Massive crack in Antartica's Pine Island Glacier growing

A 3D simulation video from NASA gives viewers an amazingly close view of a gigantic glacier breaking apart off the western edge of Antartica.
-snip-

After the crack’s discovery in October, NASA got an even more expansive photo of the damage using its Terra AM earth-observing satellite. Scientists determined the crack is 260 feet wide and 195 feet deep, almost down to sea level, and it’s only growing.

Scientists aren’t sure of the precise cause of the crack, but believe it is related to the rapidly thinning ice of the Pine Island Glacier, itself thought to be caused by warm water melting the undersides of the glacier’s edges. As more ice melts and breaks apart, scientists are concerned about the effect the process will have on sea levels worldwide, especially in coastal regions, where they could cause “slow motion flooding.”

That's why there is only one crack and not a lot of little foot steps....
