Energy Partitioning, Dynamic Fragmentation, and Off‐Fault Damage in the Earthquake Source Volume
Seismological fracture or breakdown energy represents energy expended in a volume surrounding the advancing rupture front and the slipping fault surface. Estimates are commonly obtained by inverting


Mechanical properties of quartz at the α‐β phase transition: Implications for tectonic and seismic anomalies
The anelastic response of single‐crystal and polycrystalline quartz and quartz‐rich sandstones to applied stress at low frequencies has been investigated by dynamic mechanical analysis and force
Effect of high-low quartz transition on compressional and shear wave velocities in rocks under high pressure
The compressional and shear wave velocities in quarzite, granite, and granulite are determined at a fixed confining pressure of 2 kb as a function of temperature up to 720° C. The high-low quartz
The Effects of Earthquakes and Fluids on the Metamorphism of the Lower Continental Crust
Rock rheology and density have first‐order effects on the lithosphere's response to plate tectonic forces at plate boundaries. Changes in these rock properties are controlled by metamorphic
Grain-scale pressure variations and chemical equilibrium in high-grade metamorphic rocks
In the classical view of metamorphic microstructures, fast viscous relaxation (and so constant pressure) is assumed, with diffusion being the limiting factor in equilibration. This contribution is
Possible influence of polymorphic transitions in minerals (according to the quartz example) on seismotectonic processes in the lithosphere
The thermally activated physical processes essential for earthquake source physics and the formation of mylonite layers and deep shear zones are examined. The possibility of the influence of
α/β phase transition in quartz monitored using acoustic emissions
SUMMARY It is usually suggested that thermal cracking in a quartz-bearing rock results from the anomalously high volumetric expansion coefficients of quartz (e.g. Simmons & Cooper 1978). It has also
