The macroscopic behaviour of a fault zone can be described by a classic Coulomb friction law and static^kinetic rheology. The critical failure stress leading to the activation of a single shear zone segment then depends on the normal stress acting on the future fault plane. It is known that the seismic cycle on a main fault patch can be modulated by surrounding fault activations, leading to int...

We developed a sliding-window cross-correlation (SCC) detection technique and applied the technique to continuous waveforms recorded by the Cooperative New Madrid Seismic Network stations following the 18 April 2008 Illinois earthquake. The technique detected more than 120 aftershocks down to ML 1.0 in the 2 week time window following the mainshock, which is three times more than the number of ...

This letter presents a study of the atomic mechanism of the initiation of motion of a static twin plane under applied mechanical load in a model shape-memory material. By tracking the deformation under load and using linear stability analysis, we find that the eigenvalues of the Hessian matrix provide an indicator of the initiation of motion of the twin plane. The initiation of motion is signal...

The Pasadena earthquake (ML ~4.9) occurred on 3 December 1988, at a depth of 16 km. The hypocenters of the earthquake and its aftershocks define a eastnortheast striking, steeply northwest-dipping surface that projects up to the active surficial trace of the Raymond fault. One of the nodal planes of the focal mechanism of the earthquake parallels the Raymond fault with left-lateral strikeslip m...

The purpose of this article is to compare time based maintenance (TBM) with condition based maintenance (CBM) relative to cutting tools in the process for removing material. We describe the fault detection (FD), method based on the use of the analytical model of the roughness of the work pieces to be machined. This model is established under given cutting conditions and calculated according to ...

We consider a three-dimensional elastic body with a plane fault under a slip-weakening friction. The fault has -periodically distributed holes, called (smallscale) barriers. This problem arises in the modeling of the earthquake nucleation on a large-scale fault. In each -square of the -lattice on the fault plane, the friction contact is considered outside an open set T (small-scale barrier) of ...
