We start our tour at the southern end of the Cajon Pass. San Andreas Fault in relation to the tectonic plates The Tour Begins During this trip, when you either drive or straddle over the fault line, we hope you feel how significant of a thing you’re passing over.īelow is that World map of tectonic plates. The next plate boundary to the west is on the other side of the Pacific Ocean. You’ll see that the next plate boundary to the east of the San Andreas is in the middle of the Atlantic Ocean where the North American Plate meets the Eurasian and African Plates. If you watch our YouTube virtual video tour below, you’ll see the map of the World’s tectonic plates. It is important to note however, that the San Andreas Fault is the division of one of those two huge tectonic plates mentioned earlier. Many such lessons even start off with a map of the supercontinent Pangaea, but we’re not going to subject you to that. Tectonic PlatesĮvery geology lesson starts out with looking at a map of the World showing where all the tectonic plates are located. In some places, the zone can be just twenty feet wide and other places it can be almost a mile wide. This zone can be filled with multiple fractures. This grinding action has gone on for millions of years and is what causes earthquakes as well as the features you will see on our tour.ĭuring the tour, keep in mind that the fault is just not a crack in the earth. It is a “plate boundary” where the Pacific and North American Plates meet and grind past each other.
Some of us living in Southern California have heard of other faults like the Helendale, San Jacinto and Elsinore faults but the San Andreas is different. Most people have heard of the dreaded San Andreas Fault yet many of the State’s greatest earthquakes did not happen along the San Andreas. California is covered with earthquake faults.
