Large seismogenic faults consist of approximately meter-thick fault cores surrounded by hundreds-of-meters-thick damage zones. Earthquakes are generated rupture propagation and slip within dissipate the stored elastic strain energy in fracture frictional processes zone radiated seismic waves. Understanding this partitioning is fundamental earthquake mechanics to explain dynamic weakening causative operating over different spatial temporal scales. The dissipated along a called or breakdown...
Frictional melt is implied in a variety of processes such as seismic slip, ice skating, and meteorite combustion. A steady state can be reached when continuously produced extruded from the sliding interface, shown recently number laboratory rock friction experiments. thin, low‐viscosity, high‐temperature layer formed resulting low shear resistance. theoretical solution describing coupling heating, thermal diffusion, extrusion obtained, without imposing priori thickness. The traction...

[1] The final slip of about 450 m at 30 m/s the 1963 Vaiont landslide (Italy) was preceded by >3 year long creeping phase which localized in centimeter-thick clay-rich layers (60–70% smectites, 20–30% calcite and quartz). Here we investigate frictional properties under similar deformation conditions as during landslide: 1–5 MPa normal stress, 2 × 10−7 to 1.31 rate displacements up 34 m. Experiments were performed room humidity wet with biaxial, torsion rotary shear apparatus. gouge...
With the advent of high-velocity shear apparatus, several experimental studies have been performed in recent years, improving our understanding evolution fault strength during seismic slip.However, these experiments were conducted under relatively low normal stress (<20 MPa) and using small cylindrical samples where a large gradient slip velocity exists across sliding surface.Given above limitations, extrapolation results to natural conditions is not trivial.Here we present from an study on...

The catastrophic Vaiont landslide (Southern Alps, Italy) of 9 October 1963 moved 2.7 × 10 8 m 3 rock that collapsed in an artificial lake, causing a giant wave killed 1917 people. was preceded by 2–3 years creep ended with the final collapse mass slipping at about 30 s −1 . Assuming localized clay‐rich water‐saturated layer, this study we propose shear heating as primary mechanism for long‐term phase accelerating creep. We only creeping slide, and model using rigid block moving over thin...
Terra Nova, 22, 347–353, 2010 Abstract Thermal pressurization of pore fluid is one the possible mechanisms responsible for dynamic weakening in landslides and earthquakes, but, to date, has not been reproduced laboratory. Here, we report high-velocity experiments performed a rotary shear friction apparatus on smectite-rich gouges from 1963 Vaiont landslide (Italy). The were slid under 1 MPa normal stress, displacements up 30 m slip rate 1.31 s−1 room-humidity water-saturated conditions....
We report systematic spatial variations in fault rocks along nonplanar strike‐slip faults cross‐cutting the Lake Edison Granodiorite, Sierra Nevada, California (Sierran wavy fault) and Lobbia outcrops of Adamello Batholith Italian Alps (Lobbia fault). In case Sierran fault, pseudotachylyte formed at contractional bends, where it is found as thin (1–2 mm) fault‐parallel veins. Epidote chlorite developed same seismic context are especially abundant extensional bends. argue that presence...
