Catastrophic collapses of steep volcano flanks threaten many populated regions, and understanding factors that promote collapse could save lives and property. Large collapses of hydrothermally al- tered parts of Mount Rainier have generated far-traveled debris flows; future flows would threaten densely populated parts of the Puget Sound region. We evaluate edifice collapse hazards at Mount Rainier using a new three-dimensional slope stability method incorporating detailed geologic mapping and…

Massive collapse of volcano edifices triggered by hydrothermal pressurization

Catastrophic collapse of steep volcano flanks threatens lives at stratovolcanoes around the world. Although destabilizing shallow intrusion of magma into the edifice accompanies some collapses (e.g.,

Volcano collapse promoted by progressive strength reduction: new data from Mount St. Helens

Rock shear strength plays a fundamental role in volcano flank collapse, yet pertinent data from modern collapse surfaces are rare. Using samples collected from the inferred failure surface of the

Volcano electrical tomography unveils edifice collapse hazard linked to hydrothermal system structure and dynamics

A high-resolution, three-dimensional electrical conductivity model of the La Soufrière de Guadeloupe volcano is derived from extensive electrical tomography data and several highly conductive regions in the lava dome that are associated to fluid saturated host-rock and preferential flow of highly acid hot fluids within the dome are identified.

Summit acid crater lakes and flank instability in composite volcanoes

Volcanic landslides, including flank and sector collapses, constitute a major hazard in many parts of the world. While composite volcanoes are innately unstable, the presence of a hydrothermal system


Massive rock failures pose one of the greatest hazards at stratovolcanoes; more than 20,000 fatalities have resulted worldwide from historical volcano edifice collapses. Although numerous processes

Geophysical modeling of collapse‐prone zones at Rumble III seamount, southern Pacific Ocean, New Zealand

Catastrophic collapses of submarine volcanoes have the potential to generate major tsunami, threatening many coastal populations. Recognizing the difficulties surrounding anticipations of these

Three-dimensional geophysical mapping of rock alteration and water content at Mount Adams, Washington : Implications for lahar hazards

[1] Hydrothermally altered rocks, particularly if water saturated, can weaken stratovolcanoes, thereby increasing the potential for catastrophic sector collapses that can lead to far-traveled,

Catastrophic sector collapse at Usu volcano, Hokkaido, Japan: failure of a young edifice built on soft substratum

Catastrophic sector collapse is a destructive volcanic process that occurs during the growth history of a volcano. Understanding the timing and causal mechanisms of sector collapse at individual



Aerogeophysical measurements of collapse-prone hydrothermally altered zones at Mount Rainier volcano

Hydrothermally altered rocks can weaken volcanoes, increasing the potential for catastrophic sector collapses that can lead to destructive debris flows. Evaluating the hazards associated with such

Catastrophic collapse at stratovolcanoes induced by gradual volcano spreading

Unlike ordinary mountains, which are formed by slow uplift and erosion, volcanoes are constructed rapidly. As a consequence, many are liable to massive flank failures, leading to debris avalanches

Sector collapse forming at Casita volcano, Nicaragua

Catastrophic sector collapse occurs when a volcano becomes structurally unable to support its own load. One process particularly capable of weakening the edifice is hydrothermal activity. It can

Failure of volcano slopes

Magmatic intrusions can initiate and sustain massive and catastrophic volcano collapse. Their role is twofold, involving both driving and resisting forces. First, flank stability is diminished by

Rock Mass Strength Assessment and Significance to Edifice Stability, Mount Rainier and Mount Hood, Cascade Range Volcanoes

Abstract—Catastrophic edifice and sector failure occur commonly on stratovolcanoes worldwide and in some cases leave telltale horseshoe-shaped calderas. Many of these failures are now recognised as

Debris flow, debris avalanche and flood hazards at and downstream from Mount Rainier, Washington

Mount Rainier volcano has produced many large debris flows and debris avalanches during the last 10,000 years. These flows have periodically traveled more than 100 kilometers from the volcano to

Abstract Active volcanoes are revealed to be dynamically evolving structures, the growth and development of which are characteristically punctuated by episodes of instability and subsequent

Volcanic hazards from Bezymianny- and Bandai-type eruptions

Major slope failures are a significant degradational process at volcanoes. Slope failures and associated explosive eruptions have resulted in more than 20 000 fatalities in the past 400 years; the

Dynamic basis of volcanic spreading

The established models of the structure and dynamics of a “typical” Hawaiian volcano lead inevitably to a paradox: finite element viscoelastic calculations, using TECTON [Melosh and Raefsky, 1980,

Catastrophic Volcanic Collapse: Relation to Hydrothermal Processes

Hot spring water compositions, residence times, and flow paths through faults were used to model potential collapse at Ruiz and Caldera dimensions, deposits, and alteration mineral volumes are consistent with parameters observed at other volcanoes.
