Three-dimensional finite-element modeling was performed to investigate the response to
fractures of the Formation MicroScanner (Mark of Schlumberger), which records high …

The orientation and relative magnitudes of in situ tectonic stress in the continental United
States have been inferred from a variety of indicators, including earthquake focal …

The shear stress direction on a fault plane depends only on four of the six components of the
stress tensor. Assuming only that the slip direction marks the shear stress direction on any …

Stress directions have been determined to depths of 4.5 km in eastern North America from
borehole elongation measured by dipmeter calipers in 47 wells. The average maximum …

Intra-plate stress is governed on a global scale by plate boundary configuration and the
disposition of continents. When continents are assembled into Pangaea-type masses, they …

Using commercial hydrofracture data to supplement published stress data, we map regional
variations in least horizontal stress magnitude (Sh) and orientation within the Paleozoic …

A model based on probability theory is proposed to determine the orientation of the tectonic
stress field from fault slip and earthquake focal mechanism data. On the assumptions that (1) …

An extensive body of geologic data including the modern state of stress, historical seismicity,
surface and subsurface stratigraphy, numerical models of crustal deformation, surficial …

The configuration of six possible paleostress tensors have been derived from 152 faults
measured in eastern Vermont and western New Hampshire. Populations of potentially …

Historic triangulation data have been analysed to determine whether intraplate seismicity is
associated with ongoing ductile deformation in the lower crust. The model we have …
