Stress field constraints on intraplate seismicity in eastern North America

ML Zoback - Journal of Geophysical Research: Solid Earth, 1992 - Wiley Online Library
Focal mechanisms of 32 North American midplate earthquakes (mb= 3.8–6.5) were
evaluated to determine if slip is compatible with a broad‐scale regional stress field derived …

Stress and the direction of slip on fault planes

JW Gephart - Tectonics, 1990 - Wiley Online Library
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 …
