Abstract Recent field studies provide evidence of fault slip-rate variability over time periods 10–100 k.y., yet researchers do not know how processes internal to the system (e.g., reorganization) impact records slip rates. In this study, we directly observed fault-system evolution and measured histories within a scaled physical experiment dextral strike-slip 15° restraining bend representative...

The North Qinling Fault, located at the boundary of China Block and South Block, represents an important tectonic structure between Weihe Basin Mountains, controls subsidence expansion Basin. This fault has been highly active caused strong earthquakes since Holocene in a pre-seismic stage currently, as indicated by many paleoearthquake traces found along it. To determine present-day activity se...

Distributed storage of data files in different nodes of a network enhances its fault tolerance capability by offering protection against node and link failures. Reliability is often achieved through redundancy in one of the following two ways: (i) storage of multiple copies of the entire file at different locations (nodes) or (ii) storage of file segments (not entire files) at different node lo...

[1] One of the biggest assumptions, and a source of some of the biggest uncertainties in earthquake hazard estimation is the role of fault segmentation in controlling large earthquake ruptures. Here we apply a new model which produces sequences of elastodynamic earthquake events on complex segmented fault systems, and use these simulations to quantify the variation of large events. We find a nu...

We propose a new method for defining segmentation of plate boundaries and faults, based on the directions of the stress tensor. Estimates for these directions are obtained by minimizing the average misfit between the theoretical and observed slip directions on fault planes of earthquake focal mechanisms. The misfit, f, for an individual earthquake is the parameter we use for defining the segmen...

In this article a problem of industrial quality control is investigated. Electric motors have to be tested for proper working by analyzing their emitted noise signal in regular running. The noise signal being (approximately) periodic, it can be seen as a sequence of single signal segments p i (t); i = 1 These segments are represented in the time-frequency space by their time-frequency represent...

In constructing moment-balanced fault rupture models for the SF Bay region, WG99 needed to account for all the moment released by earthquakes in the region. These include earthquakes on characterized rupture sources, earthquakes on other rupture sources (background), and their aftershocks. Some of the aftershocks will be large, with magnitudes sometimes exceeding 6.7. WG99 assumed that an after...

Frictional heterogeneity within fault zones is one of the factors proposed to explain spectrum slow, intermediate, and fast slip behaviors exhibited by faults in nature. Numerical modeling shows how even a simplified model setup incorporating sliding on velocity-weakening (VW) patch surrounded velocity-strengthening (VS) material can reproduce rich variety resembling However, experimental inves...

Dasht-e-Arjan is a northeast trending graben located 65 km west of Shiraz. It was formed along active segments of the Korrehbas fault, perpendicularly to the Shahnesh in and Salamati anticlines. Oriented sampling from bordering fault planes and striations was carried out to evaluate the relative amounts of paleostress/strain needed to form the graben. Measurements of e-twins and c-axis of calci...

Three-dimensional mechanical models are used to evaluate the performance of different fault growth criteria in predicting successive growth of three échelon thrust faults similar to the segments of the Puente Hills thrust system of the Los Angeles basin, California. Four sequential Boundary Element Method models explore the growth of successive échelon faults within the system by simulating sna...
