Do intraplate and plate boundary fault systems evolve in a similar way with repeated slip events?

نویسندگان

چکیده

As repeated slip events occur on a fault, energy is partly dissipated through rock fracturing and frictional processes in the fault zone radiated to surface as seismic energy. Numerous field studies have shown that core of intraplate faults wider average with increasing total displacement (and hence events). In this study we compile data thickness, internal structure (e.g., composition, host juxtaposition, direction, type, and/or number strands) plate boundary compare (within interior tectonic plates). Fault thickness show are anomalously narrow by comparison they remain regardless how much experienced or local fault. By examining scaling relations between moment, rupture length for ruptures, find given value an individual earthquake, earthquakes typically greater moment earthquake magnitude) than events. We infer do not process intact during faults. Thus, dissipate less meaning displacement, more manifested higher magnitude earthquakes. contrast, get increases, generating complex zones damage surrounding propagating linkage neighbouring structures. The geometry, has be consumed at depth reaches surface.

HALL AND LON-SLIP EFFECTS ON MAGNETO-MICROPOLAR FLUID WITH COMBINED FORCED AND FREE CONVECTION IN BOUNDARY LAYER FLOW OVER A HORIZONTAL PLATE WITH VISCOUS DISSIPATION

In this paper, we study the effects of Hall and ion-slip currents on the steady magneto-micropolar of a viscous incompressible and electrically conducting fluid over a horizontal plate by taking in to account the viscous dissipation effects. By means of similarity solutions, deviation of fundamental equations on the assumption of small magnetic Reynolds number are solved numerically by using qu...

Boundary conditions and event scaling of granular stick-slip events

We describe experiments on stick-slip failure of a granular material within a linear shear cell. The experiments are performed in a quasi-two-dimensional photoelastic granular material which is sheared via a slider block and spring moving at a constant velocity. The apparatus can provide either constant-volume or constant dP/dV boundary conditions on the aggregate, and we observe boundary-condi...

   An investigation is carried out on MHD stagnation point flow of water-based nanofluids in which the heat and mass transfer includes the effects of slip and convective boundary conditions. Employing the similarity variables, the governing partial differential equations including continuity, momentum, energy, and concentration have been reduced to ordinary ones and solved by using...
