[1] Using dynamic rupture models, we examine the response of compliant fault zones that surround pre‐existing faults to nearby earthquakes. We find that some portions of a compliant fault zone can experience inelastic deformation due to dynamic stress perturbations, while the remaining portions deform elastically. Inelastic response of the fault zone results in sympathetic fault‐parallel motion...

This study reports on the cosmogenic 36Cl dating of two normal fault scarps in western Turkey, that Manast?r and Mug?rtepe faults, beyond existing historical records. These faults are elements Manisa Fault Zone (MFZ) seismically active Gediz Graben. Our modeling revealed underwent at least surface ruptures 3.5 ± 0.9 ka 2.0 0.5 ka, with vertical displacements 3.3 m 3.6 m, respectively. An event ...

[1] Pore pressure changes are rigorously included in Coulomb stress calculations for fault interaction studies. These are considered changes under undrained conditions for analyzing very short term postseismic response. The assumption that pore pressure is proportional to faultnormal stress leads to the widely used concept of an effective friction coefficient. We provide an exact expression for...

[1] The initiation of frictional instability is investigated for simple models of fault zone using a linearized perturbation analysis. The fault interface is assumed to obey a linear slipweakening law. The fault is initially prestressed uniformly at the sliding threshold. In the case of antiplane shear between two homogeneous linearly elastic media, space-time and spectral solutions are obtaine...

Determining the relationship between crustal movement and faulting in thrust belts is essential for understanding the growth of geological structures and addressing the proposed models of a potential earthquake hazard. A Mw 5.9 earthquake occurred on 21 January 2016 in Menyuan, NE Qinghai Tibetan plateau. We combined satellite interferometry from Sentinel-1A Terrain Observation with Progressive...

Existing data on source parameters of large crustal earthquakes (subduction events are not considered here) over a wide range of repeat imes indicate that, for a given magnitude (Ms or Mw), earthquakes with long repeat times have shorter fault lengths than those with short repeat imes. A shorter fault length for a given magnitude indicates a larger average stress drop which reflects the average...

[1] We systematically investigate the velocity contrast along the Calaveras fault that ruptured during the 1984 Morgan Hill earthquake using fault zone head waves (FZHW) that refract along the fault interface. We stack waveforms in 353 sets of repeating clusters, and align the peaks or troughs of the direct P waves assuming rightlateral strike-slip focal mechanisms. The obtained velocity contra...
