Fluid‐filled fractures and microcracks are the most stress sensitive component of crustal rock
and often determine the pathways and volume of crustal fluid movement. If we are to …

From the analysis of local earthquake coda waves recorded by the Benioff short‐period
vertical seismograph at Riverside, California, we found a surprisingly large and systematic …

There are currently three major competing views on the essential geometrical, mechanical,
and mathematical nature of faults. The standard view is that faults are (possibly segmented …

The shear-wave splitting observed along almost all shear-wave ray paths in the Earth's crust
is interpreted as the effects of stress-aligned fluid-filled cracks, microcracks, and …

Pore pressure changes are rigorously included in Coulomb stress calculations for fault
interaction studies. These are considered changes under undrained conditions for analyzing …

It is 10 years since shear-wave splitting, thought to be diagnostic of some form of seismic
anisotropy, was first positively identified in the Earth's crust. From the beginning it was …

This study was conducted in order to characterize the frequency, orientation, and aperture of
macroscopic fractures in the crust and their effect on physical properties over an appreciable …

Three-component borehole seismic profiling of the recently active Oroville, California,
normal fault and microearthquake event recording with a near-fault three-component …

Shear wave splitting manifested as leading shear wave polarization, that is, parallel
alignment of leading shear wave particle motions from a variety of sources, has been …

A mobile seismic array of seven stations was deployed at 11 sites along the fault trace of the
M7. 4 Landers earthquake of June 28, 1992, with a maximum offset of 1 km from the trace …
