Discover Badwater Basin in Inyo County, California: The lowest point in North America is home to an undrinkable pool surrounded by fields of geometric salt flats. Determining a more accurate location, extent, and hydrologic characteristics of the Rialto-Colton Fault by using geophysical and hydrologic techniques may be the best approach to resolving some of the problems facing water managers in the Rialto-Colton basin and refining the hydrologic concepts of the basin in the vicinity of the fault.

The Ventura Basin is one of the more active tectonic regions of the world. In the basin, the Oak Ridge fault accommodates high rates of oblique crustal strain and, along with several other major faults, is considered a significant seismic hazard to a large urban population.

The M Northridge earthquake occurred on a blind, south-dipping fault beneath the San Fernando. The transfer of present-day activity may be by way of the Holser fault, although that fault is not known to connect with the San Gabriel fault at or near the surface.

Citation Yeats, R. Ridge Basin and San Gabriel fault in the Castaic Lowland, southern California.: Geological Society of America. doi: / The purpose of our study is to identify the main structures in the basin and its borders and to quantify their rate of deformation.

Our study includes the onshore and offshore Ventura basin, the arcuate basin-bounding Oak Ridge reverse fault, and the Oxnard shelf to the south.

Shortening, fault-slip, and crustal-block motions were studied using. The Oak Ridge fault is a large-offset, south-dipping reverse fault that forms the south boundary of the Ventura Basin in southern California.

Previous research indicates that the Oak Ridge fault south of the town of Ventura has been inactive since ka ago and that the fault tip is buried by??. 1 km of Quaternary sediment.

However, very high-resolution and medium-resolution seismic. Shortening is also occurring on the Montalvo Fault and Anticline system along the southeast edge of the map area (part of the broader Oak Ridge Fault Zone; Yeats, ) and on the Rincon-Ventura Avenue Anticline (for example, Rockwell and others, ), which crosses the northwest edge of the map : A.C.

Los Osos fault zone, San Luis Obispo County, California. VENTURA BASIN PROVINCE () By Margaret A. Keller INTRODUCTION The Ventura Basin Province of Southern California consists of the portion of the Western Transverse Ranges that is bounded approximately on the north by the Santa Ynez and Big Pine Faults, on the South of the Oak Ridge Fault along the Oak Ridge Trend, the major producing trend File Size: KB.

Oak Ridge in Santa Clara County, California, is a ridge forming the east canyon wall of Arroyo Hondo, which drains into Calaveras Reservoir. Black Mountain is its highest point.

The first known white settlers on Oak Ridge were the Parks family, who ran cattle on the ridge. Now owned by the San Francisco Water Department, the ridge is private property and is off-limits to most people.

The east Ventura basin originated in the middle Miocene as a rift system bounded on one side by the Oak Ridge-Semi Hills structural shelf and on the other side by a granitic ridge parallel to the.

Wright. Online. The Dry Canyon area is located in the eastern section of the Ventura Basin in northwestern Los Angeles County California. The following problems confronted the writer in this area: (1) the relationships between the marine and the non-marine sediments of the basin (2) the general stratigraphy (3) the faulting along the base of the Sierra Pelona mountain, range which borders the basin on the north.

perhaps due to the uplift of the Oak View area to the south of the Arroyo Parida-Santa Ana fault, also caused the incision of San Antonio Creek and the Ventura River. This work implies that the basin fill in Ojai and Upper Ojai valleys are a separate entity from the rest of the Ventura Basin stratigraphy.
