Evidence for and implications of self-healing pulses of slip in earthquake rupture
TLDR
In this article, a qualitative model is presented that produces self-healing slip pulses, which is the key feature of the model is the assumption that friction on the fault surface is inversely related to the local slip velocity, and the model has the following features: high static strength of materials (kilobar range), low static stress drops (in the range of tens of bars).About:

The Mechanics of Earthquakes and Faulting
TL;DR: The connection between faults and the seismicity generated is governed by the rate and state dependent friction laws -producing distinctive seismic styles of faulting and a gamut of earthquake phenomena including aftershocks, afterslip, earthquake triggering, and slow slip events.

Laboratory-derived friction laws and their application to seismic faulting
TL;DR: In this article, a review of the relationship between friction and the properties of earthquake faults is presented, as well as an interpretation of the friction state variable, including its interpretation as a measure of average asperity contact time and porosity within granular fault gouge.

TL;DR: A gradient from near-primary, through old-growth secondary and plantation forests to complete clearance, for eight animal groups in the Mbalmayo Forest Reserve, south-central Cameroon is examined, indicating the huge scale of the biological effort required to provide inventories of tropical diversity, and to measure the impacts of tropical forest modification and clearance.

A review of recent developments concerning the structure, mechanics and fluid flow properties of fault zones
Daniel R. Faulkner,Christopher A.-L. Jackson,Rebecca J. Lunn,Roy W. Schlische,Zoe K. Shipton,Christopher A. J. Wibberley,Martha Oliver Withjack +6 more
TL;DR: Fault zones and fault systems have a key role in the development of the Earth's crust and control the mechanics and fluid flow properties of the crust, and the architecture of sedimentary deposits in basins as discussed by the authors.

Heating and weakening of faults during earthquake slip
TL;DR: In this article, the authors suggest that the most relevant weakening processes in large crustal events are thermal, and to involve thermal pressurization of pore fluid within and adjacent to the deforming fault core, which reduces the effective normal stress and hence also the shear strength for a given friction coefficient.

Acoustic fluidization: A new geologic process?
TL;DR: In this paper, the authors proposed that the low strength apparent in these phenomena are due to a state of "acoustic fluidization" induced by a transient strong acoustic wave field and showed that acoustically fluidized debris behaves as a newtonian fluid with a viscosity in the range 100,000 to 10,000,000 P for plausible conditions.

Heat flow, stress, and rate of slip along the San Andreas Fault, California
TL;DR: In this article, the authors used the absence of a heat flow anomaly greater than ∼0.3 µcal/cm2/sec associated with the San Andreas fault to estimate the upper limit for the steady state or initial shear stress.

Seismic gaps and plate tectonics: Seismic potential for major boundaries
TL;DR: In this article, the authors used the theory of plate tectonics to evaluate the potential for future great earthquakes to occur along major plate boundaries. And they found that the majority of seismic slip occurs during large earthquakes, i.e., those of magnitude 7 or greater.
