Since we are dealing in the historical sciences, we are also dealing with multiple competing hypothesis. As such, we now know that massive trenches can open up in a geologic blink of an eye; which, as the article points out, weakens the uniformitarian gradualism of Charles Lyll, and stengthens the catastrophic plate tectonics model (based, as it is, on a young, universal flood model).
I'd classify Evolution as a scientific account of a system of natural phenomena; aka "history."
Creationism, however, is neither science or history; it is a doctrine without allowance for skeptical or scientific questioning.
Darwin wrote to Lyell in excitement of witnessing a massive earthquake in Chile and seeing the ground rise over 10 feet instantly – as evidence of uniformitarianism. This is what uniformitarianism predicts – known forces, like earthquakes, moving the earth little by little, 10-20 feet at times. This rift is about 20 feet at its widest. If it were, say, 20 miles wide, or 200 miles, than maybe ‘catastrophists’ would have a point.
