoid ash clouds, and to review the effects of volcanic ash on aircraft so that pilots who encounter ash can respond appropriately.

This report describes a study of the feasibility of employing certain volcanic ashes, found in Iceland, in combination with lime and gypsum to produce strong, durable building materials. The researchers learned, during a visit to Iceland, that mortars made of volcanic ash and lime were used in the construction of many of the early stone buildings in Iceland. These mortars were found to be very strong or rock like and durable having survived for periods of 90 to 400 years.
