Subtitle San Andreas -

The San Andreas is a , meaning two tectonic plates are sliding past each other horizontally.

The San Andreas Fault is perhaps the most famous geological feature in the world, slicing through California like a jagged scar. For scientists, it is a laboratory for plate tectonics; for residents, it is a constant reminder of the "Big One." 1. A Masterpiece of Plate Tectonics subtitle San Andreas

Stretches from the Coachella Valley to the Salton Sea. This area is of particular concern to seismologists, as it hasn't seen a major rupture in over 300 years, suggesting it is heavily "loaded" with tectonic stress. 3. Impact on Landscape and Infrastructure The San Andreas is a , meaning two

This movement isn't smooth; the plates are "locked" together by friction. Pressure builds up over decades until the rocks break, releasing energy as an earthquake. A Masterpiece of Plate Tectonics Stretches from the

Known for "fault creep," where the plates slide past each other relatively steadily without producing large, destructive quakes.

(on the west) is moving northwest relative to the North American Plate (on the east).

Major infrastructure, including the California Aqueduct and several interstate highways, crosses the fault. Engineers must use specialized "slip joints" and flexible materials to ensure these lifelines don't snap during a rupture. 4. Preparing for the "Big One"
