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 ...

Abstract The Pacific plate, which is the largest oceanic plate on Earth, has implications for general understanding of dynamics, including origin intraplate stress and driving force motion. However, this currently limited by scarcity geophysical geological observational data. In study, an instantaneous global mantle flow calculation was performed to predict field regimes using a geodynamic mode...

[Abstract Although seismic and stratigraphic well information put tight constraints on rift basin evolution, eroded shoulders commonly expose polydeformed prerift basement whose deformation history may be difficult to constrain. In this work, we apply K‐Ar dating of fault gouge samples from 18 faults explore the brittle well‐exposed eastern margin northern North Sea rift. We find evidence clay ...

The Cainozoic history of the Malanna area included faulting, deposition of sediments by streams or in lakes and swamps, two epochs of planation, and stream erosion. There is no physiographic, depositional or structural evidence for gladation in this area, the type area of Lewis's Malanna Phase of the Pleistocene glaciation. This phase must be considered invalid on the eviaence available in the ...

A novel approach to the automatic detection of fault surface images in 3D seismic datasets is presented. Based on the premise that seismic faulting introduces discontinuities into the rock layering (that is, the horizons), a coherency measure is used to detect points of significant horizon discontinuity. A highest confidence first (HCF) merging strategy is then combined with a flexible surface ...

Appreciable injection-induced seismicity has been occurring in northcentral Oklahoma since 2009. To better understand these earthquakes, we have compiled new information on the state of stress in the state to compare it with both mapped faults and faults inferred from earthquake epicenters and focal plane mechanisms. Seventy-five new in situ stress orientations are available from wellbores thro...
