To determine factors controlling permeability variations within and adjacent to a fault-hosted geothermal reservoir at Dixie Valley, Nevada, we conducted borehole televiewer observations of wellbore failure (breakouts and cooling cracks) together with hydraulic fracturing stress measurements in six wells drilled into the Stillwater fault zone at depths of 2-3 km. Measurements in highly permeabl...

This archeoseismologic study focuses on the Leukos settlement that thrived west coast of forearc island Karpathos in 4th−6th centuries CE. The onshore site occupies eastern rim offshore Basin, deepest Aegean basin, a sector Hellenic typically regarded as seismically insignificant. Investigations faulting, sedimentary processes, and secondary earthquake effects (hydraulic fracturing, liquefactio...

Right-lateral surface displacement reaching 11⁄2 centimeters occurred over a ten-kilometer section of the Imperial fault in association with a magnitude 3.6 earthquake on March 4, 1966, the smallest known earthquake yet associated with surface displacement. The displacement is documented by field observations of en-echelon cracking in pavement and the offset of the white center line of Highway ...
