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 pr

A Historical Perspective on Lateral Collapse and Volcanic Debris Avalanches,ts after 1980 has led to an average of one regional or global debris-avalanche inventory annually in terrestrial or submarine settings and the recognition of a thousand events from nearly 600 volcanoes.

Distribution and Geometric Parameters of Volcanic Debris Avalanche Deposits,is is mainly due to differences in source scar geometry. At the same drop height, VDAs can produce larger volumes because their scars are deeper-seated, more bowl-shaped, and extend along longer slopes than is common for rock slopes.

Volcanic Debris Avalanche Transport and Emplacement Mechanisms,the base, bulldozing and incorporation of substrata change the composition and behaviour of the VDA. In extreme cases, VDAs transform into lahars if sufficient water is available for entrainment.

Their unique composition, grain sizes, and abundance of matrix sets VDADs apart from deposits of large rockslides and debris flows. Th
