Hydroacoustic tertiary (T-) waves are seismically generated acoustic waves that propagate over great distances in the ocean sound channel with little loss in signal strength. Hydrophone recorded T-waves can provide a l ...

During the Cenozoic, tectonics in the Cuyama basin of the southeastern Salinian block changed from extension to strike-slip faulting to compression and rotation. During the Oligocene-early Miocene, the Cuyama basin was a ...

The Upper Ojai Valley is a tectonic depression between opposing reverse faults, Its northern border is formed by the active, north-dipping San Cayetano fault with 6.0 km of dip-slip displacement in the Silverthread oi ...

Satellite image interpretation, geologic mapping, and paleoseismic trenching are used to investigate the Trans-Yamuna active fault system in the northwestern Doon Valley of the Indian Himalayan foothills. This east-wes ...

Surface and subsurface mapping are combined to determine the geologic history along the San Gabriel fault near the town of Castaic. Palomas Gneiss, Whitaker Granodiorite, and Pelona Schist are basement terranes encoun ...

Detailed subsurface structure contour maps and cross sections have shown the northern Los Angeles basin to be underlain by a south facing monocline that is complicated by secondary faults and folds. The monocline forms ...
