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.
A description of rocks and structures in the region of the imbricate front of the Sapphire thrust plate, from a reconnaissance study.
Understanding the physical behavior of volcanoes is key to mitigating the hazards active volcanoes pose to the ever-increasing populations living nearby. The processes involved in volcanic eruptions are driven by a series of interlinked physical phenomena, and to fully understand these, volcanologists must employ various physics subdisciplines. This book provides the first advanced-level, one-stop resource examining the physics of volcanic behavior and reviewing the state-of-the-art in modeling volcanic processes. Each chapter begins by explaining simple modeling formulations and progresses to present cutting-edge research illustrated by case studies. Individual chapters cover subsurface magmatic processes through to eruption in various environments and conclude with the application of modeling to understanding the other volcanic planets of our Solar System. Providing an accessible and practical text for graduate students of physical volcanology, this book is also an important resource for researchers and professionals in the fields of volcanology, geophysics, geochemistry, petrology and natural hazards.
The late author Arysio Santos was a highly regarded climatologist, geologist, and nuclear physicist. He was also a scholar of history, folklore, languages, and the occult. In this groundbreaking study of Atlantis, he draws on all these disciplines, as well as ancient maps, Plato’s dialogues, and folkloric narratives, to provide the most compelling case yet of the disappearance of an entire civilization. Professor Santos demonstrates that Plato’s dating of Atlantis’s disappearance in 11,600 BP (before present) precisely corresponds to the catastrophic end of the Pleistocene Ice Age, as well as a historic flood event of cataclysmic proportions. The rising of the sea level by nearly 500 feet, he argues, submerged continent-sized lands—including Atlantis, which he connects with the biblical Garden of Eden. Provocative chapters cover such topics as the continent’s appearance in ancient maps, Indonesia as the true site of Eden, American interpretations of Atlantis, the four rivers of paradise, and more, giving a clear form to the ghostly outline of this fabled land.
David Stevenson’s new book links the meteorology of the Earth to that of other planets, stars, and clusters of galaxies, showing the similarities and differences between terrestrial weather and that of weather on other worlds. Because Earth is not unique in having weather, there is much to learn from other planets with atmospheres that show the movement of energy from hotter to colder areas. The weather seen on Earth and other known planetary systems are examined to elaborate the connection between climate and the development of life. The weather on Earth and other Solar System planets is a manifestation of the huge energy budget imparted by our star, the Sun, but weather doesn’t stop at...
This book is a collection of papers concerned with the processes and products of magma-sediment mingling and the origin of peperite. Three papers are concerned with physical modelling of magma-wet sediment interaction, whereas the majority of the papers describe a wide variety of peperite compositional and textural types, and discuss controls on their formation. The first paper reviews the current understanding of peperite generation, and serves as an extended introduction to the volume. Peperite is a common rock type generated in many volcanic and sub-volcanic environments. Its study is important for several reasons. Correct identification of peperite is critical in palaeoenvironmental reco...
Rio Grande pueblo societies took shape in the aftermath of significant turmoil and migration in the thirteenth century. In the centuries that followed, the size of Pueblo settlements, level of aggregation, degree of productive specialization, extent of interethnic exchange, and overall social harmony increased to unprecedented levels. Economists recognize scale, agglomeration, the division of labor, international trade, and control over violence as important determinants of socioeconomic development in the modern world. But is a development framework appropriate for understanding Rio Grande archaeology? What do we learn about contemporary Pueblo culture and its resiliency when Pueblo history...
