Modes of extensional faulting controlled by surface processes [PDF]

open access: yes, 2014
We investigate the feedbacks between surface processes and tectonics in an extensional setting by coupling a 2-D geodynamical model with a landscape evolution law.

Possible role of crustal flexure in the initial detachment of extensional allochthons [PDF]

open access: yes
The existence of low-angle normal faults indicates that the ratio of shear stress (TAU) to normal stress (sigma sub N) needed to cause slip on faults is substantially less than would be predicted based on experimental data. Because the tensional strength

Fault detection of helicopter gearboxes using the multi-valued influence matrix method [PDF]

open access: yes
In this paper we investigate the effectiveness of a pattern classifying fault detection system that is designed to cope with the variability of fault signatures inherent in helicopter gearboxes.

Investigation of the Relationship of Earthquakes and Underground Waste Disposal in The El Dorado Area, Arkansas [PDF]

open access: yes, 1991
From December, 1983 to September, 1989 twelve small earthquakes were recorded for the El Dorado, Arkansas area. Magnitudes of these earthquakes were well below damaging levels.

Research on the deformation and failure law and control technology of surrounding rock in the dense roadway area in footwall of normal fault

open access: yesFrontiers in Earth Science
To solve the problem of large deformations and failure of rocks surrounding a dense area at the footwall of a normal fault, we considered the F22 fault in the fourth mining area of Dashucun coal mine in Hebei Province as the research object and conducted

Parallel resonance type fault current limiting circuit breaker

open access: yesHigh Voltage, 2019
The main goal of this study is introducing a novel fault current limiter based on parallel resonance structure (PRFCL) for high voltage application. During normal mode, the PRFCL reactor is short-circuited via a rectifier bridge DC output voltage and LC ...

Co-seismic deformation during the M_w 7.3 Aqaba earthquake (1995) from ERS-SAR interferometry [PDF]

open access: yes, 2000
The M_w 7.3 1995 Aqaba earthquake is the largest instrumental earthquake along the Dead Sea Fault. We complement previous seismological studies by analyzing co‐seismic ground displacement from differential interferometry computed from ERS images spanning

The role of fluid pressure in induced vs. triggered seismicity. Insights from rock deformation experiments on carbonates [PDF]

open access: yes, 2016
Fluid overpressure is one of the primary mechanisms for tectonic fault slip, because fluids lubricate the fault and fluid pressure reduces the effective normal stress that holds the fault in place.
