Increased rate of acceleration on Pine Island Glacier strongly coupled to changes in gravitational driving stress
Increased rate Pine Island Glacier strongly
2014/5/20
Pine Island Glacier, Antarctica, has been un-dergoing several related changes for at least two decades;
these include acceleration, thinning and grounding line re-treat. During the first major ground...
Spatio-temporal Slip, and Stress Level on the Faults within the Western Foothills of Taiwan: Implications for Fault Frictional Properties
The Chi-Chi earthquake fault friction fault rheology stress fault slip distribution
2014/4/15
We use preseismic, coseismic, and postseismic GPS data of the 1999 Chi-Chi earthquake to infer spatio-temporal variation of fault slip and frictional behavior on the Chelungpu fault. The geodetic data...
Is the critical Shields stress for incipient sediment motion dependent on channel-bed slope?
critical Shields stress incipient sediment motion channel-bed slope
2014/4/8
Data from laboratory flumes and natural streams show that the critical Shields stress for initial sediment motion increases with channel slope, which indicates that particles of the same size are more...
Stimulated infrared emission from rocks: assessing a stress indicator
Stimulated infrared emission rocks assessing stress indicator
2010/9/28
To study the effect of stress-activated positive hole (p-hole) charge carriers on the infrared (IR) emission from rocks, we subjected a portion (~10 vol.%) of a large (30×60×7.5 cm3) block of anorthos...
Stress buildup in the Himalaya
seismic cycle interseismic microseismicity geodesy Himalaya Nepal
2014/4/15
The seismic cycle on a major fault involves long periods of elastic strain and stress accumulation, driven by aseismic ductile deformation at depth, ultimately released by sudden fault slip events. Co...
On the use of dislocations to model interseismic strain and stress build-up at intracontinental thrust faults
continental deformation dislocation flexure of the lithosphere seismotectonics
2014/4/15
Creeping dislocations in an elastic half-space are commonly used to model interseismic deformation at subduction zones, and might also apply to major intracontinental thrust faults such as the Main Hi...
