Interseismic strain accumulation along the western boundary of the Indian subcontinent [PDF]
, 2012 Despite an overall sinistral slip rate of approximately 3 cm/yr, few major earthquakes have occurred in the past 200 years along the Chaman fault system, the western boundary of the India Plate with the Eurasia Plate.

The effects of rheological layering on post-seismic deformation [PDF]
, 2006 We examine the effects of rheological layering on post-seismic deformation using models of an elastic layer over a viscoelastic layer and a viscoelastic half-space. We extend a general linear viscoelastic theory we have previously proposed to models with

Recovery Characteristics of a Flux-lock Type HTSC Fault Current Limiter after Fault Removal [PDF]
Journal of the Korean Institute of Electrical and Electronic Material Engineers, 2007 To apply the superconducting fault current limiter(SFCL) into a power system, the analysis for its recovery characteristics as well as the consideration for its cooperation with other protecting machine such as a circuit breaker is required. The recovery characteristics of the flux-lock type SFCL like its current limiting characteristics are dependent ...

Mechanics of earthquakes [PDF]
, 1994 An earthquake is a sudden rupture process in the Earth’s crust or mantle caused by tectonic stress. To understand the physics of earthquakes it is important to determine the state of stress before, during, and after an earthquake.
