18 de mai. de 2021 · Our goal is to study and map surficial processes and landforms related to tectonism, specifically the San Andreas Fault system. With computer processing to remove vegetation, highly accurate, bare-earth digital elevation models of the ground surface are derived to aid in more accurately mapping fault scarps, lineaments, landslides, and geology ...
The San Andreas is the "master" fault of an intricate fault network that cuts through rocks of the California coastal region. The entire San Andreas fault system is more than 800 miles long and extends to depths of at least 10 miles within the Earth. In detail, the fault is a complex zone of crushed and broken rock from a few hundred feet to a ...
The San Andreas Fault is a place where two tectonic plates touch, the North American and Pacific Plates. The plates are rigid (or almost rigid) slabs of rock that comprise the crust and upper mantle of the Earth. The SAF is about 700 miles long as the crow flies and about 800 miles long when its curves are measured.
Histoire et culture. La faille de San Andreas, située en Californie, est une faille géologique, en décrochement, à la jonction des plaques tectoniques pacifique et nord-américaine. Cette grande faille qui passe notamment par San Francisco et Los Angeles provoque des séismes très importants et dévastateurs en Californie .
The San Andreas Fault, at least the current, modern one, has not been the only transform boundary that has existed in this location. In the southern section, there have been at least two previous iterations (Powell and Weldon, 1992). More importantly, a ‘new’ San Andreas appears to be forming in eastern California and western Nevada.

San Francisco has historically suffered significant earthquakes, notably in 1906 and 1989. The average rate of movement along the San Andreas Fault is between 30mm and 50mm per year over the last 10 million years. If current rates of movement are maintained Los Angeles will be adjacent to San Francisco in approximately 20 million years.
