This book presents an overview of volcanic debris avalanche deposits, which are produced by partial volcanic edifice collapse, a catastrophic natural phenomenon. It has been 40 years since the volcanic debris avalanche associated with the 1980 eruption of Mount St. Helens, and our understanding of these events has grown considerably in the interim. Drawing on these advances, the book addresses all aspects of volcanic debris avalanches. Though previously overlooked in field-based geological and volcanological studies, these deposits are now known to be associated with most volcanoes and volcanic areas around the world. The book presents state-of-the-art ideas on the triggering and emplacement mechanisms of these events, supported by field and analogue studies, as well as new simulations tools and models used to determine their physical characteristic and hazards.

Catastrophic collapse of volcanic edifices is a relatively common phenomenon in the geological record, representing the largest subaeriallandsliding events on Earth. Subsequent volcanic debris avalanche (VDA) runout lengths often exceed 50 km and inundated areas may be greater than 1,000 km2. The geomechanical processes that occur during emplacement, however, remain poorly understood as emplacement processes must generally be inferred from deposit analysis. Summarizing the literature, this thesis first introduces the general factors that control edifice collapse, mechanisms thought to control avalanche mobility and commonly observed deposit features. The mechanisms which have led to the formation of characteristic deposit features specifically are then reviewed; commonly discussed themes are then used to develop a general emplacement model which summarizes the geomechanical evolution of VDAs. This model is then tested by analyzing orthophotographic images of VDA deposits; common deposit morphologies are observed in each case, suggesting a common deformation sequence may occur during emplacement. To better understand emplacement processes, a distinct element numerical model is then created. Initial unbonded particulate avalanche simulations allow spatial/temporal variations in avalanche body stress, energy and deformation to be considered in relation to the development of characteristic deposit features. A more sophisticated bonded particle model is then utilized to allow the consideration of emerging brittle behaviour. Resulting simulations display the development of characteristic VDA deposit features from initial block sliding and horst and graben development. Evolution to a fully-flowing granular avalanche occurs through the initiation and propagation of faults generated due to stresses in the avalanche body, reflective of the proposed common deformation sequence. Features commonly observed in VDA deposits, such as toreva blocks and surface hummocks, are created in the bonded avalanche simulations. Use of this innovative numerical model therefore allows for new insight into the geomechanical evolution of rock and debris avalanches to be developed.

Landslide Hazards, Risks and Disasters Second Edition makes a broad but detailed examination of major aspects of mass movements and their consequences, and provides knowledge to form the basis for more complete and accurate monitoring, prediction, preparedness and reduction of the impacts of landslides on society. The frequency and intensity of landslide hazards and disasters has consistently increased over the past century, and this trend will continue as society increasingly utilises steep landscapes. Landslides and related phenomena can be triggered by other hazard and disaster processes – such as earthquakes, tsunamis, volcanic eruptions and wildfires – and they can also cause other hazards and disasters, making them a complex multi-disciplinary challenge. This new edition of Landslide Hazards, Risks and Disasters is updated and includes new chapters, covering additional topics including rockfalls, landslide interactions and impacts and geomorphic perspectives. Knowledge, understanding and the ability to model landslide processes are becoming increasingly important challenges for society extends its occupation of increasingly hilly and mountainous terrain, making this book a key resource for educators, researchers and disaster managers in geophysics, geology and environmental science. Provides an interdisciplinary perspective on the geological, seismological, physical, environmental and social impacts of landslides Presents the latest research on causality, impacts and landslide preparedness and mitigation. Includes numerous tables, maps, diagrams, illustrations, photographs and video captures of hazardous processes Discusses steps for planning for and responding to landslide hazards, risks and disasters

The contributions in this book were presented, orally or as posters, at the International Volcanological Congress held in New Zealand from 1 to 9 February 1986, the centenary year of the Tarawera eruption of 10 June 1886. More than 500 people, from 29 countries, attend ed the Congress. Most of these works formed part of Symposium 4, "Volcanic Hazards - Prediction and Assess ment", convened by J.H. Latter, R.R. Dibble, D.A. Swanson and C.G. Newhall. The collection represents over half of the published abstracts of Symposium 4, together with three papers given at the Symposium, which lacked abstracts, and two which were part of Symposium 1 on pyroclastic flow deposits. The contribu tions cover a good proportion of the volcanically active parts of the world, with Italy, Japan, the West Indies and the USA especially well represented. Mount Erebus, Vulcano and Rabaul are individual volcanoes which have been treated in particular detail. Unfor tunately, there are no chapters in the book dealing with Africa, the Atlantic islands (except Iceland), Hawaii, Central America (except Mexico), or South America (in spite of the major disaster at Nevado del Ruiz Volcano in 1985).
