The mechanical behaviour and failure modes of volcanic rocks: a review

  title={The mechanical behaviour and failure modes of volcanic rocks: a review},
  author={Michael J. Heap and Marie E. S. Violay},
  journal={Bulletin of Volcanology},
The microstructure and mineralogy of volcanic rocks is varied and complex, and their mechanical behaviour is similarly varied and complex. This review summarises recent developments in our understanding of the mechanical behaviour and failure modes of volcanic rocks. Compiled data show that, although porosity exerts a first-order influence on the uniaxial compressive strength of volcanic rocks, parameters such as the partitioning of the void space (pores and microcracks), pore and crystal size… 

Experimental investigation of pore-fracture relationship on failure behaviour of porous rock materials

Fracturing leading to the failure of rock material is related to the inherent properties of the rock, such as pores with different peculiarities. Most of the studies focusing on the effect of

The Permeability of Porous Volcanic Rock Through the Brittle‐Ductile Transition

The permeability of volcanic rock controls the distribution of pore fluids and pore fluid pressure within a volcanic edifice, and is therefore considered to influence eruptive style and volcano

Volcanic rock masses exhibit temporal and spatial variability, even at the scale and duration of engineering projects. Volcanic processes are dynamic, resulting in rock masses ranging from

Damage amplification during repetitive seismic waves in mechanically loaded rocks

Cycles of stress build-up and release are inherent to tectonically active planets. Such stress oscillations impart strain and damage, prompting mechanically loaded rocks and materials to fail. Here,

Pore Space Topology Controls Ultrasonic Waveforms in Dry Volcanic Rocks

Pore space controls the mechanical and transport properties of rocks. At the laboratory scale, seismic modeling is usually performed in relatively homogeneous settings, and the influence of the pore

Calculating the cohesion and internal friction angle of volcanic rocks and rock masses

Rock failure criteria are key input parameters for models designed to better understand the stability of volcanic rock masses. Cohesion and friction angle are the two defining material variables for

Rheological Controls on Magma Reservoir Failure in a Thermo‐Viscoelastic Crust

As volcanoes undergo unrest, understanding the conditions and timescales required for magma reservoir failure, and the links to geodetic observations, are critical when evaluating the potential for

Whole-rock oxygen isotope ratios as a proxy for the strength and stiffness of hydrothermally altered volcanic rocks

Hydrothermal alteration is considered to increase the likelihood of dome or flank collapse by compromising stability. Understanding how such alteration influences rock properties, and providing

Hidden mechanical weaknesses within lava domes provided by buried high-porosity hydrothermal alteration zones

Catastrophic lava dome collapse is considered an unpredictable volcanic hazard because the physical properties, stress conditions, and internal structure of lava domes are not well understood and can



Failure criteria for porous dome rocks and lavas: a study of Mt. Unzen, Japan

Abstract. The strength and macroscopic deformation mode (brittle vs. ductile) of rocks is generally related to the porosity and pressure conditions, with occasional considerations of strain rate. At

Fracture and compaction of andesite in a volcanic edifice

The experiments show that, at shallow depths, both low- and high-porosity lavas dilate and fail by shear fracturing, but deeper in the edifice, the failure of high- porosity lava is compactant and driven by cataclastic pore collapse, and the implication of these data is that sidewall outgassing may be efficient in the shallow Edifice, where rock can fracture, but may be impeded deeper inThe edifice due to compaction.

Micromechanics of brittle faulting and cataclastic flow in Mount Etna basalt

Understanding how the strength of volcanic rocks varies with stress state, pressure, and microstructural attributes is fundamental to understanding the dynamics and tectonics of a volcanic system and

Mechanical behavior and localized failure modes in a porous basalt from the Azores

Basaltic rocks are the main component of the oceanic upper crust, thus of potential interest for water and geothermal resources, storage of CO2and volcanic edifice stability. In this work, we

Compaction, dilatancy, and failure in porous carbonate rocks

[1] The analysis of dilatant and compactant failure in many sedimentary and geotechnical settings hinges upon a fundamental understanding of inelastic behavior and failure mode of porous carbonate

Microstructural controls on the physical and mechanical properties of edifice‐forming andesites at Volcán de Colima, Mexico

The reliable assessment of volcanic unrest must rest on an understanding of the rocks that form the edifice. It is their microstructure that dictates their physical properties and mechanical behavior
