Geological Survey. The Transverse Ranges (or more accurately, the Los Angeles Ranges) are a group of mountain ranges of southern California, one of the various North America n Coast Ranges that run along the Pacific coast from Alaska to begin at the southern end of the California Coast Ranges and lie between Santa Barbara and San Diego counties.

They derive the name Transverse Ranges due to their. Active deformation in southern California occurs in two discrete structural provinces. To the south of ~34°N latitude, the Peninsular Ranges structural province is characterized by northwest-trending strike-slip faulting, northwest motion of crustal blocks relative to stable North America, and negligible vertical-axis block rotation.

These islands have been uplifted by faulting and folding associated with the collision of the North American and Pacific plates and the rotation of the Transverse Ranges block. Paleomagnetic data indicates that the Transverse Ranges block has rotated ° from its original orientation File Size: KB.

This detailed study of a km-long section of the Sierra Madre and associated fault zones in the central transverse Ranges, along the south side of the San Gabriel Mountains, is aimed at providing information for evaluating the seismic hazard that these faults pose to the heavily populated area immediately to the south.

Recent studies have provided evidence for large earthquakes in the Western Transverse Ranges of California, USA. in reverse faulting regimes can play in assessing seismic hazard. The sites identified above are characterised by generally low gradients, making them ideal for the accumulation of low-energy sediments amenable to radiometric dating, such as the sands and interbedded peats at Pallett Creek (Sieh, a, Sieh, b, Sieh,Sieh et al., ).The Big Bend, by comparison, while sharing similar rainfall patterns leading to intermittent deposition and Cited by: Late Cenozoic tectonics of the east Ventura Basin, Transverse Ranges, California.

Most of central and northern California rests on a crustal block that is being torn from the North American continent by the passing Pacific plate of oceanic crust. Southern California lies at the southern end of this block, where the Southern California faults create a complex and even chaotic landscape of seismic activity.

Description Recent reverse faulting in the Transverse Ranges, California EPUB

As a result of earthquakes big and small, many landforms in the Southern California area grew to be perpendicular, or transverse, to the general orientation of the coastline. In practical terms, this geological change is one of the reasons that Southern California has developed in the way that it has.

The "Big Bend" region of the San Andreas fault (SAF), in the western Transverse Ranges of southern California (), is a zone of relatively large transpression due to the left–stepping, right–slip fault geometry (Davis, ).This transpression has produced widespread thrusting and folding, both north and south of the SAF, that has significantly increased crustal thickness (for.

Transverse Ranges, California Flexural-slip faulting is also documented in the Ventura Basin, California, northeast of Santa Paula, where Pliocene- Pleistocene strata are strongly folded and locally overturned on the north flank of the Santa Clara syncline and are overlain the authoritative version for attribution.

The Transverse Ranges Purpose: To locate and identify the importance and uniqueness of the region known as the Transverse or east-west oriented mountain ranges of California. Location A.

The only major east-west trending mountain region in the state. North of the Peninsular ranges. plex fault systems evolve and dynamically interact.

In this paper, we explore the interactions of inter-secting faults from a location where ample preexisting data help to define fault behavior.

The Transverse Ranges of southern California provide examples of interacting faults at several levels (Fig. 2c).This. Transverse Fault Example Transverse faults occur when a block of rock fractures, and the two blocks of rock slide past each other, in opposite directions.

Compression, tension, and wrenching or twisting all contribute to movement along a transverse fault.The Active Tectonics and Seafloor Mapping Lab is part of the College of Earth, Ocean, and Atmospheric Sciences at Oregon State University.
