““Each scenario is about fifteen million years into the future, and each assumes that the Pacific Plate will continue to move northwest at about 2.0 inches per year relative to the interior of North America. In scenario 1, the San Andreas fault is the sole locus of motion. Baja California and coastal California shear away from the rest of the continent to form a long, skinny island. A short ferry ride across the San Andreas Strait connects LA to San Francisco. In scenario 2, all of California west of the Sierra Nevada, together with Baja California, shears away to the northwest. The Gulf of California becomes the Reno Sea, which divides California from Nevada. The scene is reminiscent of how the Arabian Peninsula split from Africa to open the Red Sea some 5 million years ago. In scenario 3, central Nevada splits open through the middle of the Basin and Range province. The widening Gulf of Nevada divides the continent form a large island composed of Washington, Oregon, California, Baja California, and western Nevada. The scene is akin to Madagascar’s origin when it split form eastern Africa to open the Mozambique Channel.””
