Preexisting faults exert a dominant control on frictional strength and stability of crustal faults.
However, the complex interplay between fault and host rocks and their influences on …

Catastrophic landslides, which often occur abruptly after months or years of creep, threaten
mountain safety. Hence, comprehensive prediction of catastrophic landslides is necessary …

We ran an extensive series of shear experiments to test the effect of shear velocity and
normal stress on wear-rate and frictional strength. The experiments were conducted on three …

The experimental shearing of granitic faults revealed complex evolution of strength and
microstructure. We use a rotary shear apparatus to shear three types of granitic rocks at …

Seismic analyses show that slip during large earthquakes evolves in a slip-pulse mode that
is characterized by abrupt, intense acceleration followed by moderate deceleration. We …

For millennia, human‐made machinery incorporated rolls and wheels to reduce frictional
resistance, yet similar elements are practically absent in natural systems. We found in rock …

Slip during large earthquakes occurs along faults that are hundreds of kilometers long (eg,
San Andreas fault, Alpine fault), yet, the dynamic weakening that drives these earthquakes is …

Shear along rock faults is always associated with wear of the sliding blocks that commonly
results in the production of fine powder called gouge. We experimentally analyzed intensity …

Earthquakes are events of unstable shear rupture that propagate along faultzones in the
crust. Earthquake rupture processes have been the focus of many theoretical studies …
