THere is more to it when we look at the general picture, and in particular the rear portion of hte ice sheet
The whole IS has got loose, we have indeed the creation of a shear zone that baking is indicating, but the whole sheet is moving in a north-north-east direction. The crack at its back has lengthened and hugely widened since first reported a little more than 2 years ago, and is now (purple cross section) about 2.3km wide.
At the same time, it is bound to end up in the open water separating the IS from the tongue, along one of the 2 main cracks underlined in green. the are currently growing fast, each hi-res pictures brings some change
And on the western side, the orange crack are multiplying, leading most likely to another shear zone.
Definitely the event to follow in the coming months, or maybe even weeks.
