You might think that, by now, people would have become accustomed to the idea of natural catastrophes. We live on a planet that is still cooling and which has fissures and faults in its crust; this much is accepted even by those who think that the globe is only six thousand years old, as well as by those who believe that the earth was "designed" to be this way. Even in such a case, it is to be expected that earthquakes will occur and that, if they occur under the seabed, tidal waves will occur also. Yet two sorts of error are still absolutely commonplace. The first of these is the idiotic belief that seismic events are somehow "timed" to express the will of God. Thus, reasoning back from the effect, people will seriously attempt to guess what sin or which profanity led to the verdict of the tectonic plates. The second error, common even among humanists, is to borrow the same fallacy for satirical purposes and to employ it to disprove a benign deity.

There were more than a dozen extinction level events before even the dinosaurs got theirs!

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.

Much as I admired the elegance of physical theories, which at that time geology wholly lacked, I preferred a life in the woods to one in the laboratory.
