Geodesy shows that ?7 mm/yr of dextral shear is accumulating across the Central Walker Lane in absence through-going strike-slip faults. To better understand how this accommodated, we describe and quantify patterns slip rates active faults extending between Lake Tahoe basins. Lidar data geomorphic mapping show linear fault traces stepping geometries consistent with accommodation oblique-slip mo...

[1] Field observations of mature crustal faults suggest that slip in individual events occurs primarily within a thin shear zone, <1–5 mm, within a finely granulated, ultracataclastic fault core. Relevant weakening processes in large crustal events are therefore suggested to be thermal, and to involve the following: (1) thermal pressurization of pore fluid within and adjacent to the deforming f...

Previous work has shown that velocity-weakening friction produces slip complexity in simple dynamical models of earthquake faults ( Carlson and Langer, 1989). Rere I show that a different type of dynamical instability, caused by slipweakening friction, also produces slip complexity. The deterministically chaotic slip complexity produced by slip-weakening friction in a simple one dimensional mod...

The article outlines the main findings and conclusions of the QUAKER research project and other related studies on the behaviour of foundations built on top of a rupturing dip-slip fault. Although emphasis is placed on normal faults, the derived conclusions are valid for reverse faults, as well. A key conclusion is that it is quite feasible to design a foundation to withstand an underneath rupt...

0272-1732/99/$10.00  1999 IEEE Hardware verification accounts for a considerable portion of the costs in the microprocessor design process. Traditionally, designers have verified microprocessor designs using simulation techniques that help find most design faults. However, simulation never guarantees the correct operation of the final product. Some design faults are very difficult to detect by...

Recent geodetic studies have shown that slow-slip events can occur on subduction faults, including their shallow (<15 km depth) parts where tsunamis are also generated. Although observations of such now widespread, the physical conditions promoting remain poorly understood. Here we use full waveform inversion controlled-source seismic data from central Hikurangi (New Zealand) margin to constrai...

iran is one of the limited numbers of ancient countries which is almost totally located on earthquake belt. earthquakes have always been the most important natural hazard in iran. many villages, cities, civilizations and monuments have been partly or totally destroyed by past earthquakes in iran. as a developing country, iran is expanding its cities, industries, dams, power plants etc. the rece...

Numerous observational papers on crack populations in the material and geological sciences suggest that cracks evolve in such a way as to organize in specific patterns. However, very little is known about how and why the self-organization comes about. We use a model of tensile-like cracks with friction in order to study the time and space evolution of normal faults. The premise of this spring-b...

[1] Deformed fluvial terraces preserved over active thrust-related folds record the kinematics of folding as fault slip accumulates on the underlying thrust. In the Mackenzie Basin of southern New Zealand, the kinematics revealed by folded fluvial terraces along the active Ostler and Irishman Creek fault zones are inconsistent with traditional models for thrust-related folding in which spatiall...
