Recently earth quakes rocked New Zealand, one result was a dramatic nearly instantenous rise in the sea floor near a particular beach resulting in what almost looks like a man made wall. The formation is actually a piece of the seafloor that rose so suddenly that when photographers arrived within a day or so of its appearance there was green seaweed rooted on the top which once was bouyant and moved erect with the waves and was now hanging down on the wall like formation like wet hair. even more strange some crab and lobster like creatures remained alive among the still wet seaweed. The sudden appearance of these wall like formations are not unheard of in active earth quake zones. Many can be observed on dry land though their wall like appearance is often softened by erosion over the years and vegetation. These features are called ESCAEPMENTS . Click on the word to learn more about them.
What's truly unusual about this most recently appearing escarpment is its origin on the seafloor and the recency of its appearance with its oceanic biota still clinging. We often speak of geologic time as if geologic events always unfolded at a snail's pace. Most people can make the exception for the occasional volcanic eruption, but vulcanism isn't the only instant geological change.
