Abstract Following observations made in a survey campaign along the Lost River Fault (Idaho, USA) 2019, we integrate both original and previously published data to obtain detailed segmentation of fault sections that failed 1983 Borah Peak earthquake (Mw 6.9). The ruptured topographic surface with an oblique-normal faulting mechanism, activating two SW-dipping segments (Thousand Springs Warm Spr...

We propose a new approach to quantifying fault system geometry, using an objective fit of the fault geometry to a test function, specifically here a fault branch. Fitting a Y-shaped object using a cost function to dextral faults in California, we find a number of significant results arising from use of a a systematic, objective, quantitative approach. (1) The largest angle of the branch structu...

Thrusting implication in the crustal thickening history of eastern Tibet is highly debated. The ?250 km-long Muli thrust Yalong belt SE a major Miocene structure with pronounced topographic step (?2,000 m). Using thermo-kinematic modeling based on thermochronology data, we constrain geometry as being steep (>70°) at surface, agreement field observations, and flattening depth (?20 km) an intra-c...

We present a new strategy to estimate the geometry of a rupture on a finite fault in real time for earthquake early warning. We extend the work of Cua and Heaton who developed the virtual seismologist (VS) method (Cua, 2005), which is a Bayesian approach to seismic early warning using envelope attenuation relationships. This article extends the VS method to large earthquakes where fault finiten...

In this paper, we deal with two important issues in relation to modular reconfigurable manipulators, namely, the determination of the modular assembly configuration optimally suited to perform a specific task and the synthesis of fault tolerant systems. We present a numerical approach yielding an assembly configuration that satisfies four kinematic task requirements: reachability, joint limits,...

[1] We introduce a new model which both generates a self[Stirling et al., 1996]. To get at these issues from a organizing complex segmented fault system which then theoretical point of view, we need to tackle both the issue accommodates finite strain, and generates sequences of of fault system geometry, and event dynamics, over many elastodynamic events on that complex fault system. This earthq...

This paper presents a new approach of joint velocities redistribution for kinematic fault-tolerant control of redundant robot. The suggested approach unlike the locking of failed joints can distribute special velocities to some joints of robot before or after the trouble take place, so that the robot can avoid suffering from worse joint positions and orientations, and its fault-tolerant ability...
